Standing Waves in a Non-linear 1D Lattice : Floquet Multipliers, Krein Signatures, and Stability
Subhendu Panda, Anindita Lahiri, Tarun K. Roy +1
We construct a class of exact commensurate and incommensurate standing wave (SW) solutions in a piecewise smooth analogue of the discrete non-linear Schrödinger (DNLS) model and pr…

Breathers in a Discrete Nonlinear Schrödinger type Model : Exact Stability Results
Avijit Lahiri, Subhendu Panda, Tarun K. Roy
Exact stability analysis of 1-site breathers in an NLS type model (ref. [4], see below) indicates destabilisation through a growth rate becoming positive as a stability border is c…
