A map of high-mobility molecular semiconductors
The charge mobility of molecular semiconductors is limited by the large fluctuation of intermolecular transfer integrals, often referred to as off-diagonal dynamic disorder, which causes transient localization...

Open AccessLow energy neutron production by inverse β decay in metallic hydride surfaces
It has recently been argued that inverse-β nuclear transmutations might occur at an impressively high rate in a thin layer at a metallic hydride surface under specific conditions. In this note we present a calcul...

A density matrix approach to the dynamical properties of a two-site Holstein model
The two-site Holstein model represents a first non-trivial paradigm for the interaction between an itinerant charge with a quantum oscillator, a very common topic in different ambits. Exact results can be achi...

Tunable Fröhlich polarons in organic single-crystal transistors
In organic field-effect transistors (FETs), charges move near the surface of an organic semiconductor, at the interface with a dielectric. In the past, the nature of the microscopic motion of charge carriers—w...

The Small Polaron Crossover: Role of Dimensionality
The crossover from quasi-free electron to small polaron in the Holstein model for a single electron is studied by means of both exact and self-consistent calculations in one dimension (1D) and on an infinite c...

The Charge-Ordered State from Weak to Strong Coupling
We apply the dynamical mean field theory to the problem of charge ordering. In the normal state as well as in the charge-ordered (CO) state, the existence of polarons (i.e., electrons strongly coupled to local...
