Deciphering quantum fingerprints in electric conductance
Nature Communications, 2022 Scattering of electrons from defects and boundaries in mesoscopic samples is encoded in quantum interference patterns of magneto-conductance, but these patterns are difficult to interpret.

Quantum conductance and electrical resistivity [PDF]
Physics Letters A, 2006 The Landauer formula for quantum conductance, based on the modern paradigm: "conduction is transmission", is generalized to samples of macroscopic size. Two regimes of electrical conduction, namely diffusive and ballistic ones, are studied. In the former regime, Drude's formula for the electrical resistivity is recovered and it is found a maximum ...

Quantum Hall Conductivity in the Presence of Interactions [PDF]
Symmetry, 2020 We discuss quantum Hall effect in the presence of arbitrary pair interactions between electrons. It is shown that, irrespective of the interaction strength, the Hall conductivity is given by the filling fraction of Landau levels averaged over the ground state of the system.

Conductance Peaks in Open Quantum Dots [PDF]
Physical Review Letters, 2011 We present a simple measure of the conductance fluctuations in open ballistic chaotic quantum dots, extending the number of maxima method originally proposed for the statistical analysis of compound nuclear reactions. The average number of extreme points (maxima and minima) in the dimensionless conductance, $T$, as a function of an arbitrary external ...

Conductance of Fully Equilibrated Quantum Wires [PDF]
Physical Review Letters, 2009 We study the conductance of a quantum wire in the presence of weak electron-electron scattering. In a sufficiently long wire the scattering leads to full equilibration of the electron distribution function in the frame moving with the electric current. At non-zero temperature this equilibrium distribution differs from the one supplied by the leads.

Fluctuation Theorem in Quantum Heat Conduction [PDF]
Physical Review Letters, 2007 We consider steady state heat conduction across a quantum harmonic chain connected to reservoirs modelled by infinite collection of oscillators. The heat, $Q$, flowing across the oscillator in a time interval $τ$ is a stochastic variable and we study the probability distribution function $P(Q)$.

Quantum Interference Effects in Quantum Dot Molecular With Majorana Bound States
Frontiers in Physics, 2021 Non-invasive detection of the Majorana bound state (MBSs), a kind of quasiparticle without charge and mass, is one of the core issues in current condensed matter physics.

The Effect of Anchor Group on the Phonon Thermal Conductance of Single Molecule Junctions
Applied Sciences, 2021 There is a worldwide race to convert waste heat to useful energy using thermoelectric materials. Molecules are attractive candidates for thermoelectricity because they can be synthesised with the atomic precision, and intriguing properties due to quantum

Spin Conductance of the Quantum Wire [PDF]
Acta Physica Polonica A, 2006 The electron spin transport along a semiconducting quantum wire connected to spin-unpolarized electron reservoirs and the spin ltering properties of the wire are investigated. The wire is immersed in a magnetic eld that is perpendicular to the wire axis and substrate plane on which the wire is grown.
