Finite-temperature Green's function cluster expansion from thermofield doubles: Breakdown of the polaron picture
M. R. Carbone, S. Fomichev, B. Kloss +4
We introduce a method, numerically exact in principle, for computing the momentum- and frequency-resolved single-particle Green's function of a polaron at finite temperature. The m…
Self-consistent GW theory for superconductivity in SrTiO3 models
Zhi-Hao Cui, John Sous, Andrew J. Millis +1
Superconductivity in doped SrTiO occurs over a wide range of carrier densities, including those for which the Fermi energy is below the polar longitudinal optical phonon scale.…
Study of the triangular-lattice Hubbard model with constrained-path quantum Monte Carlo
Shu Fay Ung, Ankit Mahajan, David R. Reichman
We benchmark constrained-path Monte Carlo (CPMC) on the triangular-lattice Hubbard model for several fillings and values and show that symmetry-adapted trial wave functions sub…
Microscopic Phase-Field Modeling
Jaehyeok Jin, David R. Reichman
Phase-field methods offer a versatile computational framework for simulating large-scale morphological evolution. However, the applicability and predictability of phase-field model…
Evaluating Multiconfigurational Trials for Accurate Phaseless Auxiliary-Field Quantum Monte Carlo on 3d Transition Metal Complexes
Hung T. Vuong, Ankit Mahajan, John L. Weber +3
In this study, we evaluate multi-configurational trial wave function protocols for phaseless auxiliary field quantum Monte Carlo (ph-AFQMC) on transition metal containing systems.…
Field-Theoretic Simulation of Dean-Kawasaki Dynamics for Interacting Particles
Jaehyeok Jin, Chen Liu, David R. Reichman
The formulation of a fluctuating hydrodynamic theory for interacting particles is a crucial step in the theoretical description of liquids. The microscopic mappings proposed decade…
