Research
I am interested in topics broadly related to computational quantum many-body problems. Currently I mainly work on theories, simulations and algorithmic applications of dissipative dynamics.

C³L (Coupled-Cluster Coupled Lindblad)
C³L (Coupled-Cluster Coupled Lindblad, “C cubed L”) applies coupled-cluster theory to non-Markovian impurity dynamics. By representing bath memory with coupled Lindblad pseudomodes, it provides a scalable route to correlated steady states, dynamical Green functions, spectra, and nonequilibrium transport in multiorbital systems with general two-body interactions.
