Engineered Nearest-Neighbour Interactions with Doubly Modulated Optical Lattices
Hongzheng Zhao, Johannes Knolle, Florian Mintert
Optical lattice systems provide exceptional platforms for quantum simulation of many-body systems. We focus on the doubly modulated Bose-Hubbard model driven by both time-dependent…
Floquet Time Spirals and Stable Discrete Time Quasi-Crystals in Quasi-Periodically Driven Quantum Many-Body Systems
Hongzheng Zhao, Florian Mintert, Johannes Knolle
We analyse quasi-periodically driven quantum systems that can be mapped exactly to periodically driven ones and find Floquet Time Spirals in analogy with spatially incommensurate s…
Orbital Magnetic Field Effects in Mott Insulators with Strong Spin-Orbit Coupling
Willian M. H. Natori, Roderich Moessner, Johannes Knolle
We study the effect of a magnetic field on the low energy description of Mott insulators with strong spin-orbit (SO) coupling. In contrast to the standard case of the Hubbard model…
