Dissipation and decoherence effects in quantum systems

When a quantum system is connected to an environment, it experiences dissipation and decoherence effects, which affect the measurement of system observables. The theoretical modelling of quantum system requires complex techniques and formalisms. In particular, we investigate:

• Markov approach to Lindblad scattering superoperators to ensure positivity of the system density matrix
• Nonlocal scattering in the Wigner function formalism
• Interplay between energy dissipation and reservoir-induced thermalization in nonequilibrium quantum nanodevices
