Thermally activated escape rate and dynamics of a particle under a harmonic potential

Autor: Yoseph Abebe, Tibebe Birhanu, Yigermal Bassie

Publikováno v: Journal of Physics Communications, Vol 8, Iss 1, p 015002 (2024)

In this paper, we study the dynamics of particles along a semiconductor layer by imposing a confinement potential assisted by both thermal noise strength D and trap potential ϕ . By applying a nonhomogeneous cold temperature alongside the uniform ba

Efficiency at Maximum Power in a Parallel Connected Two Quantum Dots Heat Engine

Autor: Tibebe Birhanu, Yigermal Bassie, Yoseph Abebe, Mulugeta Bekele

Publikováno v: Journal of Engineering, Vol 2023 (2023)

In this paper, we proposed a model in which a single level of two quantum dots is connected in parallel and embedded between two leads with different temperatures and chemical potentials. The temperature and chemical potential gradient help the elect

Optimized Efficiency at Two Optimum Operations of a Stochastically Driven Quantum Dot Heat Engine

Autor: Yigermal Bassie, Tibebe Birhanu, Yoseph Abebe, Mulugeta Bekele

Publikováno v: Advances in Mathematical Physics, Vol 2022 (2022)

We take a stochastically driven single-level quantum dot embedded between two metallic leads at different temperatures works as a heat engine. We numerically study the optimized efficiency at two optimum operations, which lies between the maximum and

Thermal and Quantum Fluctuation Effects on Non-Spherical Nuclei: The Case of Spin-1 System

Autor: Mohammed Mahmud, Mulugeta Bekele, Yigermal Bassie

Publikováno v: Condensed Matter, Vol 7, Iss 4, p 62 (2022)

In this work, we investigate the collective role of thermal and quantum fluctuations on non-equilibrium thermodynamics of a quantum system, specifically, the quantum-thermodynamic description of spin-1 nuclei based on the concepts of quantum and stat
