13.02.2024 Upcoming SPICE Workshop on Spin textures: Magnetism meets Plasmonics

The mathematical concept of “topology”, developed in the past century, has become the real game changer in condensed matter physics. The particular coupling of the electronic wavefunctions with the spin configuration define the material topology, from which unique electronic properties arise. Skyrmions, anomalous spin Hall effect or topological superconductivity are some examples of the fascinating phenomena and applications that this new concept enables.
Besides the potential technological transfer, topology also paves the way for quantum states, a phenomenal playground for investigating fundamental interactions of correlated electrons under topological protection. On top of these correlated materials, topological superconductivity, essential to the realization of quantum computing, is one of the most “hot research lines”, expected to generate the biggest revolution in the field.
By gathering young researchers from both topology and correlation topics, we aim to get a broad perspective of one of the hottest topics in condensed matter physics. The workshop will count on researchers from both experimental and theoretical fields, aiming to promote collaborations across different perspectives.

13.02.2024 Upcoming SPICE Workshop on Spin textures: Magnetism meets Plasmonics

Spin textures in solids originate from the complex interaction between electrons and atoms. In particular, the collective behavior of electrons is often key to emergent physical properties. For example, the spins of localized as well as itinerant electrons can interact to realize statically (meta-) stable magnetic spin textures, including spin-spirals, vortices, skyrmions, multi-q structures, i.e., magnetic arrangements characterized by multiple wave vectors in their magnetic order parameter.
Alternatively, electrons can be excited collectively by electromagnetic waves such that the electrons oscillate to realize plasmons. Being highly endowed with tunability, the field of plasmonics, has rapidly emulated several interesting spin structures.
In both fields, skyrmions and topological excitations play a crucial role spurred by the idea of robust states of matter for applications including storage and information technology. While there are a lot of similarities between magnetic and electromagnetic spin textures there are also key differences in their physics. For example, each field has its individual challenges to realize tailored spin textures: While a limitation in magnetism is that certain competing interactions are required to realize spin structures, in plasmonics certain field components are prohibited hindering the formation of arbitrary spin structures. External stimuli are interesting for both research fields to manipulate the unique magnetic and electronic properties of the excitations.
This workshop aims to bring together experts from both magnetism and plasmonics to foster the discovery of new spin textures.

13.02.2024 Upcoming SPICE Workshop-School on Quantum Spinoptics

This joint workshop and school aims to bring together students and researchers in the separate fields of solid-state physics and quantum optics, with the goal of fostering an exchange of ideas and knowledge that might spawn a new exciting field of “Quantum Spinoptics.” The common ground for this inter-disciplinary field is the increasingly recognized importance to develop techniques to controllably couple qubits (either atoms or solid-state spins) to interesting quantum “baths” (photons or magnetic materials). Such control is expected to open up diverse scientific and technological opportunities, such as:
- Long-distance coupling and entanglement of qubits through coherent interactions or correlated dissipation
- State protection through correlated dissipation (e.g., subradiance) and associated applications
- Quantum sensing and metrology, and novel probes of condensed matter systems
- Realization of novel classes of out-of-equilibrium dynamics and phases
While these ideas are already starting to be explored separately within solid-state physics and quantum optics, we envision that scientific progress and opportunities will significantly accelerate with the cross-fertilization of ideas. The joint workshop-school format is intended to provide a venue equally devoted to the dissemination of latest research developments, discussion of scientific ideas, and providing a pedagogical background to establish a common “scientific language” for this new field. To that end, the event will feature two extended introductory lectures, featuring scientific and pedagogical leaders within the fields of solid-state physics and quantum optics. We thus especially encourage young scholars to attend and to also contribute in a dedicated poster session.

13.02.2024 Upcoming SPICE Workshop on Nanomagnetism in 3D

The scientific and technological exploration of three-dimensional magnetic nanostructures is an emerging research field with exciting novel physical phenomena, originating from the increased complexity in spin textures, topology, and frustration in three dimensions. Tailored three-dimensional nanomagnetic structures, including in artificial spin ice systems or magnonics will enable novel applications in magnetic sensor and information processing technologies with improved energy efficiency, processing speed, functionalities, and miniaturization of future spintronic devices. Another approach to explore and harness the full three-dimensional space is to use curvature as a design parameter, where the local curvature impacts physical properties across multiple length scales, ranging from the macroscopic to the nanoscale at interfaces and inhomogeneities in materials with structural, chemical, electronic, and magnetic short-range order. In quantum materials, where correlations, entanglement, and topology dominate, the local curvature opens the path to novel phenomena that have recently emerged and could have a dramatic impact on future fundamental and applied studies of materials. Particularly, magnetic systems hosting non-collinear and topological states and 3D magnetic nanostructures strongly benefit from treating curvature as a new design parameter to explore prospective applications in the magnetic field and stress sensing, micro-robotics, and information processing and storage.
Exploring 3d nanomagnetism requires advances in modelling/theory, synthesis/fabrication, and state-of-the-art nanoscale characterization techniques to understand, realize and control the properties, behavior, and functionalities of these novel magnetic nanostructures.
This workshop will bring together experts from different areas in the magnetism community to discuss the challenges and opportunities of expanding nanomagnetism towards the third dimension.

