Quantum Gases

We have modelled Pyragas’ time-delay auto-synchronization feedback control applied to a quantum system. For a topical cavity QED many-body system, the Dicke model as realized in recent experiments, we have investigated in what manner a feedback forc…

Rapid Steady State Convergence for Quantum Systems Using Time-Delayed…

We propose a time-delayed feedback control scheme for open quantum systems that can dramatically reduce the time to reach steady state. No measuremen…

Tree models for difference and change detection in a complex environm…

A new family of tree models is proposed, which we call "differential trees." A differential tree model is constructed from multiple data sets and aim…
