The Quantum Tunneling of Ions Model Can Explain the Pathophysiology of Tinnitus

open access: yesBrain Sciences, 2022
Tinnitus is a well-known pathological entity in clinical practice. However, the pathophysiological mechanisms behind tinnitus seem to be elusive and cannot provide a comprehensive understanding of its pathogenesis and clinical manifestations.

Enhanced thermoelectric properties in boron nitride quantum-dot

open access: yesResults in Physics, 2017
We have investigated the ballistic thermoelectric properties in boron nitride quantum dots by using the nonequilibrium Green’s function approach and the Landauer transport theory.

Tunneling magnetoresistance calculation for double quantum dot connected in parallel shape to ferromagnetic Leads

open access: yesJournal of Kufa-Physics, 2023
In this paper, a theoretical model for electron transport through symmetric system consisting of two baths interferometer with one single-level quantum dot in each of its arms was considered.

Classical and quantum conductivity in β-Ga2O3 [PDF]

open access: yesScientific Reports, 2019
AbstractThe conductivity σ, quantum-based magnetoconductivity Δσ = σ(B) − σ(0), and Hall coefficient RH (= µH/σ) of degenerate, homoepitaxial, (010) Si-doped β-Ga2O3, have been measured over a temperature range T = 9–320 K and magnetic field range B = 0–10 kG. With ten atoms in the unit cell, the normal-mode phonon structure of β-Ga2O3 is very complex,

Comparing conductance quantization in quantum wires and quantum Hall systems [PDF]

open access: yesPhysical Review B, 1996
We propose a new calculation of the DC conductance of a 1-dimensional electron system described by the Luttinger model. Our approach is based on the ideas of Landauer and Büttiker and on the methods of current algebra. We analyse in detail the way in which the system can be coupled to external reservoirs.

Electron transfer and conductance quantum

open access: yesPhysical Chemistry Chemical Physics, 2020
The relationship between the quantum capacitance and the conductance quantum gives rise to a quantum mechanical equation that encompasses the theory of electron transfer rate proposed by Rudolph Marcus.

Conductance microscopy of quantum dots weakly or strongly coupled to the conducting channel

open access: yesNew Journal of Physics, 2014
We consider scanning gate conductance microscopy of an open quantum dot that is connected to the conducting channel using the wave function description of the quantum transport and a finite difference approach.

Dynamical Coulomb blockade under a temperature bias

open access: yesPhysical Review Research, 2021
We observe and comprehend the dynamical Coulomb blockade suppression of the electrical conductance across an electronic quantum channel subjected to a temperature difference. A broadly tunable, spin-polarized Ga(Al)As quantum channel is connected on-chip,
