Exact diagonalization of a non-quadratic bosonic Liouvillian with two-body loss
Masaaki Tokieda
We present the full diagonalization of a non-quadratic bosonic Liouvillian with a two-body loss term. The Liouvillian is shown to be exactly diagonalizable in terms of left and rig…

Testing bath correlation functions for open quantum dynamics simulations
Masaaki Tokieda
Accurate simulations of thermalization in open quantum systems require a reliable representation of the bath correlation function (BCF). Numerical approaches, such as the hierarchi…

Work-minimizing protocols in driven-dissipative quantum systems: An impulse-ansatz approach
Masaaki Tokieda
The second law of thermodynamics sets a lower bound on the work required to drive a system between thermal equilibrium states, with equality attained in the quasistatic limit. For…
