Description of energy levels and decay properties in 158Gd nucleus [PDF]
Ядерна фізика та енергетика, 2023 In this paper, IBM-1 and IBM-2 with a SU(3) limit are used to describe the 158Gd isotope. The calculations of energy levels in the ground state, beta-, and gamma-bands are made up, which account for 15 energy levels.

The generalized relativistic harmonic oscillator with a point interaction
Heliyon, 2021 We study the perturbation of the one-dimensional generalized relativistic harmonic oscillator (GRHO) by a Lorentz scalar delta-shaped interaction. By exactly solving the implied Dirac equation, we show that the presence of the singular potential brings ...

Heat rectification through single and coupled quantum dots
New Journal of Physics, 2022 We study heat rectification through quantum dots in the Coulomb blockade regime using a master equation approach. We consider both cases of two-terminal and four-terminal devices. In the two-terminal configuration, we analyze the case of a single quantum

Physical Review Research, 2022 An analytic closed form solution is derived for the bound states of a two-dimensional electron gas subject to a static, inhomogeneous (1/r in plane decaying) magnetic field, including the Zeeman interaction.

Toward relaxation asymmetry: Heating is faster than cooling
Physical Review Research, 2021 An asymmetry in thermal relaxation toward equilibrium has been uncovered for Langevin systems near stable minima [Phys. Rev. Lett. 125, 110602 (2020)10.1103/PhysRevLett.125.110602].

Heliyon, 2023 In this paper, the bound state solutions of the radial Schrödinger equation are obtained in closed form under an improved Scarf II potential energy function (ISPEF) constrained by external magnetic and Aharonov-Bohm (AB) flux fields.

FROM BLOCH MODEL TO THE RATE EQUATIONS II: THE CASE OF ALMOST DEGENERATE ENERGY LEVELS [PDF]
Mathematical Models and Methods in Applied Sciences, 2004 Bloch equations give a quantum description of the coupling between atoms and a driving electric force. It is commonly used in optics to describe the interaction of a laser beam with a sample of atoms. In this paper, we address the asymptotics of these equations for a high frequency electric field, in a weak coupling regime.

Spin–spin relaxation of nuclear quadrupole resonance coherences and the important role of degenerate energy levels [PDF]
Molecular Physics, 2020 We present an extension of a Redfield approach for calculating spin–spin relaxation rates of zero-field nuclear quadrupole resonance (NQR) coherences, which was published in [Kruk et al., PCCP, 201...

Vacuum-field-induced state mixing
SciPost Physics, 2023 By engineering the electromagnetic vacuum field, the induced Casimir-Polder shift (also known as Lamb shift) and spontaneous emission rates of individual atomic levels can be controlled. When the strength of these effects becomes comparable to the energy
