Ab initio path integral Monte Carlo simulations of the uniform electron gas on large length scales
Tobias Dornheim, Sebastian Schwalbe, Zhandos Moldabekov +2
The accurate description of non-ideal quantum many-body systems is of prime importance for a host of applications within physics, quantum chemistry, material science, and related d…
Fermionic physics from ab initio path integral Monte Carlo simulations of fictitious identical particles
Tobias Dornheim, Panagiotis Tolias, Simon Groth +3
The \emph{ab initio} path integral Monte Carlo (PIMC) method is one of the most successful methods in statistical physics, quantum chemistry and related fields, but its application…
Quantum version of the integral equation theory based dielectric scheme for strongly coupled electron liquids
Panagiotis Tolias, Federico Lucco Castello, Tobias Dornheim
A novel dielectric scheme is proposed for strongly coupled electron liquids that handles quantum mechanical effects beyond the random phase approximation level and treats electroni…
Unravelling the nonlinear ideal density response of many-body systems
Panagiotis Tolias, Tobias Dornheim, Zhandos A. Moldabekov +1
Nonlinear density response theory is revisited focusing on the harmonically perturbed finite temperature uniform electron gas. Within the non-interacting limit, brute force quantum…
Energy response and spatial alignment of the perturbed electron gas
Tobias Dornheim, Panagiotis Tolias, Zhandos Moldabekov +1
We present extensive new \emph{ab initio} path integral Monte Carlo (PIMC) simulations of the harmonically perturbed uniform electron gas (UEG) for different densities and temperat…
Extraction of the frequency moments of spectral densities from imaginary-time correlation function data
Tobias Dornheim, Damar C. Wicaksono, Juan E. Suarez-Cardona +5
We introduce an exact framework to compute the positive frequency moments of different dynamic properties from imaginary-time quantum Monte Carlo…
