Controlling the magnetic state of the proximate quantum spin liquid -RuCl with an optical cavity
Emil Vinas Boström, Adithya Sriram, Martin Claassen +1
Harnessing the enhanced light-matter coupling and quantum vacuum fluctuations resulting from mode volume compression in optical cavities is a promising route towards functionalizin…
Witnessing nonequilibrium entanglement dynamics in a strongly correlated fermionic chain
Denitsa R. Baykusheva, Mona H. Kalthoff, Damian Hofmann +4
Many-body entanglement in condensed matter systems can be diagnosed from equilibrium response functions through the use of entanglement witnesses and operator-specific quantum boun…
Ultrafast Spin Dynamics and Photoinduced Insulator-to-Metal Transition in -
Jin Zhang, Nicolas Tancogne-Dejean, Lede Xian +4
Laser-induced ultrafast demagnetization is a phenomenon of utmost interest and attracts significant attention because it enables potential applications in ultrafast optoelectronics…
Moiré Engineering of Nonsymmorphic Symmetries and Hourglass Superconductors
Yifan Gao, Ammon Fischer, Lennart Klebl +5
Moiré heterostructures hold the promise to provide platforms to tailor strongly correlated and topological states of matter. Here, we theoretically propose the emergence of an effe…
Topological Multipartite Entanglement in a Fermi Liquid
Pok Man Tam, Martin Claassen, Charles L. Kane
We show that the topology of the Fermi sea of a -dimensional Fermi gas is reflected in the multipartite entanglement characterizing regions that meet at a point. For odd $…
Dissipation Induced Flat Bands
Spenser Talkington, Martin Claassen
Flat bands are an ideal environment to realize unconventional electronic phases. Here, we show that fermionic systems with dissipation governed by a Bloch Lindbladian can realize d…
