The Schrödinger equation for the Rosen-Morse type potential revisited with applications
Guillermo Gordillo-Núñez, Renato Alvarez-Nodarse, Niurka R. Quintero
We rigorously solve the time-independent Schrödinger equation for the Rosen-Morse type potential. By using the Nikiforov-Uvarov method, we obtain, in a systematic way, the complete…
Collective Coordinates Theory for Discrete Soliton Ratchets in the sine-Gordon Model
B. Sánchez-Rey, N. R. Quintero, J. Cuevas-Maraver +1
A collective coordinate theory is develop for soliton ratchets in the damped discrete sine-Gordon model driven by a biharmonic force. An ansatz with two collective coordinates, nam…
Stability of solitary waves in the nonlinear Dirac equation with arbitrary nonlinearity
Sihong Shao, Niurka R. Quintero, Franz G. Mertens +3
We consider the nonlinear Dirac equation in 1+1 dimension with scalar-scalar self interaction and with mass . Using the exact analytic form…
Reply to Comment on "Existence of Internal Modes of sine-Gordon Kinks"
Niurka R. Quintero, Angel Sanchez, Franz G. Mertens
In this reply to the comment by C. R. Willis, we show, by quoting his own statements, that the simulations reported in his original work with Boesch [Phys. Rev. B 42, 2290 (1990)]…
