Many-Body Echo with Driven Atomic Condensates and Application to Matterwave Interferometery

Abstract

The first goal is to investigate the quantum nature of heating in a Floquet system. Heating is one of the dominant sources of dissipation and decoherence in driven many-body systems. Theoretically, however, a coherent modulation should not increase the entropy of the system. I propose a precise amplitude/phase control of the modulation that can limit and even counteract the proliferation of thermal excitations. Numerical optimization shows that an ideal control of the modulation waveform can reverse as much as 80% of the observed heating.
