Exact solutions for time-dependent complex symmetric potential well
Acta Polytechnica, 2023 Using the pseudo-invariant operator method, we investigate the model of a particle with a time-dependent mass in a complex time-dependent symmetric potential well V (x, t) = if (t) |x|.

Molecular theory considering nuclear potential wells
Journal of Molecular Modeling, 2021 Abstract This article introduces potential wells around nuclei and their roles in chemical bonds. The approach uses one-electron Bohr atomic model concept. Multi-electron atoms are converted to one-electron atoms by grounding all inactive, non-reacting electrons using the Apparent Nuclear Charge (ANC) and Electron Shielding Effect (ESE ...

Ergodic properties of heterogeneous diffusion processes in a potential well. [PDF]
Journal of Chemical Physics, 2019 Heterogeneous diffusion processes can be well described by an overdamped Langevin equation with space-dependent diffusivity D(x). We investigate the ergodic and nonergodic behavior of these processes in an arbitrary potential well U(x) in terms of the ...

From quartic anharmonic oscillator to double well potential
Acta Polytechnica, 2022 Quantum quartic single-well anharmonic oscillator Vao(x) = x2 + g2x4 and double-well anharmonic oscillator Vdw(x) = x2(1−gx)2 are essentially one-parametric, they depend on a combination (g2ℏ).

Information-theoretic measures for a position-dependent mass system in an infinite potential well [PDF]
Physica A: Statistical Mechanics and its Applications, 2019 In this work we calculate the Cramer–Rao, the Fisher–Shannon and the Lopez–Ruiz–Mancini–Calbert (LMC) complexity measures for eigenstates of a deformed Schrodinger equation, being this intrinsically linked with position-dependent mass (PDM) systems.

Laser and Particle Beams, 1987 Nonmonotonic plasma potential structures are a common feature of many double layers and sheaths. Steady state plasma potential wells separating regions having different plasma potentials are often found in laboratory experiments. In order to exist, such structures all must find a solution to a common problem.

Acousto-optic coupling in 1-D phoxonic potential well nanobeam cavity using slow modes
International Journal of Optomechatronics, 2023 We propose a novel acousto-optic (AO) devise using suspended fishbone nanobeams based on phononic and photonic potential well (PnPW and PtPW). We aim to reduce the traditional device size and eliminate the need for mirror regions in 1-D nanobeam cavity ...

Quantum traversal time across a potential well [PDF]
Physical Review A, 2019 We consider the quantum traversal time of an incident wave packet across a potential well using the theory of quantum time of arrival (TOA)-operators. This is done by constructing the corresponding TOA-operator across a potential well via quantization ...
