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…

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…
