Validity and Limits of Low Order Hybridization Expansion Approaches for Multi-Orbital Systems
Dolev Goldberger, Ido Zemach, Lei Zhang +4
Low-order hybridization expansion methods such as the non-crossing approximation (NCA) and the one-crossing approximation (OCA) are widely used impurity solvers in the study of str…
Transient Dynamical Phase Diagram of the Spin-Boson Model at Finite Temperature
Olga Goulko, Hsing-Ta Chen, Moshe Goldstein +1
We present numerically exact inchworm quantum Monte Carlo results for the real-time dynamics of the spin polarization in the sub-Ohmic spin-boson model at finite temperature. We fo…
Compact representation and long-time extrapolation of real-time data for quantum systems using the ESPRIT algorithm
Andre Erpenbeck, Yuanran Zhu, Yang Yu +6
Representing real-time data as a sum of complex exponentials provides a compact form that enables both denoising and extrapolation. As a fully data-driven method, the Estimation of…
Inchworm tensor train hybridization expansion quantum impurity solver
Yang Yu, André Erpenbeck, Dominika Zgid +3
The investigation of quantum impurity models plays a crucial role in condensed matter physics because of their wide-ranging applications, such as embedding theories and transport p…
Transient dynamical phase diagram of the spin-boson model
Olga Goulko, Hsing-Ta Chen, Moshe Goldstein +1
We investigate the real-time dynamics of the sub-Ohmic spin-boson model across a broad range of coupling strengths, using the numerically exact inchworm quantum Monte Carlo algorit…
Determinant- and Derivative-Free Quantum Monte Carlo Within the Stochastic Representation of Wavefunctions
Liam Bernheimer, Hristiana Atanasova, Guy Cohen
Describing the ground states of continuous, real-space quantum many-body systems, like atoms and molecules, is a significant computational challenge with applications throughout th…
Dynamical Mean Field Theory of the Bilayer Hubbard Model with Inchworm Monte Carlo
Dolev Goldberger, Yehonatan Fridman, Emanuel Gull +2
Dynamical mean-field theory allows access to the physics of strongly correlated materials with nontrivial orbital structure, but relies on the ability to solve auxiliary multi-orbi…
Numerically exact simulation of photo-doped Mott insulators
Fabian Künzel, André Erpenbeck, Daniel Werner +4
A description of long-lived photo-doped states in Mott insulators is challenging, as it needs to address exponentially separated timescales. We demonstrate how properties of such s…
