RESEARCH SUMMARY
One of our main focuses is to develop state-of-the-art numerical methods such as quantum Monte Carlo methods and tensor network methods including the density matrix renormalization method for simulating ground states as well as quantum dynamics of strongly correlated quantum systems. We are also interested in developing quantum algorithms for quantum many-body systems and quantum computing simulations using classical computers such as Supercomputer Fugaku, as a ground challenge of information science in quest of a new computing paradigm.
