Theory of Electron Transport in Two-Barrier Five-Layer Semiconductor Structures
East European Journal of PhysicsThe dependence of the transparency coefficient of a five-layer two-barrier structure on the electron energy and the ratio of the widths of two neighboring potential barriers is calculated.

The heteroclinic connection problem for general double-well potentials [PDF]
, 2014 By variational methods, we provide a simple proof of existence of a heteroclinic orbit to a second order Hamiltonian ODE that connects the two global minima of a double-well potential.

On a Kirchhoff type problems with potential well and indefinite potential
Electronic Journal of Differential Equations, 2015 In this paper, we study the following Kirchhoff type problem:% $$ \left\{\aligned&-\bigg(α\int_{\bbr^3}|\nabla u|^2dx+1\bigg)Δu+(λa(x)+a_0)u=|u|^{p-2}u&\text{ in }\bbr^3,\\% &u\in\h,\endaligned\right.\eqno{(\mathcal{P}_{α,λ})}% $$ where ...

Equilibration and nonclassicality of a double-well potential [PDF]
Scientific Reports, 2016 AbstractA double well loaded with bosonic atoms represents an ideal candidate to simulate some of the most interesting aspects in the phenomenology of thermalisation and equilibration. Here we report an exhaustive analysis of the dynamics and steady state properties of such a system locally in contact with different temperature reservoirs. We show that

An infinite square-well potential as a limiting case of a square-well potential in a minimal-length scenario [PDF]
International Journal of Modern Physics A, 2020 One of the most widely problem studied in quantum mechanics is of an infinite square-well potential. In a minimal-length scenario its study requires additional care because the boundary conditions at the walls of the well are not well fixed. In order to avoid this we solve the finite square-well potential whose the boundary conditions are well fixed ...

Particle tunneling and scattering in a three-dimensional potential with a hard core and an external potential barrier [PDF]
Ядерна фізика та енергетика, 2009 The non-relativistic particle tunneling and scattering through a spherical three-dimensional potential barrier (either rectangular, or Coulomb repulsion), containing a spherical potential rectangular well with a hard core inside, had been studied.

Novel light beam propagation through optical "potential well"
, 2003 The propagation of a Gaussian-shaped beam through a slab of optically denser dielectric medium in the air, a two-dimensional optical counterpart of the quantum potential well, is investigated in order to elucidate the negative lateral shifts of ...

Energy distribution of the "shake off" electrons of the atomic shell at internal conversion [PDF]
Ядерна фізика та енергетика, 2009 Researches of the energy spectrum of electrons of "shake off" are conducted at internal conversion of transition 122 keV E2 in the decay of 152Eu. The measurements are executed in the range of 200 - 1000 eV on the installation of coincidences of γ-quanta
