RIKEN Center for Emergent Matter Science (CEMS)
Quantum Many-Body Dynamics Research Unit


Modern technology has been progressed based on understanding of quantum many-body systems. In addition to the conventional study of equilibrium states, non-equilibrium dynamics plays an important role in developing further intriguing materials and advancing quantum information processing technology. In this research unit, we investigate non-equilibrium dynamics of quantum many-body systems using ultracold atomic gases. Advantages of ultracold-atom experiments are simplicity and excellent controllability of the parameters, including dimensions, of the systems. Especially, a quantum gas loaded into periodic potential generated by a laser (optical lattice) can mimic fundamental models in the strongly correlated physics, and it can be used as a platform for quantum information processing. Utilizing such systems, we investigate real-time and real-space dynamics, and also control the many-body dynamics.
