Novel quantum magnetic, orbital and topological states with ultra-cold atoms
Abstract
Motivated by the rapid progress of quantum dynamics, we recently constructed the space-time symmetry framework for quantum dynamic systems, which is published at Phys. Rev. Lett. 120, 096401 (2018). Our results serve as a symmetry foundation for studying dynamic systems, including transport and topological properties. It is well-known that crystal symmetries and the Bloch theorem play a fundamental role in condensed matter physics. We extend the concept of static crystal to the dynamic space-time crystal characterized by the general intertwined space-time periodicities in D+1 dimensions, which include both the static crystal and the Floquet crystal as special cases. All of the basic concepts, including the Bloch theorem, bands, need to be generalized for intertwined space-time symmetries.
