PT-Symmetric dimer in a generalized model of coupled nonlinear oscillators
J. Cuevas-Maraver, A. Khare, P. G. Kevrekidis +2
In the present work, we explore the case of a general PT-symmetric dimer in the context of two both linearly and nonlinearly coupled cubic oscillators. To obtain an analytical hand…
Solitary Waves in a Discrete Nonlinear Dirac equation
J. Cuevas-Maraver, P. G. Kevrekidis, A. Saxena
In the present work, we introduce a discrete formulation of the nonlinear Dirac equation in the form of a discretization of the Gross-Neveu model. The motivation for this discrete…
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…
PT-symmetric sine-Gordon breathers
N. Lu, J. Cuevas-Maraver, P. G. Kevrekidis
In this work, we explore a prototypical example of a genuine continuum breather (i.e., not a standing wave) and the conditions under which it can persist in a -symme…
