We present a highly efficient yet accurate analytical approximation for the Green's function of
a Holstein polaron. It is obtained by summing all the self-energy diagrams, but with each self …

A comprehensive picture of polaron and bipolaron physics is essential to understand the
optical absorption spectrum in many materials with electron-phonon interactions. In …

We study static and dynamic properties of an electron coupled to dispersive quantum optical
phonons in the framework of the Holstein model defined on a one-dimensional lattice …

Based on the canonical Lang-Firsov transformation of the Hamiltonian we develop a very
efficient quantum Monte Carlo algorithm for the Holstein model with one electron …

We study the real-time dynamics of a highly excited charge carrier coupled to quantum
phonons via a Holstein-type electron-phonon coupling. This is a prototypical example for the …

We present the first unbiased results for the mobility μ of a one-dimensional Holstein polaron
obtained by numerical analytic continuation combined with diagrammatic and worldline …

We explore the ground state and thermodynamic properties of the polaron coupled to
quantum dispersive optical phonons in one spatial dimension. Calculations are performed …

Numerical methods whereby exact solutions to the problem of a few particles interacting with
one another and with several bosonic excitation branches are presented. The diagrammatic …

The ever-growing intersection of quantum electrodynamics (QED) and molecular processes
has shown remarkable and unanticipated advancements in altering molecular properties …

We present a density-matrix embedding theory (DMET) study of the one-dimensional
Hubbard–Holstein model, which is paradigmatic for the interplay of electron–electron and …
