ANTONOV WETTING LINE PHASE TRANSITION OF TWO-COMPONENT BOSE-EINSTEIN CONDENSATES UNDER CONSTRAINT OF ROBIN BOUNDARY CONDITION

Tạp chí Khoa học Đại học Đà Lạt, 2018
Using double Parabola approximation, in this paper, after finding the wave function for the ground state, we found an analytical relation for wetting phase transition and Antonov line of two-component Bose-Einstein condensates.

On the p-Laplacian with Robin boundary conditions and boundary trace theorems [PDF]

Calculus of Variations and Partial Differential Equations, 2017
Let $ \subset\mathbb{R}^ $, $ \ge 2$, be a $C^{1,1}$ domain whose boundary $\partial $ is either compact or behaves suitably at infinity. For $p\in(1,\infty)$ and $ >0$, define \[ ( ,p, ):=\inf_{\substack{u\in W^{1,p}( )\\ u\not\equiv 0}}\dfrac{\displaystyle \int_ |\nabla u|^p \mathrm{d} x - \displaystyle\int_{\partial } |u|^p\mathrm{d}

Impact of space-time curvature coupling on the vacuum energy induced by a magnetic topological defect in flat space-time of arbitrary dimension

Nuclear Physics B
We have investigated vacuum polarization of a quantized charged massive scalar field in the presence of a magnetic topological defect, modeled as an impenetrable tube of finite thickness carrying magnetic flux. At the tube’s surface, we imposed a general

The Dirichlet-to-Robin Transform

, 2004
A simple transformation converts a solution of a partial differential equation with a Dirichlet boundary condition to a function satisfying a Robin (generalized Neumann) condition.

Modelling Angiogenesis Under Robin Boundary Conditions

Quantitative Biology
AbstractIn this study, we show an example of a numerical model based on the Keller–Segel system of equations to simulate angiogenesis in response to chemotaxis under Robin boundary conditions, which represent the presence of flux at the tumor. Different parameters of the model are modified to identify key biological factors relevant to the behavior of ...

Casimir effect for the scalar field under Robin boundary conditions: A functional integral approach

, 2003
In this work we show how to define the action of a scalar field in a such a way that Robin boundary condition is implemented dynamically, i.e., as a consequence of the stationary action principle. We discuss the quantization of that system via functional

Equivalent Robin boundary conditions for acoustic and elastic media [PDF]

Mathematical Models and Methods in Applied Sciences, 2016
We present equivalent conditions and asymptotic models for a diffraction problem of acoustic and elastic waves. The mathematical problem is set with a Robin boundary condition. Elastic and acoustic waves propagate in a solid medium surrounded by a thin layer of fluid medium. Due to the thinness of the layer with respect to the wavelength, this problem

Highly Accurate Method for Boundary Value Problems with Robin Boundary Conditions

Journal of Nonlinear Mathematical Physics, 2023
AbstractThe main aim of the current paper is to construct a numerical algorithm for the numerical solutions of second-order linear and nonlinear differential equations subject to Robin boundary conditions. A basis function in terms of the shifted Chebyshev polynomials of the first kind that satisfy the homogeneous Robin boundary conditions is ...
