Constructions of Totally Non-Negative Pfaffian
Jen-Hsu Chang
The totally non-negative pfaffian (TNNP) is define for a skew-symmetric matrix such that all the sub-pfaffians are non-negative. It appears in the pfaffian structure of -functio…
Totally Nonnegative Pfaffian for Solitons in BKP Equation
Jen Hsu Chang
The BKP equation is obtained from the reduction of B type in the KP hierarchy under the orthogonal type transformation group for the KP equation. The skew Schur Q functions can be…
Parity-Time Symmetric Solitons in the Complex KP Equation
Jen-Hsu Chang
One constructs the parity-time symmetric solitons in the complex KP Equation using the totally non-negative Grassmannian. We obtain that every element in the totally non-negative o…
Real Line Solitons of the BKP Equation
Jen-Hsu Chang
The solitons solution of BKP equation can be constructed by the Pfaffian structure. Then one investigates the real line solitons structure of BKP equation using the totally non-neg…
Solitons supported by intensity-dependent dispersion
Chun-Yan Lin, Jen-Hsu Chang, Gershon Kurizki +1
Soliton solutions are studied for paraxial wave propagation with intensity-dependent dispersion. Although the corresponding Lagrangian density has a singularity, analytical solutio…
Quantum Harmonic Oscillators with Nonlinear Effective Masses
Jen-Hsu Chang, Chun-Yan Lin, Ray-Kuang Lee
We study the eigen-energy and eigen-function of a quantum particle acquiring the probability density-dependent effective mass (DDEM) in harmonic oscillators. Instead of discrete ei…
