A Trichotomy for Modified Scattering Across the Yukawa-Coulomb Transition
Yonggeun Cho, Jinyeop Lee
We study the long-time asymptotics of the three-dimensional Hartree equation with Yukawa potential \[ V_μ(x)=\frac{e^{-μ|x|}}{|x|}, \qquad 0\leqμ\leq1. \] The Coulomb case correspo…

Quantitative Derivation of the Two-Component Gross--Pitaevskii Equation in the Hard-Core Limit with Uniform-in-Time Convergence Rate
Jacky Chong, Jinyeop Lee, Zhiwei Sun
We derive the time-dependent two-component Gross--Pitaevskii (GP) equation as an effective description of the dynamics of a dilute two-component Bose gas near its ground state, whi…

Exactly solvable Schrödinger operators related to the confluent equation
Jan Dereziński, Jinyeop Lee
Our paper investigates one-dimensional Schrödinger operators defined as closed operators on or that are exactly solvable in terms of confluent…
