Quantum tunneling in low-dimensional semiconductors mediated by virtual photons

open access: yesAIP Advances, 2020
Quantum tunneling, a phenomenon that has no counterpart in classical physics, is the quantum-mechanical process by which a microscopic particle can transition through a potential barrier even when the energy of the incident particle is lower than the ...

Quantum mechanical state of the quantum system, and tunneling effect (a new approach) [PDF]

open access: yesITM Web of Conferences, 2019
A physical model proposed in this paper resolves existing contradictions between wave and corpuscle properties of quantum particles (electrons) in tunneling effect.

QUANTUM TUNNELING [PDF]

open access: yes, 2002
Dedicated to the memory of Professor Michael Marinov, a friend, a colleague and a man of firm principles who believed in his right to live in peace in Israel, the land of his ancestors (Latex, 5 eps figures, uses sprocl style), to be published in the Michael Marinov Memorial Volume, Eds. M. Olshanetsky and A. Vainshtein (World Scientific, 2002)

Macroscopic quantum tunneling escape of Bose-Einstein condensates [PDF]

open access: yes, 2017
Recent experiments on macroscopic quantum tunneling reveal a non-exponential decay of the number of atoms trapped in a quasibound state behind a potential barrier. Through both experiment and theory, we demonstrate this non-exponential decay results from

Quantum tunneling of thermal protons through pristine graphene. [PDF]

open access: yesJournal of Chemical Physics, 2016
Engineering of atomically thin membranes for hydrogen isotope separation is an actual challenge which has a broad range of applications. Recent experiments [M. Lozada-Hidalgo et al., Science 351, 68 (2016)] unambiguously demonstrate an order-of-magnitude

Tunneling in Polymer Quantization and the Quantum Zeno Effect [PDF]

open access: yes, 2014
As an application of the polymer quantization scheme, in this work we investigate the one dimensional quantum mechanical tunneling phenomenon from the perspective of polymer representation of a non-relativistic point particle and derive the transmission ...

Understanding Quantum Tunneling using Diffusion Monte Carlo Simulations [PDF]

open access: yes, 2017
In simple ferromagnetic quantum Ising models characterized by an effective double-well energy landscape the characteristic tunneling time of path-integral Monte Carlo (PIMC) simulations has been shown to scale as the incoherent quantum-tunneling time, i ...

Quantum Tunneling of Ions through the Closed Voltage-Gated Channels of the Biological Membrane: A Mathematical Model and Implications

open access: yesQuantum Reports, 2019
Voltage-gated channels play an essential role in action potential propagation when their closed gates open, but their role when they are closed needs to be investigated. So, in this study, a quantum mechanical approach using the idea of quantum tunneling

Magnetic-field-induced singularities in spin dependent tunneling through InAs quantum dots [PDF]

open access: yes, 2000
Current steps attributed to resonant tunneling through individual InAs quantum dots embedded in a GaAs-AlAs-GaAs tunneling device are investigated experimentally in magnetic fields up to 28 T. The steps evolve into strongly enhanced current peaks in high

Quantum tunneling with friction [PDF]

open access: yes, 2017
Using the phenomenological quantum friction models introduced by Caldirola-Kanai, Kostin, and Albrecht, we study quantum tunneling of a one-dimensional potential in the presence of energy dissipation.
