Nonequilibrium dynamics of doped Chern ferromagnets: a case study for false vacuum decay
Kilian Kuhlbrodt, Olivier Huber, Oliver Breach +7
Even though metastable false vacuum decay is ubiquitous in physics, its underlying dynamics are still not well understood. Dissipative state preparation in moiré quantum materials…
Observation of metastable chiral domain walls in a topological magnet
Richen Xiong, Chenxin Qin, Zhaoyu Han +17
The interplay between topology and correlation can give rise to exotic collective excitations. The integer and fractional quantum anomalous Hall (QAH) magnets recently discovered i…
Electrically Programmable Correlated Topology and Magnetism in a Moiré Trilayer
Christiano Wang Beach, Courtney Baier, Kaijie Yang +15
Strong electron-electron interactions underlie a wide range of quantum many-body phenomena, including magnetism, superconductivity, and charge fractionalization. A central goal is…
Revealing quantum geometry effects in magic angle twisted bilayer graphene using the circular photogalvanic effect
Eylon Persky, Leonie Parisot, Minhao He +7
We report a photocurrent studies of a magic angle twisted bilayer graphene device using near infrared light. Through photocurrent imaging and polarization dependence, we separate t…
Ballistic Exciton Flow Driven by Intertwined Exciton-Electron Orders in a Moiré Superlattice
Shibin Deng, Jonas M. Peterson, Jonas Reimann +7
Moiré superlattices of transition-metal dichalcogenides (TMDs) host strongly interacting Bose-Fermi mixtures in which bosonic excitons coexist with correlated electron lattices. U…
Record magnetoresistance, enhanced superconductivity, and fermiology in WTe2
Gianluca Delgado, Elliott Runburg, Chaowei Hu +12
The diverse electronic properties of transition metal chalcogenides can be very sensitive to crystal imperfections. A new crystal growth technique, known as horizontal flux transpo…
