An instanton-like excitation of a discrete time crystal
Xiaoqin Yang, Zi Cai
Spontaneous symmetry breaking and elementary excitation are two of the pillars of condensed matter physics that are closely related to each other. The symmetry and its spontaneous…

Symplectic ferromagnetism and phase transitions in multi-component fermionic systems
Zi Cai, Congjun Wu
In this paper, we study the itinerant ferromagnetic phase in multi-component fermionic systems with symplectic (Sp(4), or isomorphically SO(5)) symmetry. Two different microscopic…

Pattern formation and exotic order in driven-dissipative Bose-Hubbard systems
Zijian Wang, Carlos Navarrete-Benlloch, Zi Cai
Modern experimental platforms such as supercoducting-circuit arrays call for the exploration of bosonic tight-binding models in unconventional situations with no counterpart in rea…
