Maxwell’s Demon, ‘a being whose faculties are so sharpened that he can follow every molecule in its course’, has been the centre of much debate about its abilities to violate the second law of thermodynamics. Landauer’s hypothesis, that the Demon must erase its memory and incur a thermodynamic cost, has become the standard response to Maxwell’s dilemma, and its implications for the thermodynami...

We investigate topological and disorder effects in non-Hermitian systems with chiral symmetry. The system under consideration consists a finite Su-Schrieffer-Heeger chain to which two semi-infinite leads are attached. lacks the parity-time time-reversal symmetries is appropriate for study of quantum transport properties. complex energy spectrum analyzed terms chain-lead coupling strength, shows...

The erasure of a classical bit of information is a dissipative process. The minimum heat produced during this operation has been theorized by Rolf Landauer in 1961 to be equal to kBT ln2 and takes the name of Landauer limit, Landauer reset or Landauer principle. Despite its fundamental importance, the Landauer limit remained untested experimentally for more than fifty years until recently when ...

In this paper we address the topic of inelastic electron scattering in mesoscopic quantum transport. For systems where only elastic scattering is present, Landauer theory provides an adequate description of transport that relates the electronic current to single-particle transmission and reflection probabilities. A formalism proposed recently by Bonc̆a and Trugman facilitates the calculation of ...

We study the quantum noise of the electronic current in a double-barrier system with a single resonant level. In the framework of the Landauer formalism, we treat the double barrier as a quantum coherent scattering region that can exchange photons with a coupled electric field, e.g., a laser beam or a periodic ac bias voltage. As a consequence of the manifold parameters that are involved in thi...

Hybrid structures based on graphene and carbon nanotubes (CNTs) are one of the most relevant modern nanomaterials for applications in various fields, including electronics. The variety topological architectures graphene/CNT hybrids requires a preliminary study their physical properties by silico methods. This paper is devoted to electronic electrical hybrid 2D with an island topology using self...
