Phase space crystal vibrations: Chiral edge states with preserved time-reversal symmetry
Lingzhen Guo, Vittorio Peano, Florian Marquardt
Abstract
Phase-space crystal is a solidlike crystalline state in phase space formed by atoms, subject to a time-periodic drive. The authors show that interactions between these atoms can give rise to vibrational band structures with nontrivial Chern numbers and chiral edge states in phase space. Remarkably, these arise even in the presence of time-reversal symmetry in contrast to all topological transport scenarios in real space. Phase-space crystal vibrations offer a new platform for phononic topological transport whereby chiral properties arise naturally.
