A Scale-Shape Dual Newton Method for Entropic Least Squares
Nicholas Barnfield, James V. Burke, Michael P. Friedlander +1
We give a damped inexact Newton method for entropy-regularized least-squares on the nonnegative orthant that converges globally at a linear rate with iteration comp…
The noiseless limit and improved-prior limit of the maximum entropy method and their implications for the analytic continuation problem
Thomas Chuna, Nicholas Barnfield, Paul Hamann +3
Quantum Monte Carlo (QMC) methods are uniquely capable of providing exact simulations of quantum many-body systems. Unfortunately, the applications of a QMC simulation are limited…
Estimates of the dynamic structure factor for the finite temperature electron liquid via analytic continuation of path integral Monte Carlo data
Thomas Chuna, Nicholas Barnfield, Jan Vorberger +3
Understanding the dynamic properties of the uniform electron gas (UEG) is important for numerous applications ranging from semiconductor physics to exotic warm dense matter. In thi…
Dual formulation of the maximum entropy method applied to analytic continuation of quantum Monte Carlo data
Thomas Chuna, Nicholas Barnfield, Tobias Dornheim +2
Many fields of physics use quantum Monte Carlo techniques, but struggle to estimate dynamic spectra via the analytic continuation of imaginary-time quantum Monte Carlo data. One of…
