Fast Tensor Network Imaginary Time Evolution by Implicit Stepping on Logarithmic Grids
John P. Zima, E. Miles Stoudenmire, Steven R. White +2
We present a new method for the efficient imaginary time evolution of quantum many-body wavefunctions represented by matrix product states (MPS). We first show that logarithmic tim…
Finite-temperature formation of magnetic plateaus and simplex liquid states on the frustrated ruby lattice
Antonio Francesco Mello, E. Miles Stoudenmire, Joseph Tindall
Geometric frustration in quantum systems can stabilize unconventional phases of matter that avoid traditional magnetic ordering at low temperatures. Here, we observe this phenomeno…
Finite Temperature Minimal Entangled Typical Thermal States Impurity Solver
Xiaodong Cao, E. Miles Stoudenmire, Olivier Parcollet
We present a minimally entangled typical thermal state (METTS) quantum impurity solver for general multi-orbital systems at finite temperatures. We introduce an improved estimator…
Dynamical correlation functions from complex time evolution
Xiaodong Cao, Yi Lu, E. Miles Stoudenmire +1
We present an approach to tame the growth of entanglement during time evolution by tensor network methods. It combines time evolution in the complex plane with a perturbative and c…
Equilibrium Quantum Impurity Problems via Matrix Product State Encoding of the Retarded Action
Benedikt Kloss, Julian Thoenniss, Michael Sonner +6
In the dimensional imaginary-time path integral formulation of quantum impurity problems, the retarded action encodes the hybridization of the impurity with the bath. In this…
Matrix Product Study of Spin Fractionalization in the 1D Kondo Insulator
Jing Chen, E. Miles Stoudenmire, Yashar Komijani +1
The Kondo lattice is one of the classic examples of strongly correlated electronic systems. We conduct a controlled study of the Kondo lattice in one dimension, highlighting the ro…
