Unification of valley and anomalous Hall effects in a strained lattice
Jiale Yuan, Han Cai, Congjun Wu +3
Two dimensional lattices are an important stage for studying many aspects of quantum physics, in particular the topological phases. The valley Hall and anomalous Hall effects are t…
Flat-band localization in Creutz superradiance lattices
Yanyan He, Ruosong Mao, Han Cai +5
Flat bands play an important role in diffraction-free photonics and attract fundamental interest in many-body physics. Here we report the engineering of flat-band localization of c…
Nanoscale High Transition Temperature Superconducting Quantum Interference Device Transimpedance Amplifier
Hao Li, Ethan Y. Cho, Han Cai +1
As the quantum generation of electronics takes the stage, a cast of important support electronics is needed to connect these novel devices to our classical worlds. In the case of s…
Topological phases of quantized light
Han Cai, Da-Wei Wang
Topological photonics is an emerging research area that focuses on the topological states of classical light. Here we reveal the topological phases that are intrinsic to the partic…
Many-body chiral edge currents and sliding phases of atomic spinwaves in momentum-space lattice
Yongqiang Li, Han Cai, Da-wei Wang +3
Collective excitations (spinwaves) of long-lived atomic hyperfine states can be synthesized into a Bose-Hubbard model in momentum space. We explore many-body ground states and dyna…
Observation of momentum-space chiral edge currents in room-temperature atoms
Han Cai, Jinhong Liu, Jinze Wu +4
Chiral edge currents play an important role in characterizing topological matter. In atoms, they have been observed at such a low temperature that the atomic motion can be measured…
