Polarons are quasiparticles that easily form in polarizable materials due to the coupling of
excess electrons or holes with ionic vibrations. These quasiparticles manifest themselves in …

We report multipronged progress on the stochastic averaging approach to numerical
analytic continuation of imaginary-time correlation functions computed by quantum Monte …

Numerical results for ground-state and excited-state properties (energies, double
occupancies, and Matsubara-axis self-energies) of the single-orbital Hubbard model on a …

Matter at extreme temperatures and pressures—commonly known as warm dense matter
(WDM)—is ubiquitous throughout our Universe and occurs in astrophysical objects such as …

Ab initio calculations of the phonon-induced band structure renormalization are currently
based on the perturbative Allen-Heine theory and its many-body generalizations. These …

Simulations of finite temperature quantum systems provide imaginary frequency Green's
functions that correspond one to one to experimentally measurable real-frequency spectral …

Oxygen vacancies created in anatase TiO 2 by UV photons (80–130 eV) provide an effective
electron-do** mechanism and induce a hitherto unobserved dispersive metallic state …

Electronic and optical properties of materials are affected by atomic motion through the
electron–phonon interaction: not only band gaps change with temperature, but even at …

It is remarkable how the Fröhlich polaron, one of the simplest examples of a Quantum Field
Theoretical problem, as it basically consists of a single fermion interacting with a scalar Bose …

A detailed description is provided of a new worm algorithm, enabling the accurate
computation of thermodynamic properties of quantum many-body systems in continuous …
