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 …

While basic features of polarons were well recognized a long time ago and have been
described in a number of review papers and textbooks, interest in the role of electron …

The optical-conductivity profile carries information on electronic dynamics in interacting
quantum many-body systems. Its computation is a formidable task that is usually …

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 …

We present a theory that efficiently describes the quantum dynamics of an electronic
excitation that is coupled to a continuous, highly structured phonon environment. Based on a …

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 …
