Insensitive edge solitons in a non-Hermitian topological lattice
Bertin Many Manda, Vassos Achilleos
In this work, we demonstrate that the synergetic interplay of topology, nonreciprocity and nonlinearity is capable of unprecedented effects. We focus on a nonreciprocal variant of…
Skin modes in a nonlinear Hatano-Nelson model
Bertin Many Manda, Ricardo Carretero-González, Panayotis G. Kevrekidis +1
Non-Hermitian lattices with non-reciprocal couplings under open boundary conditions are known to possess linear modes exponentially localized on one edge of the chain. This phenome…
Nonlinear Topological Edge States: from Dynamic Delocalization to Thermalization
Bertin Many Manda, Rajesh Chaunsali, Georgios Theocharis +1
We consider a mechanical lattice inspired by the Su-Schrieffer-Heeger model along with cubic Klein-Gordon type nonlinearity. We investigate the long-time dynamics of the nonlinear…
Chaotic dynamics of graphene and graphene nanoribbons
Malcolm Hillebrand, Bertin Many Manda, George Kalosakas +2
We study the chaotic dynamics of graphene structures, considering both a periodic, defect free, graphene sheet and graphene nanoribbons (GNRs) of various widths. By numerically cal…
