Uncovering nonperturbative dynamics of the biased sub-Ohmic spin-boson model with variational matrix product states

We study the dynamics of the biased sub-Ohmic spin-boson model by means of a time-dependent variational matrix product state (TDVMPS) algorithm. The evolution of both the system and the environment is obtained in the weak- and the strong-coupling regimes, respectively characterized by damped spin os...
