Tunneling theory for a bilayer graphene quantum dot’s single- and two-electron states

open access: yesNew Journal of Physics, 2022
The tuneability and control of quantum nanostructures in two-dimensional materials offer promising perspectives for their use in future electronics. It is hence necessary to analyze quantum transport in such nanostructures.

Slepian eigenvalues as tunnelling rates [PDF]

open access: yes, 2023
We calculate the eigenvalues of an integral operator associated with Prolate Spheroidal Wave Functions (or Slepian functions) by interpreting them as tunnelling probabilities in an analogous quantum problem.

A liénard oscillator resonant tunnelling diode-laser diode hybrid integrated circuit: model and experiment [PDF]

open access: yes, 2008
We report on a hybrid optoelectronic integrated circuit based on a resonant tunnelling diode driving an optical communications laser diode. This circuit can act as a voltage controlled oscillator with optical and electrical outputs.

Computational multiqubit tunnelling in programmable quantum annealers

open access: yesNature Communications, 2016
Quantum tunnelling may be advantageous for quantum annealing, but multiqubit tunnelling has not yet been observed or characterized theoretically.

Electrical detection and modulation of magnetism in a Dy-based ferroelectric single-molecule magnet

open access: yesNature Communications, 2023
Electrical control of magnetism in single-molecule magnets with peculiar quantum magnetic behaviours has promise for applications in molecular electronics and quantum computing. Nevertheless, such kind of magnetoelectric effects have not been achieved in

Quantum tunneling and trace anomaly [PDF]

open access: yesPhysics Letters B, 2009
We compute the corrections, using the tunneling formalisim based on a quantum WKB approach, to the Hawking temperature and Bekenstein-Hawking entropy for the Schwarzschild black hole. The results are related to the trace anomaly and are shown to be equivalent to findings inferred from Hawking's original calculation based on path integrals using zeta ...

Cooperative quantum information erasure [PDF]

open access: yesQuantum, 2023
We demonstrate an information erasure protocol that resets $N$ qubits at once. The method displays exceptional performances in terms of energy cost (it operates nearly at Landauer energy cost $kT \ln 2$), time duration ($\sim \mu s$) and erasure success ...
