Tunneling Quantum Dynamics in Ammonia [PDF]
International Journal of Molecular Sciences, 2021 Ammonia is a well-known example of a two-state system and must be described in quantum-mechanical terms. In this article, we will explain the tunneling phenomenon that occurs in ammonia molecules from the perspective of trajectory-based quantum dynamics, rather than the usual quantum probability perspective.

Quantum Corrected Non-Thermal Radiation Spectrum from the Tunnelling Mechanism
Galaxies, 2015 The tunnelling mechanism is today considered a popular and widely used method in describing Hawking radiation. However, in relation to black hole (BH) emission, this mechanism is mostly used to obtain the Hawking temperature by comparing the probability ...

Analysis of the decay time and bound-states energies of a particle in a specific structure GaMnAs/GaAs quantum well [PDF]
Computer Methods in Materials ScienceThe bound states and decay time in a certain quantum well structure (GaMnAs/GaAs) were analyzed and identified at the minimum decay time. Through the analysis of quantum mathematical equations, we derived specific formulas for energies that significantly

Large effects from small QCD instantons: making soft bombs at hadron colliders
Journal of High Energy Physics, 2020 It is a common belief that the last missing piece of the Standard Model of particles physics was found with the discovery of the Higgs boson at the Large Hadron Collider.

Quantum tunneling in nuclear fusion [PDF]
Reviews of Modern Physics, 1998 Recent theoretical advances in the study of heavy ion fusion reactions below the Coulomb barrier are reviewed. Particular emphasis is given to new ways of analyzing data, such as studying barrier distributions; new approaches to channel coupling, such as the path integral and Green function formalisms; and alternative methods to describe nuclear ...

Quantum tunneling and stochastic resonance [PDF]
Physical Review E, 1996 Stochastic resonance (SR) occurs in nonlinear dynamical systems when the response to a weak coherent input is enhanced by the presence of noise. While classical SR presently is an intensely studied phenomenon, the role of quantum fluctuations has only started to be explored.

Tunnelling amplitudes through localised external potentials from Feynman diagram summation
European Physical Journal C: Particles and FieldsCurrently there is no general theory of quantum tunnelling of a particle through a potential barrier which is compatible with QFT. We present a complete calculation of tunnelling amplitudes for a scalar field for some simple potentials using quantum ...

An open quantum systems approach to proton tunnelling in DNA
Communications Physics, 2022 The genetic stability of DNA suffers from proton transfer along the hydrogen bonds that can lead to tautomerisation, creating mutations. The authors theoretically examine the tautomerisation of the GuanineCytosine (G-C) nucleotide base-pair using an open
