Unified time analysis of photon and (nonrelativistic) particle Tunnelling, and the Superluminal group-velocity problem [PDF]

, 2001
A unified approach to the time analysis of tunnelling of nonrelativistic particles is presented, in which Time is regarded as a quantum-mechanical observable, canonically conjugated to Energy.

Sensing the quantum limit in scanning tunnelling spectroscopy

Nature Communications, 2016
The tunnelling current in scanning tunnelling spectroscopy has often been treated by a continuous charge flow, which lacks proper treatment of charge quantization. Here, Ast et al.

Tunnelling series in terms of perturbation theory for quantum spin systems [PDF]

, 1999
Considered is quantum tunnelling in anisotropic spin systems in a magnetic field perpendicular to the anisotropy axis. In the domain of small field the problem of calculating tunnelling splitting of energy levels is reduced to constructing the ...

Fermi edge singularities in transport through lateral GaAs quantum dots

New Journal of Physics, 2017
We measure tunnelling currents through electrostatically defined quantum dots in a GaAs/AlGaAs heterostructure connected to two leads. For certain tunnelling barrier configurations and high sample bias we find a pronounced resonance associated with a ...

Quantum suppression of chaotic tunnelling [PDF]

Journal of Physics A: Mathematical and Theoretical, 2007
The interplay between chaotic tunneling and dynamical localization in mixed phase space is investigated. Semiclassical analysis using complex classical orbits reveals that tunneling through torus regions and transport in chaotic regions are not independent processes, rather they are strongly correlated and described by complex orbits with both ...

Microwave-induced conductance replicas in hybrid Josephson junctions without Floquet—Andreev states

Nature Communications, 2023
Light–matter coupling allows control and engineering of complex quantum states. Here we investigate a hybrid superconducting–semiconducting Josephson junction subject to microwave irradiation by means of tunnelling spectroscopy of the Andreev bound state

Quantum Corrected Non-Thermal Radiation Spectrum from the Tunnelling Mechanism

Galaxies, 2015
The tunnelling mechanism is today considered a popular and widely used method in describing Hawking radiation. However, in relation to black hole (BH) emission, this mechanism is mostly used to obtain the Hawking temperature by comparing the probability ...

Large effects from small QCD instantons: making soft bombs at hadron colliders

Journal of High Energy Physics, 2020
It is a common belief that the last missing piece of the Standard Model of particles physics was found with the discovery of the Higgs boson at the Large Hadron Collider.

Addressing student models of energy loss in quantum tunnelling

, 2005
We report on a multi-year, multi-institution study to investigate student reasoning about energy in the context of quantum tunnelling. We use ungraded surveys, graded examination questions, individual clinical interviews, and multiple-choice exams to ...
