Ab Initio Polaron Wave Functions
Paul J. Robinson, Joonho Lee, Ankit Mahajan +1
In this work we demonstrate that accurate ground state wave functions may be constructed for polarons in a fully ab initio setting across the wide range of couplings associated wit…
Structure and dynamics of electron-phonon coupled systems using neural quantum states
Ankit Mahajan, Paul J. Robinson, Joonho Lee +1
In this work, we use neural quantum states (NQS) to describe the high-dimensional wave functions of electron-phonon coupled systems. We demonstrate that NQS can accurately and syst…
Tensor network influence functionals in the continuous-time limit: connections to quantum embedding, bath discretization, and higher-order time propagation
Gunhee Park, Nathan Ng, David R. Reichman +1
We describe two developments of tensor network influence functionals (in particular, influence functional matrix product states (IF-MPS)) for quantum impurity dynamics within the f…
Competing Generalized Wigner Crystal States in Moiré Heterostructures
Shu Fay Ung, Joonho Lee, David R. Reichman
We present a comprehensive study of generalized Wigner crystals across various filling factors for system sizes up to 162 holes employing Hartree-Fock theory and explicitly correla…
Real time evolution of Anderson impurity models via tensor network influence functionals
Nathan Ng, Gunhee Park, Andrew J. Millis +2
In this work we present and analyze two tensor network-based influence functional approaches for simulating the real-time dynamics of quantum impurity models such as the Anderson m…
Strongly correlated ladders in K-doped -terphenyl crystals
John Sous, Natalia A. Gadjieva, Colin Nuckolls +2
Potassium-doped terphenyl has recently attracted attention as a potential host for high-transition-temperature superconductivity. Here, we elucidate the many-body electronic struct…
