Solitary waves in the resonant nonlinear Schrödinger equation: stability and dynamical properties
F. Williams, F. Tsitoura, T. P. Horikis +1
The stability and dynamical properties of the so-called resonant nonlinear Schrödinger (RNLS) equation, are considered. The RNLS is a variant of the nonlinear Schrödinger (NLS) equ…
Dark solitons for an extended quintic nonlinear Schrödinger equation: Application to water waves at
F. Tsitoura, T. P. Horikis, D. J. Frantzeskakis
We study the existence, formation and dynamics of gray solitons for an extended quintic nonlinear Schrödinger (NLS) equation. The considered model finds applications to water waves…
Phase domain walls in weakly nonlinear deep water surface gravity waves
F. Tsitoura, U. Gietz, A. Chabchoub +1
We report the theoretical derivation and the experimental as well as numerical observation of nonlinear phase domain walls in weakly nonlinear deep water surface gravity waves. The…
Dark Soliton Scattering in Symmetric and Asymmetric Double Potential Barriers
F. Tsitoura, Z. A. Anastassi, J. L. Marzuola +2
Motivated by the recent theoretical study of (bright) soliton diode effects in systems with multiple scatterers, as well as by experimental investigations of soliton-impurity inter…
Dark solitons near potential and nonlinearity steps
F. Tsitoura, Z. A. Anastassi, J. L. Marzuola +2
We study dark solitons near potential and nonlinearity steps and combinations thereof, forming rectangular barriers. This setting is relevant to the contexts of atomic Bose-Einstei…
Scattering of matter-waves in spatially inhomogeneous environments
F. Tsitoura, P. Krüger, P. G. Kevrekidis +1
We study scattering of quasi one-dimensional matter-waves at an interface of two spatial domains, one with repulsive and one with attractive interatomic interactions. It is shown t…
Dark-bright Solitons and their Lattices in Atomic Bose-Einstein Condensates
D. Yan, F. Tsitoura, P. G. Kevrekidis +1
In the present contribution, we explore a host of different stationary states, namely dark-bright solitons and their lattices, that arise in the context of multi-component atomic B…
Non-autonomous bright-dark solitons and Rabi oscillations in multi-component Bose-Einstein condensates
T. Kanna, R. Babu Mareeswaran, F. Tsitoura +2
We study the dynamics of non-autonomous bright-dark matter-wave solitons in two- and three- component Bose-Einstein condensates. Our setting includes a time-dependent parabolic pot…
Matter-wave solitons in the counterflow of two immiscible superfluids
F. Tsitoura, V. Achilleos, B. A. Malomed +3
We study formation of solitons induced by counterflows of immiscible superfluids. Our setting is based on a quasi-one-dimensional binary Bose-Einstein condensate (BEC), composed of…
