Artificial Gauge Fields, Interactions and Non-Equilibrium Quantum Dynamics

Karyn LE HUR (CPHT, Ecole Polytechnique, Palaiseau)

par Gabriel LeMarié - 25 février 2014

In this Talk, first we discuss the possibility of novel phases of matter for bosons induced by artificial gauge fields. We address the possibility of bosonic chiral Mott phases, where bosons are in a Mott phase and at the same time exhibit non-trivial chiral edge modes as a result of a uniform magnetic field or artificial gauge fields. We will show that these phases can appear in simple bosonic ladder systems and in two dimensions. We will also study non-trivial topological phases on the Kagome and honeycomb lattices. Second, realizing these phases in ultra-cold systems or photon systems often requires the introduction of time-dependent AC potentials in the presence of interaction effects. We summarize our recent effort in this direction to describe driven and interacting systems, in relation with stochastic approaches.
