Low temperature transport and evidence for nuclear order in GaAs Quantum Wires [PDF]
, 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
AIP 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]
Physical 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.

Tailoring Quantum Tunneling in a Vanadium‐Doped WSe2/SnSe2 Heterostructure
Advancement of science, 2019 2D van der Waals layered heterostructures allow for a variety of energy band offsets, which help in developing valuable multifunctional devices. However, p–n diodes, which are typical and versatile, are still limited by the material choice due to the ...

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

Quantum tunneling and trace anomaly [PDF]
Physics 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 ...

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

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