The quartic anharmonic oscillator - an oscillator-basis expansion approach. I. Energy levels study and calculation [PDF]
Ядерна фізика та енергетикаFor the quantum quartic anharmonic oscillator with the Hamiltonian H=0.5(p2+x2)+λx4 which is one of the classic traditional quantum-mechanical and quantum-field-theory models, its main physical characteristics and properties are thoroughly studied and ...

Quantized Excitation Spectrum of the Classical Harmonic Oscillator in Zero-Point Radiation [PDF]
, 2012 We report that upon excitation by a single pulse, the classical harmonic oscillator immersed in classical electromagnetic zero-point radiation, as described by random electrodynamics, exhibits a quantized excitation spectrum in agreement to that of the ...

Chemistry – An Asian Journal, EarlyView.Carbon‐rich compounds dehydrobiphenyleno[12]annulenes (DBP[12]As) comprising antiaromatic four‐membered rings (4MR) and 12‐membered ring (12MR) were synthesized and characterized. DBP[12]As feature high HOMO energy levels and narrow HOMO‐LUMO gaps. The 4MRs have stronger antiaromatic character than the 12MR in DBP[12]As. Abstract In this work we report

Quantum decoherence of the damped harmonic oscillator [PDF]
Optics and Spectroscopy, 2007 In the framework of the Lindblad theory for open quantum systems, we determine the degree of quantum decoherence of a harmonic oscillator interacting with a thermal bath. It is found that the system manifests a quantum decoherence which is more and more significant in time.

Astronomische Nachrichten, EarlyView.ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Unveiling the Damped Quantum Harmonic Oscillator
Jurnal Kumparan FisikaThis article dis cusses the often-overlooked "damped" quantum harmonic oscillator, a vibrating system that loses energy over time. We bridge the classical-quantum divide, starting with the familiar equation of motion for a damped oscillator using Hooke's

Effect of electric and magnetic field on thermal property of two dimensional harmonic oscillator
Results in Physics, 2023 The energy spectrum of a 2D quantum harmonic oscillator confined by a hard wall circular cavity of size r0 in the presence of static electric and the magnetic field is computed numerically using the Bessel function basis set and the linear variational ...

Berichte zur Wissenschaftsgeschichte, EarlyView.Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...
