Exact master equation for generalized quantum Brownian motion with momentum-dependent system-environment couplings
In this paper we generalize the quantum Brownian motion (QBM) to include the momentum-dependent system-environment couplings. The resulting Hamiltonian in the particle number representation is given by H_{t}ot=ℏω_{S}a^{†}a+∑_{k}ℏω_{k}b_{k}^{†}b_{k}+∑_{k}ℏ(V_{k}a^{†}b_{k}+V_{k}^{*}b_{k}^{†}a)+∑_{k}ℏ(...
