Dissipative Tunneling

I am interested in quantum dynamics of nanoscale and atomic systems strongly coupled to the environment, such as quantum dots, Josephson junctions, molecular magnets, quantum diffusion, etc. My second field is quantum and classical Monte Carlo simulations to study new phases of matter, exotic phase transitions, and/or developing numerical tools for efficient simulations of realistic systems.