23.07.2023 Upcoming SPICE Workshop on Hybrid Correlated States and Dynamics in Quantum Materials

The SPICE workshop "Hybrid Correlated States and Dynamics in Quantum Materials" will be held from May 14th to 16th, 2024 at the historic WASEM winery, Ingelheim.

The workshop focusses on correlated states of electrons, that give rise to quantum matter, such as ordered magnets, spin liquids, superconductors, and topological materials. The exciting phenomena hosted and technological applications promised by these states of matter have further inspired the scientific community to engineer hybrids where different ingredients for correlations are provided by separate materials coupled together. Thus, such low-dimensional hybrid nanostructures have enabled engineering novel states of matter with intriguing physics, often not admitted by any single platform.

With the recent developments, theoretical and experimental, time reversal symmetry breaking via magnetism has emerged as a powerful tool to engineer novel unconventional superconducting states and phenomena such as nonreciprocity. At the same time, engineering of the superconducting condensate to bear a net spin employing magnet/superconductor hybrids has been demonstrated. This has opened prospects for superconducting spintronics devices enabling dissipationless spin torques and logic. Further, spin fluctuations appear to play a fundamental role in a large fraction of unconventional and two-dimensional superconductors including the recently discovered states in moiré materials. Therefore, these three seemingly disjoint fields are intricately relying on knowledge from each other and can best be tackled with an overview of all three. Providing this overview and a common discussion platform is the main goal of this workshop.

The workshop shall bring together experts and young researchers from three different communities: (i) Magnetism and Spintronics, (ii) Superconductivity and Strongly Correlated Electrons, and (iii) Low-dimensional nanostructures. The purview includes coherent and incoherent magnetization dynamics in conjunction with the various spintronics effects that allow its manipulation and detection. A key topic will be the recently discovered nonreciprocal effects in magnets e.g., chiral magnons, as well as superconductors, e.g., the superconducting diode effect. Recent discoveries regarding two-dimensional materials, multi-orbital superconductivity, Ising superconductors, topological superconductivity and quantum sensors coupled to magnets will also be central to the workshop portfolio. Employing fluctuations of currents (e.g, flow of spin or vortices) to probe the quantum nature of transport will form an exciting topic of discussion across communities. Finally, the case of spin fluctuations mediated superconductivity, that is believed to underlie a wide range of unconventional superconductors can best be discussed with the three communities present at the workshop.

01.07.2023 Upcoming SPICE Workshop on Terahertz Spintronics: toward Terahertz Spin-based Devices

The SPICE workshop "Terahertz Spintronics: toward Terahertz Spin-based Devices" will be held from October 10th to 12th, 2023 at the historic WASEM winery, Ingelheim.

The workshop focusses on THz spintronics, which is a novel research field that combines magnetism and spintronic with ultrafast optics. Although ultrafast demagnetization of ferromagnetic materials at picosecond timescale has been first observed already three decades ago, recent years have seen the rapid development of THz spintronic devices stemming from ground breaking studies. In the last years, the numerous improvements made in material research (such as on topological insulators and antiferromagnetic materials), interface quality and device engineering have been central to both explore spin-based physics at THz frequencies and investigate to new concepts of spin based THz devices. These cover the full THz block chain (broad and narrowband THz generation and detection, together with control of radiation properties such as polarization and ellipticity) as well as new approaches for THz imaging and encoding THz information. This workshop will bring together world-leading scientists from a broad range of communities, generating further collaborations and developmentsin this emerging field.

You can apply online for the workshop until August 14th, 2023.

The SPICE workshop "Altermagnetism: Emerging Opportunities in a New Magnetic Phase" will be held from June 13th to 15th, 2023 at the historic WASEM winery, Ingelheim.

The workshop focuses on the emerging magnetic material class of altermagnets, that show compensated magnetic ordering and alternating spin-polarization in both the direct and momentum space, with a d-wave (or higher even-parity wave) symmetry. The novel properties of altermagnets have links to many fields of research, such as spintronics, ultra-fast photo-magnetism, neuromorphics, multiferroics, magnonics, topological matter, or superconductivity. The workshop brings together junior and senior scientists from diverse research fields to explore this fascinating newly discovered magnetic phase.

You can apply online for the workshop until April 1st, 2023.

09.01.2023 Upcoming SPICE workshop on Non-equilibrium Quantum Materials Design in June

The SPICE workshop "Non-equilibrium Quantum Materials Design" will be held from June 27th to 29th, 2023 at the historic WASEM winery, Ingelheim.

The goal of the workshop is to bring together experts in quantum materials synthesis with experimentalists and theorists investigating non-equilibrium phenomena to spark a new generation of “non-equilibrium quantum materials design.” This nascent research opportunity builds off of recent discoveries of unique phases and functionalities of quantum matter when driven out-of-equilibrium by optical or electrical stimuli. We hope the workshop will allow us to define short- and long-term goals in the field, and ultimately, establish a community working towards the creation of quantum materials with tailored non-equilibrium responses.

You can apply online for the workshop until April 1st, 2023.
