Thermodynamic limit and -convergence rate for the cubic-quintic Schrödinger model
Deke Li, Yuan Li, Qingxuan Wang
We investigate the thermodynamic limit for the cubic-quintic Schrödinger model as the size of the domain tends to infinity with fixed density , where deno…

The Ground State of a Cubic-quintic Nonlinear Schrödinger Equation with Radial Potential in the Thomas-Fermi Limit
Deke Li, Qingxuan Wang
We focus on the ground state of the cubic-quintic nonlinear Schrödinger energy functional \begin{gather*} \begin{aligned} {E}(Ï)=\frac{1}{2}\int_{\mathbb{R}^d}\left(|\nabla Ï|^2…

Optimal convergence rate to the nonrelativistic limit of Chandrasekhar variational model for Neutron stars
Yuanhui Chen, Qingxuan Wang
In this paper, we consider the nonrelativistic limit of Chandrasekhar variational model for neutron stars. We show that the minimizer of Chandrasekhar energy conv…
