Quantum Systems

Open Quantum Systems (Dr Ahsan Nazir)

All quantum systems are open, meaning that they evolve under the influence of their surroundings, rather than in isolation. Our research is focussed on understanding the delicate interplay of quantum coherence and noise that exists in such situations. We are developing a number of innovative theoretical methods to model open quantum systems beyond common approximations, with a particular interest in cases in which system-environment interactions are strong, resulting in the generation of substantial mutual correlations. By building on the idea of redrawing the boundary between system and environment, we are exploring methods to develop an efficient framework in which to study both the equilibrium and non-equilibrium dynamics of many-body open quantum systems, beyond perturbative regimes. We are also pursuing applications in diverse areas ranging from solid-state quantum information processing to quantum biology.‌
