Collective quantum state at the atomic limit
Fan Zhang, Yanxing Li, Chengye Dong +8
Collective quantum states are often associated with extended systems, where spatially extensive degrees of freedom enable emergent many-body behavior; whether such strongly correla…
Ultrafast photo-thermoelectric currents in graphene junctions in the mid-infrared
Nina Pettinger, Michel Panhans, Johannes Schmuck +8
Graphene is widely recognized for its ultrafast and broadband photocurrent response, but whether the broadband ultrafast characteristics are preserved at mid-infrared wavelengths w…
Superconducting Decoherence and Thermal Quenching of the Josephson Diode Effect in Low-Dimensional Josephson Systems
