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.

Separation and Quantum Tunneling of Photo-generated Carriers Using a Tribo-Induced Field

open access: yesMatter, 2019
Summary Tribo-induced potential at a metal-insulator-semiconductor sliding junction results in very high interfacial electric field E (∼107–108 V/m). Such fields are used to separate photo-generated electron-hole pairs that transport through the junction

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

The combined viscous semi-classical limit for a quantum hydrodynamic system with barrier potential [PDF]

open access: yes, 2014
We investigate the viscous model of quantum hydrodynamics, which describes the charge transport in a certain semiconductor. Quantum mechanical effects lead to third order derivatives, turning the stationary system into an elliptic system of mixed order ...

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)

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 ...

Investigation of carbon nanotube quantum dots connected to ferromagnetic leads [PDF]

open access: yes, 2015
The implementation of ferromagnetic contacts in complex nanoelectronic devices, e.g. in spin-valves bears great potential for applications and fundamental investigations. Spin-valves are structures with two magnetic contacts and a non-magnetic medium (

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

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.

Nonlinear Electrical Properties of One-Dimensional Nanostructures [PDF]

open access: yes, 2009
A general method is first reported for reliably fabricating highly-ordered conventional superconductor nanowire arrays, with good control over nanowire cross section (down to 10 nm by 11 nm) and length (up to 200 microns).
