Research interests

My research interest is in the field of applied mathematics and non linear differential equations. I study the existence and stability of fundamental solitons in a parity time (PT)-symmetric coupler and charge parity time (CP) composed by a chain of dimers that is modelled by linearly coupled discrete nonlinear Schrodinger equations with gain and loss terms.
