Exploring Unsolved Physical Phenomena—Quantum many-body physics with ultracold atomic gases Shun Uchino,  Assistant Professor

Research Topic

Quantum Transport Phenomena with Strongly Interacting Cold Atomic Gases

I am interested in emergent properties of many-body systems, which consist of quantum mechanical degrees of freedom. The systems are known as quantum many-body systems and are of importance to understand ubiquitous phenomena such as superconductivity and magnetism. Especially, I am interested in behaviors of such systems in nonequilibrium. By means of cold atomic gases, I conduct studies on mesoscopic transport and open quantum systems.
