Time Crystals in Coupled Exciton-Polariton Condensates
Xuan Ye, Hong-Jin Xiong, Alexey Kavokin +1
In this paper, we show that time crystals can emerge in coupled exciton-polariton condensates without periodic external driving, enabled instead by incoherent gain and dissipation…

A Generalized Method for Spatial Operations on Physical Properties of Matter
Hongjin Xiong, Teng Ma
The physical properties of matter are typically described by coefficient matrices governed by crystal symmetry. Applying spatial operations, such as rotation, inversion, and mirror…
