Optically active molecular materials, such as organic conjugated polymers and biological
systems, are characterized by strong coupling between electronic and vibrational degrees of …

Operational stability of perovskite solar cells (PSCs) is rapidly becoming one of the pressing
bottlenecks for their upscaling and integration of such promising photovoltaic technology …

The field-induced dynamics of polarons in armchair graphene nanoribbons (GNRs) is
theoretically investigated in the framework of a two-dimensional tight-binding model with …

A translation-invariant (TI) bipolaron theory of superconductivity based, like Bardeen–
Cooper–Schrieffer theory, on Fröhlich Hamiltonian is presented. Here the role of Cooper …

In this work we use gap-fitting procedure to tune the long-range corrected functionals and
accurately investigate the electronic and optical properties of the five main molecules …

A semi-empirical Holstein–Peierls model is used to study the temperature effects on the
polaron stability in organic semiconductors at a molecular scale. The approach takes into …

Graphene nanoribbons (GNRs) are two-dimensional structures with a rich variety of
electronic properties that derive from their semiconducting band gaps. In these materials …

High temperature superconducting theory drew controversy after the discovery of
superconductors at close to room temperatures. However, a consistent microscopic theory of …

By means of a 2-D tight-binding model with lattice relaxation in a first-order expansion, we
report different polaron properties depending on the armchair graphene nanoribbons width …

In this paper, we have investigated the lifetime, mobility and effective mass of polaron and
bipolaron in graphene under laser field by using the well-known Lee–Low–Pines …
