Our Researches
Based on the symbiotic relation between developing quantum many-body algorithms and extending knowledge on emergent physics, we aim to provide the numerically exact results on the long-standing problems of strongly correlated systems, including the unconventional superconductors, frustrated spin systems, and light-matter-coupled systems. We have expertise in the quantum Monte Carlo methods, the dynamical mean-field theory, and the Feynman diagrammatic theory.
