Energy Levels in Nanowires and Nanorods with a Finite Potential Well
Advances in Condensed Matter Physics, 2020 The energy of electrons and holes in cylindrical quantum wires with a finite potential well was calculated by two methods. An analytical expression is approximately determined that allows one to calculate the energy of electrons and holes at the first ...

Potential well theory for the derivative nonlinear Schrödinger equation [PDF]
Analysis & PDE, 2020 We consider the following nonlinear Schrodinger equation of derivative type: \begin{equation}i \partial_t u + \partial_x^2 u +i |u|^{2} \partial_x u +b|u|^4u=0 , \quad (t,x) \in \mathbb{R}\times\mathbb{R}, \ b \in\mathbb{R}. \end{equation} If $b=0$, this

Instantonic Approach to Triple-Well Potential [PDF]
Modern Physics Letters A, 1997 By using the usual instanton method, we obtain the energy splitting due to quantum tunneling through the triple-well barrier. It is shown that the term related to the midpoint of the energy splitting in propagator is quite different from that of double-well case, in that it is proportional to the algebraic average of the frequencies of the left and ...

X-point potential well formation in diverted tokamaks with unfavorable magnetic field direction
Nuclear Fusion, 2020 Fluid simulations of the boundary of fusion plasmas predict the formation of an electric potential well in the vicinity of the X-point in detached divertor conditions with Bt in the unfavorable direction for H-mode access. This potential well arises when
