Half-integer thermal conductance in integer quantum Hall states [PDF]

Nature Communications
Considering a range of candidate quantum phases of matter, half-integer thermal conductance is believed to be an unambiguous evidence of non-Abelian states.

Anomalous conductance quantization of a one-dimensional channel in monolayer WSe2

npj 2D Materials and Applications, 2023
Among quantum devices based on 2D materials, gate-defined quantum confined 1D channels are much less explored, especially in the high-mobility regime where many-body interactions play an important role.

Proton Quantum Tunneling: Influence and Relevance to Acidosis-Induced Cardiac Arrhythmias/Cardiac Arrest

Pathophysiology, 2021
Acidosis and its associated pathologies predispose patients to develop cardiac arrhythmias and even cardiac arrest. These arrhythmias are assumed to be the result of membrane depolarization, however, the exact mechanism of depolarization during acidosis ...

Investigations of Optical Coulomb Blockade Oscillations in Plasmonic Nanoparticle Dimers

International Journal of Photoenergy, 2022
The exploration of Coulomb blockade oscillations in plasmonic nanoparticle dimers is the subject of this study. When two metal nanoparticles are brought together at the end of their journey, tunnelling current prevents an infinite connection dipolar ...

Quantum interference effects in multi-channel correlated tunneling structures

Scientific Reports, 2021
In multi-channel tunneling systems quantum interference effects modify tunneling conductance spectra due to Fano effect. We investigated the impact of Hubbard type Coulomb interaction on tunneling conductance spectra for the system formed by several ...

3D quantum Hall effect in a topological nodal-ring semimetal

Quantum Frontiers, 2023
A quantized Hall conductance (not conductivity) in three dimensions has been searched for more than 30 years. Here we explore it in 3D topological nodal-ring semimetals, by employing a minimal model describing the essential physics.
