Imaginary-Time Matrix Product State Impurity Solver for Dynamical Mean-Field Theory
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 imaginary-frequency axis and obtains real-frequency information in a final real-time evolution. Relative to computations on the...
