810. WE-Heraeus-Seminar — Condensates of Light
12. Mai 2024 - 16. Mai 2024 • Physikzentrum Bad Honnef, Deutschland
Veranstalter:
Wilhelm and Else Heraeus-Foundation
Zusammenfassung:
Bose-Einstein condensation has in the last thirty years been observed in several physical systems, including cold atomic gases and exciton-polaritons, which are mixed states of matter and light in solid state systems. Other than massive particles photons usually do not exhibit Bose-Einstein condensation despite having bosonic nature, the background being that in blackbody radiation, as the textbook example for a photonic gas, the chemical potential vanishes, and at low temperature photons vanish instead of exhibiting condensation. More recently, Bose-Einstein condensations of photons has been observed in low-dimensional systems, e.g. by confining light in dye-solution filled optical microresonators, the use of plasmonic nanoparticle arrays or erbium-doped fiber cavities. Quantum fluids of light have allowed for the observation of novel quantum liquid effects, both in the regimes of near and partial thermal equilibrium. The seminar will illuminate the different platforms and the effects observed in this rapidly evolving field.

Hybrid Correlated States and Dynamics in Quantum Materials
14. Mai 2024 - 16. Mai 2024 • Mainz – hybrid, Deutschland
Veranstalter:
This workshop is organized by SPICE as part of the Gutenberg International Conference Center (GICC) at Johannes Gutenberg University Mainz (JGU).
Zusammenfassung:
Correlated states of electrons give rise to quantum matter, such as ordered magnets, spin liquids, superconductors, and topological materials. In lower dimensions, correlations assume a still pronounced importance. 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.

Cavity control of quantum materials
14. Mai 2024 - 17. Mai 2024 • Hamburg (CFEL located at the DESY campus), Deutschland
Zusammenfassung:
Cavities have emerged as a powerful tool for material control, enabling new phases of matter, engineering dynamical processes in cold atoms and altering chemical reaction rates. At the heart of this potentially revolutionary technology lies the fundamental question: to what extent can quantum fluctuations of light be leveraged to control static and dynamical properties of many-body systems through cavities. To tackle this question, we seek to convene experts across diverse research domains focused on cavity-based material control. This interdisciplinary gathering aims to cross fertilize different disciplines with new methods and approaches. In particular topics of interest include: Identifying new avenues of material control using quantum light and addressing the potential and limitations of these physical processes. Exploring new “cavity” platforms such as surface plasmons, photonic crystals or other photonic structures capable of confining light and amplifying quantum fluctuations. Reaching new regimes of light matter coupling and entanglement. Elucidating novel physical phenomena unlocked in light-matter hybrid experiments and unveiling applications of cavities for quantum technologies.

WE-Heraeus-Seminar — Advances in Quantum Simulation and Sensing with Ultracold Gases
24. Jun 2024 - 28. Jun 2024 • Bad Honnef, Deutschland
Zusammenfassung:
Since the first experimental realization of Bose-Einstein condensation in ultracold atomic gases in 1995, there have been several substantial breakthroughs. Today, systems of bosonic or fermionic quantum gases allow for an unprecedented high level of experimental control concerning all ingredients of the underlying many-body Hamiltonian. Therefore, ultracold gases are considered to be ideal quantum simulators, that is, they are best capable to simulate difficult problems in quantum many-body physics as they occur in condensed matter and other fields of physics. In response to the occurrence of many new research directions in recent years, it is highly desirable to give a coherent overview over the diverse facets which are now appearing, and to reflect upon the future perspectives of the field.

Bad Honnef Physics School — Next Generation Quantum Materials: Correlations and Magnetism Meet Topology
15. Sep 2024 - 20. Sep 2024 • Physikzentrum Bad Honnef, Deutschland
Zusammenfassung:
Quantum Materials research is an umbrella term that describes the investigation of strongly correlated electron systems, unconventional magnets and superconductors, and topological phases of matter. In recent years, a new generation of materials has emerged at the intersection of these subfields, which offers a unique opportunity to study the interplay of electronic correlations and topology.
