Imaginary-time matrix product state impurity solver for dynamical mean-field theory
F. Alexander Wolf, Ara Go, Ian P. McCulloch +2
We present a new impurity solver for dynamical mean-field theory based on imaginary-time evolution of matrix product states. This converges the self-consistency loop on the imagina…
How to discretize a quantum bath for real-time evolution
Ines de Vega, Ulrich Schollwöck, F. Alexander Wolf
Many numerical techniques for the description of quantum systems that are coupled to a continuous bath require the discretization of the latter. To this end, a wealth of methods ha…
Dynamics of heat and mass transport in a quantum insulator
Mateusz Łącki, Dominique Delande, Jakub Zakrzewski
The real time evolution of two pieces of quantum insulators, initially at different temperatures, is studied when they are glued together. Specifically, each subsystem is taken as…
Solving nonequilibrium dynamical mean-field theory using matrix product states
F. Alexander Wolf, Ian P. McCulloch, Ulrich Schollwöck
We solve the nonequilibrium dynamical mean-field theory (DMFT) using matrix product states (MPS). This allows us to treat much larger bath sizes and by that reach substantially lon…
