Spontaneous breaking of time-reversal symmetry and time-crystal states in chiral atomic systems

MG Silveirinha, H Terças, M Antezza - Physical Review B, 2023 - APS
We present a theoretical study of the interaction between an atom characterized by a
degenerate ground state and a reciprocal environment, such as a semiconductor …

Exploiting spacetime symmetry in dissipative nonlinear multimode amplifiers for output control

CW Chen, K Wisal, M Fink, AD Stone, H Cao - arXiv preprint arXiv …, 2024 - arxiv.org
Time-reversal symmetry enables shaping input waves to control output waves in many linear
and nonlinear systems; however energy dissipation violates such symmetry. We consider a …
