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.

Thermally activated charge fluctuations in GaAs double quantum dots [PDF]

open access: yes, 2014
In this thesis, laterally defined GaAs quantum dots and double quantum dots are investigated by means of real-time charge sensing. A quantum dot charge sensor, adjacent to the investigated double dot system, detects single electron tunneling with ...

Effects of neglecting carrier tunneling on electrostatic potential in calculating direct tunneling gate current in deep submicron MOSFETs [PDF]

open access: yes, 2002
We investigate the validity of the assumption of neglecting carrier tunneling effects on self-consistent electrostatic potential in calculating direct tunneling gate current in deep submicron MOSFETs. Comparison between simulated and experimental results

A diode device combining lateral field-effect transport and vertical tunneling in a multi-quantum-well heterostructure [PDF]

open access: yes, 1992
The authors discuss an electronic device with asymmetric contacts to a InGaAs-InP multilayer heterostructure. Current enters via an alloyed ohmic contact into the quantum wells (QWs) and flows laterally along capacitively coupled channels.

Low temperature transport and evidence for nuclear order in GaAs Quantum Wires [PDF]

open access: yes, 2014
In this thesis we focus on low temperature transport through cleaved edge overgrowth (CEO) quantum wires. This thesis is motivated by recent theoretical work on one hand that predicts the formation of a nuclear helimagnet in presence of a Luttinger ...

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 tunneling with global charge [PDF]

open access: yesPhysical Review D, 1994
We investigate quantum tunneling in the theory of a complex scalar field with a global $U(1)$ symmetry when the charge density of the initial configuration does not vanish. We discuss the possible final configurations and set up the Euclidean path integral formalism to find the bubble nucleation and to study the bubble evolution.

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 ...

Coherent spin dynamics and magnetization transport in nanoscale magnetism [PDF]

open access: yes, 2003
In this dissertation, we present a detailed theoretical analysis of the spin dynam- ics in small antiferromagnetic systems in view of macroscopic quantum phenom- ena, possible applications in quantum information processing, and transport of the ...
