Shifted one-parameter supersymmetric family of quartic asymmetric double-well potentials
H. C. Rosu, S. C. Mancas, P. Chen
Extending our previous work (Rosu, Mancas, Chen, Ann.Phys. 343 (2014) 87-102), we define supersymmetric partner potentials through a particular Riccati solution of the form F(x)=(x…
One-parameter families of supersymmetric isospectral potentials from Riccati solutions in function composition form
Haret C Rosu, Stefan C Mancas, Pisin Chen
In the context of supersymmetric quantum mechanics, we define a potential through a particular Riccati solution of the composition form, F(f(x)), and obtain a generalized Mielnik c…
Scaling analyses based on wavelet transforms for the Talbot effect
H. C. Rosu, J. S. Murguia, A. Ludu
The fractal properties of the transverse Talbot images are analysed with two well-known scaling methods, the wavelet transform modulus maxima (WTMM) and the wavelet transform multi…
Integrable equations with Ermakov-Pinney nonlinearities and Chiellini damping
Stefan C. Mancas, Haret C. Rosu
We introduce a special type of dissipative Ermakov-Pinney equations of the form v_{ζζ}+g(v)v_ζ+h(v)=0, where h(v)=h_0(v)+cv^{-3} and the nonlinear dissipation g(v) is based on the…
