Radial dam breaks in a two-dimensional droplet bearing environment
F. Bristy, S. Chandramouli, G. A. Bougas +3
The controlled dynamical generation of radial dam break flows (DBFs) is demonstrated in two-dimensional droplet environments. These ultracold mixtures feature competing mean-field…
Pure-Quartic Optical Shock Waves
Sanjida Yeasmin, Sathyanarayanan Chandramouli, Ziad H. Musslimani +1
In this paper, we study the emergence and dynamics of pure-quartic optical dispersive shock waves governed by the nonlinear Schrödinger (NLS) equation with self-defocusing Kerr non…
Homoclinic and heteroclinic solutions of the nonlinear Schrödinger equation with a complex Wadati potential
Sathyanarayanan Chandramouli, Patrick Sprenger, Mark A. Hoefer
Stationary solutions asymptoting to nonlinear plane waves of the nonlinear Schrödinger equation with a PT-symmetric, complex linear potential are characterized. The potential inclu…
Dispersive shock waves in periodic lattices
Su Yang, Sathyanarayanan Chandramouli, Panayotis G. Kevrekidis
We introduce and systematically investigate the generation of dispersive shock waves, which arise naturally in physical settings such as optical waveguide arrays and superfluids co…
Rogue waves in extended Gross-Pitaevskii Models with a Lee-Huang-Yang correction
Sathyanarayanan Chandramouli, Simeon I. Mistakidis, Garyfallia C. Katsimiga +3
We explore the existence and dynamical generation of rogue waves (RWs) within a one dimensional quantum droplet bearing environment. RWs are computed by deploying a spacetime fixed…
Dam breaks in the discrete nonlinear Schrödinger equation
Shrohan Mohapatra, Panayotis G. Kevrekidis, Su Yang +1
In the present work we study the nucleation of Dispersive shock waves (DSW) in the {defocusing}, discrete nonlinear Schr{ö}dinger equation (DNLS), a model of wide relevance to nonl…
Dispersive shock waves in a one-dimensional droplet-bearing environment
Sathyanarayanan Chandramouli, Simeon I. Mistakidis, Garyfallia C. Katsimiga +1
We demonstrate the controllable generation of distinct types of dispersive shock-waves emerging in a quantum droplet bearing environment with the aid of step-like initial condition…
Bright traveling breathers in media with long-range, nonconvex dispersion
Sathyanarayanan Chandramouli, Yifeng Mao, Mark Hoefer
The existence and properties of envelope solitary waves on a periodic, traveling wave background, called traveling breathers, are investigated numerically in representative nonloca…
On the temporal tweezing of cavity solitons
J. Rossi, Sathyanarayanan Chandramouli, R. Carretero-González +1
Motivated by the work of J.K.~Jang et al., Nat.~Commun.~{\bf 6}, 7370 (2015), where the authors experimentally tweeze cavity solitons in a passive loop of optical fiber, we study t…
Observation of Traveling Breathers and Their Scattering in a Two-Fluid System
Yifeng Mao, Sathyanarayanan Chandramouli, Wenqian Xu +1
The observation of traveling breathers (TBs) with large-amplitude oscillatory tails realizes an almost 50-year-old theoretical prediction (Kuznetsov 1975) and generalizes the notio…
Time-Dependent Duhamel Renormalization method with Multiple Conservation and Dissipation Laws
Sathyanarayanan Chandramouli, Aseel Farhat, Ziad Musslimani
The time dependent spectral renormalization (TDSR) method was introduced by Cole and Musslimani as a novel way to numerically solve initial boundary value problems. An important an…
