In this paper, we present the differential master equation (or Liouville–Von​ Neumann
equation) for a harmonic oscillator with position-dependent mass (PDM) exposed to a …

We study the proximity-induced superconducting state in a general bilayer–conventional s-
wave superconductor hybrid structure. For the bilayer we include a general parabolic …

In this paper we study the effects of hybridization in the superconducting properties of a two-
band system. We consider the cases that these bands are formed by electronic orbitals with …

Topological superconductivity in multiband systems has received much attention due to a
variety of possible exotic superconducting order parameters as well as nontrivial bulk and …

The study of Majorana fermions is of great importance for the implementation of a quantum
computer. These modes are topologically protected and very stable. It is now well known …

We explore the temperature effects in the superconducting phases of a hybridized two-band
system. We show that for zero hybridization between the bands, there are two different …

The study of multi-band superconductivity is relevant for a variety of systems, from ultra-cold
atoms with population imbalance to particle physics and condensed matter. As a …

The importance of models with an exact solution for the study of materials with non-trivial
topological properties has been extensively demonstrated. The Kitaev model plays a …

Superconductivity in strongly correlated systems is a remarkable phenomenon that attracts
huge interest. The study of this problem is relevant for materials such as the high T c oxides …

Realistic implementations of the Kitaev chain require, in general, the introduction of extra
internal degrees of freedom. In the present work, we discuss the presence of hidden BDI …
