Engineering many-body quantum states and dissipative dynamics in quantum simulators
Abstract
Experiments with ultracold atomic and molecular gases have developed to the point where these systems can be used as quantum emulators. With first-principles knowledge of the underlying microscopic physics, and full control over both energy potential landscapes and inter-particle interactions, these experiments allow us to simulate – and gain new insight into – a wide range of fundamental behavior from many-particle quantum systems. Beyond fundamental insight, the understanding we gain has important potential consequences for new technologies, including in advancing materials engineering, and developing next generations of devices for high-precision sensing and measurement.A key current challenge for quantum emulators is cooling the systems to lower temperatures, in order to access a new range of quantum many-body states, as well as a variety of phenomena in out-of-equilibrium dynamics. In this project, we will develop new tools to address this problem, as well as new fundamental understanding over the role of dissipation in these systems. We will begin by investigating the use of adiabatic cooling processes and the isolation of entropy reservoirs to cool magnetic and motional states of ultracold atoms in optical lattices, with applications to frustrated magnetic states, SU(N) symmetric systems with group-II atoms, and polar molecules with long-range interactions. This part is designed to have direct applications to ongoing experiments and to help set a short-time roadmap for the realization of certain novel many-body phases. We will extend these studies to time-dependent dynamics induced by engineered dissipation, and also connect our results to quantum networks – including arrays of trapped atoms and quantum dots coupled to photonic waveguides. Each part of the project will be supported by further development of numerical techniques for simulating dissipative quantum dynamics and for applying quantum control techniques to realistic experimental conditions.
