Memory-driven Topological Defects and Unconventional Long-Range Order
Ziyang Ding, Zi Cai
We investigate many-body systems with time-delayed self-interactions mediated by a memory-feedback mechanism. We show that such temporal interactions generate non-equilibrium order…

Emergence of spatial patterns and synchronization in superconducting time crystals
Bo Fan, Zi Cai, Antonio M. García-García
We identify a time crystal phase characterized by a frequency half of the driving frequency in disordered superconductors by employing the time dependent Bogoliubov-de Gennes forma…

Observation of Time Crystal in a Spin Maser System
Weiyu Wang, Mingjun Feng, Qianjin Ma +3
Pair interaction potentials between atoms in a crystal are in general non-monotonic in distance, with a local minimum whose position gives the lattice constant of the crystal. A te…
