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…

First principles simulations of dense hydrogen
Michael Bonitz, Jan Vorberger, Mandy Bethkenhagen +24
Accurate knowledge of the properties of hydrogen at high compression is crucial for astrophysics (e.g. planetary and stellar interiors, brown dwarfs, atmosphere of compact stars) a…

Excitation signatures of isochorically heated electrons in solids at finite wavenumber explored from first principles
Zhandos A. Moldabekov, Thomas D. Gawne, Sebastian Schwalbe +3
Ultrafast heating of solids with modern X-ray free electron lasers (XFELs) leads to a unique set of conditions that is characterized by the simultaneous presence of heated electron…
