The unit of Collective Dynamics and Quantum Transport reveals dynamical and transport phenomena in various forms of quantum matter, from quantum and topological materials to synthetic quantum matter and hybrid quantum platforms, to explore emergent many-body dynamics and propose their spintronic, electronic, and quantum-information functionalities. We employ a combination of analytical and numerical theories. Current research focus mainly involves thermal and spin transport in quantum magnets and out-of-equilibrium spin dynamics relevant to pump-probe experiments. We are also exploring the interdisciplinary field of condensed matter physics and quantum optics, in particular between spintronics and photonics, to uncover intriguing dissipative dynamical behaviors.
