Multibath Influence Matrices: Universal Scaling from Real-Time Dynamics
Matan Lotem, Michael Sonner, Valentin Link +2
Diverging timescales are the hallmark of critical dynamics and the bottleneck to their classical and quantum simulation. To tame this, we compress a spacetime tensor network: tempo…
Steady-state dynamical mean field theory based on influence functional matrix product states
Mithilesh Nayak, Julian Thoenniss, Michael Sonner +2
We implement the recently developed influence functional matrix product states approach as impurity solver in equilibrium and nonequilibrium dynamical mean field theory (DMFT) calc…
Semi-group influence matrices for non-equilibrium quantum impurity models
Michael Sonner, Valentin Link, Dmitry A. Abanin
We introduce a framework for describing the real-time dynamics of quantum impurity models out of equilibrium which is based on the influence matrix approach. By replacing the dynam…
Efficient Pseudomode Representation and Complexity of Quantum Impurity Models
Julian Thoenniss, Ilya Vilkoviskiy, Dmitry A. Abanin
Out-of-equilibrium fermionic quantum impurity models (QIM), describing a small interacting system coupled to a continuous fermionic bath, play an important role in condensed matter…
