Journal of Mathematical Analysis and Applications, 2007 AbstractWe study the semi-classical trace formula at a critical energy level for a Schrödinger operator on Rn. We assume here that the potential has a totally degenerate critical point associated to a local minimum. The main result, which computes the contribution of this equilibrium, is valid for all time in a compact and establishes the existence of ...

Slow and fast light propagation through ladder-type atomic media with degenerate energy levels
Facta universitatis - series: Physics, Chemistry and Technology, 2019 We investigate the weak probe pulse propagation through the atomic medium, in the presence of the strong control laser field, under the regime of the electromagnetically induced transparency (EIT). These fields couple to the medium by forming the 3-level ladder configuration.

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.

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.

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].
