Ultrafast optical spectroscopy of strongly correlated materials and high-temperature superconductors: a non-equilibrium approach
In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

The transient localization scenario for charge transport in crystalline organic materials
Charge transport in crystalline organic semiconductors is intrinsically limited by the
presence of large thermal molecular motions, which are a direct consequence of the weak …

Holstein polaron
We describe a variational method to solve the Holstein model for an electron coupled to
dynamical, quantum phonons on an infinite lattice. The variational space can be …

Density-matrix renormalization-group study of the polaron problem in the Holstein model
We propose a density-matrix renormalization-group (DMRG) approach to study lattices
including bosons. The key to the approach is an exact map** of a boson site containing 2 …

Dimensionality effects on the Holstein polaron
Based on a recently developed variational method, we explore the properties of the Holstein
polaron on an infinite lattice in D dimensions, where 1<~ D<~ 4. The computational method …

Comparative determinant quantum Monte Carlo study of the acoustic and optical variants of the Su-Schrieffer-Heeger model
We compare the acoustic Su–Schrieffer–Heeger (SSH) model with two of its optical variants
where the phonons are defined on either on the sites or bonds of the system. First, we …

Polaron solutions and normal-mode analysis in the semiclassical Holstein model
We investigate polaron properties in the semiclassical Holstein model in one, two, and three
dimensions, using two methods: a simple and efficient numerical scheme and a variational …
