Modulational instability and discrete quantum droplets in a deep quasi-one-dimensional optical lattice
Sherzod R. Otajonov, Bakhram A. Umarov, Fatkhulla Kh. Abdullaev
We study the properties of modulational instability and discrete breathers arising in a quasi-one-dimensional discrete Gross-Pitaevskii equation with Lee-Huang-Yang corrections. Co…
PT-symmetry Management in Oligomer Systems
R. L. Horne, J. Cuevas, P. G. Kevrekidis +3
We study the effects of management of the PT-symmetric part of the potential within the setting of Schrödinger dimer and trimer oligomer systems. This is done by rapidly modulating…
Symmetry breaking, coupling management, and localized modes in dual-core discrete nonlinear-Schrödinger lattices
H. Susanto, P. G. Kevrekidis, F. Kh. Abdullaev +1
We introduce a system of two linearly coupled discrete nonlinear Schrödinger equations (DNLSEs), with the coupling constant subject to a rapid temporal modulation. The model can be…
