Study of quantum turbulence by vortex-antivortex dynamics in dipolar BECs
S. Sabari, Lauro Tomio
We investigate vortex nucleation and dynamics in a dipolar Bose-Einstein condensate stirred by a rotating Gaussian obstacle. Two stirring protocols are compared: continuous stirrin…
Immiscible to miscible quenching instabilities in two-dimensional binary Bose-Einstein condensates
Lauro Tomio, S. Sabari, Arnaldo Gammal +1
Immiscible to miscible quenching transitions (IMQT) in homogeneous Bose-Einstein condensate are investigated, considering rubidium isotopes Rb and Rb confined in a tw…
Stable Quantum Vortices in Lee-Huang-Yang Dipolar Superfluids
S. Sabari, R. Radha, Lauro Tomio +1
The nucleation and dynamics of vortices in the quasi-two-dimensional rotating dipolar Bose-Einstein condensate are explored by taking into account the Lee-Huang-Yang (LHY) correcti…
Stability of dark solitons in a bubble Bose-Einstein condensate
Raphael Wictky Sallatti, Lauro Tomio, Dmitry Pelinovsky +1
The stability of nonlinear waves on curved surfaces is a problem of widespread interest across physics. Here, we establish the stability criteria for dark solitons on a spherical B…
Modulational instability of inter-spin-orbit coupled Bose-Einstein condensates in deep optical lattice
R. Sasireka, S. Sabari, A. Uthayakumar +1
We present a comprehensive study of modulational instability (MI) in a binary Bose-Einstein condensate with spin-orbit coupling, confined to a deep optical lattice. The system is m…
Vortices in Tunable Dipolar Bose-Einstein condensates with Attractive Interactions
S. Sabari, R. Sasireka, R. Radha +2
We investigate the formation of vortices in quasi-two-dimensional dipolar Bose-Einstein Condensates (BECs) through the interplay between two-body contact and long-ranged dipole-dip…
Rayleigh-Taylor, Kelvin-Helmholtz and immiscible to miscible quenching instabilities in binary Bose-Einstein condensates
R. Kishor Kumar, S. Sabari, Arnaldo Gammal +1
We investigate three kinds of instabilities in binary immiscible homogeneous Bose-Einstein condensate, considering rubidium isotopes Rb and Rb confined in two-dimensi…
Breakup dynamics of a neutron-halo projectile on heavy target at deep sub-barrier energies
B. Mukeru, T. Sithole, Lauro Tomio
By studying the total fusion and breakup cross-sections in the interaction of the neutron-halo projectile on the lead target Pb, it is shown that, even for…
Dynamical vortex production and quantum turbulence in perturbed Bose-Einstein condensates
L. Tomio, A. N. da Silva, S. Sabari +1
Dynamical vortex production and quantum turbulence emerging in periodic perturbed quasi-two-dimensional (q2D) Bose-Einstein condensates are reported by considering two distinct tim…
Vortex dynamics and turbulence in dipolar Bose-Einstein condensates
S. Sabari, R. Kishor Kumar, Lauro Tomio
Quantum turbulence indicators in dipolar Bose-Einstein condensed fluids, following emissions of vortex-antivortex pairs generated by a circularly moving detuned laser, are being pr…
Faraday waves on a bubble Bose-Einstein condensed binary mixture
Leonardo Brito, Lauro Tomio, Arnaldo Gammal
By studying the dynamic stability of Bose-Einstein condensed binary mixtures trapped on the surface of an ideal two-dimensional spherical bubble, we show how the Rabi coupling betw…
Bright solitons in Bose-Einstein condensates with field-induced dipole moments
F. Kh. Abdullaev, A. Gammal, B. A. Malomed +1
We introduce an effectively one-dimensional (1D) model of a bosonic gas of particles carrying collinear dipole moments which are induced by an external polarizing field with the st…
