Continuous-wave solutions and modulational instability in spinor condensates of positronium
Ishfaq Ahmad Bhat, Thudiyangal Mithun, B. A. Malomed +1
We obtain general continuous-wave (CW)\ solutions in the model of a spinor positronium condensate in the absence of magnetic field. The CW solutions with both in-phase () and…
Study of implosion in an attractive Bose-Einstein condensate
S. Sabari, A. Choudhuri, K. Porsezian +1
By solving the Gross-Pitaevskii equation analytically and numerically, we reexamine the implosion phenomena that occur beyond the critical value of the number of atoms of an attrac…
Dynamical stabilization of two-dimensional trapless Bose-Einstein condensates by three-body interaction and quantum fluctuations
S. Sabari, K. Porsezian, P. Muruganandam
Analyzing a Gross-Pitaevskii equation with cubic, quartic, and quintic nonlinearities through analytical and numerical methods, we examine the stability of two-dimensional (2D) tra…
Ultrashort dark solitons interactions and nonlinear tunneling in the modified nonlinear Schrödinger equation with variable coefficients
N. M. Musammil, K. Porsezian, K. Nithyanandan +2
We present the study of the dark soliton dynamics in an inhomogenous fiber by means of a variable coefficient modified nonlinear Schrödinger equation (Vc-MNLSE) with distributed di…
Modulation instability in quasi two-dimensional spin-orbit coupled Bose-Einstein condensates
S. Bhuvaneswari, K. Nithyanandan, P. Muruganandam +1
We theoretically investigate the dynamics of modulation instability (MI) in two-dimensional spin-orbit coupled Bose-Einstein condensates (BECs). The analysis is performed for equal…
Manipulation of light in a generalized coupled Nonlinear Schrodinger equation
R. Radha, P. S. Vinayagam, K. Porsezian
We investigate a generalized coupled nonlinear Schrodinger (GCNLS) equation containing Self-Phase Modulation (SPM), Cross-Phase Modulation (XPM) and Four Wave Mixing (FWM) describi…
