First Detection and Tunneling Time of a Quantum Walk

open access: yesEntropy, 2023
We consider the first detection problem for a one-dimensional quantum walk with repeated local measurements. Employing the stroboscopic projective measurement protocol and the renewal equation, we study the effect of tunneling on the detection time ...

Optical antennas driven by quantum tunneling: a key issues review [PDF]

open access: yesReports on progress in physics. Physical Society, 2019
Analogous to radio- and microwave antennas, optical nanoantennas are devices that receive and emit radiation at optical frequencies. Until recently, the realization of electrically driven optical antennas was an outstanding challenge in nanophotonics. In

Quantum Gravitational Non-Singular Tunneling Wavefunction Proposal

open access: yesPhysical Sciences Forum, 2023
It has recently been shown that the tunneling wavefunction proposal is consistent with loop quantum geometry corrections, including both holonomy and inverse scale factor corrections, in the gravitational part of a spatially closed isotropic model with a

Quantum interference effects in multi-channel correlated tunneling structures

open access: yesScientific 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 ...

Quantum Mechanical Aspects in the Pathophysiology of Neuropathic Pain

open access: yesBrain Sciences, 2022
Neuropathic pain is a challenging complaint for patients and clinicians since there are no effective agents available to get satisfactory outcomes even though the pharmacological agents target reasonable pathophysiological mechanisms.

Decoherence on Quantum Tunneling in the Multi-Dimensional Wave Function Approach [PDF]

open access: yes, 1994
We consider fundamental problems on the understanding of the tunneling phenomena in the context of the multi-dimensional wave function. In this paper, we reconsider the quantum state after tunneling and extend our previous formalism to the case when the ...

Quantum Tunneling on Graphs [PDF]

open access: yesCommunications in Mathematical Physics, 2012
We explore the tunneling behavior of a quantum particle on a finite graph, in the presence of an asymptotically large potential. Surprisingly the behavior is governed by the local symmetry of the graph around the wells.

Light from van der Waals quantum tunneling devices [PDF]

open access: yesNature Communications, 2018
The understanding of and control over light emission from quantum tunneling has challenged researchers for more than four decades due to the intricate interplay of electrical and optical properties in atomic scale volumes.

Quantum mechanical aspects of cardiac arrhythmias: A mathematical model and pathophysiological implications

open access: yesAIMS Biophysics, 2023
Cardiac arrhythmias are serious myocardial electrical disturbances that affect the rate and rhythm of heartbeats. Despite the rapidly accumulating data about the pathophysiology and the treatment, new insights are required to improve the overall clinical

Quantum tunneling time [PDF]

open access: yesAmerican Journal of Physics, 2004
A simple model of a quantum clock is applied to the old and controversial problem of how long a particle takes to tunnel through a quantum barrier. The model has the advantage of yielding sensible results for energy eigenstates and does not require the use of time-dependent wave packets.
