Uncertainty Principle and Geometric Condition for the Observability of Schrödinger Equations
Longben Wei, Zhiwen Duan, Hui Xu
We provide necessary and sufficient geometric conditions for the exact observability of the Schrödinger equation with inverse-square potentials on the half-line. These conditions a…

Generation of higher-order rogue waves from multi-breathers by double degeneracy in an optical fibre
Lihong Wang, Jingsong He, Hui Xu +1
In this paper, we construct a special kind of breather solution of the nonlinear Schrödinger (NLS) equation, the so-called breather-positon ({\it b-positon} for short), which can b…
