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…
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…
Stability Window of Trapless Polariton Bose-Einstein condensates
S. Sabari, R. Kishor Kumar, R. Radha +1
We theoretically explore the possibility of stabilizing the trapless polariton Bose-Einstein condensates (pBECs). Exploiting the variational method, we solve the associated nonline…
Vortex generation in stirred binary Bose-Einstein condensates
Anacé N. da Silva, R. Kishor Kumar, Ashton S. Bradley +1
The dynamical vortex production, with a trap-confining time-dependent stirred potential, is studied by using mass-imbalanced cold-atom coupled Bose-Einstein condensates (BEC). The…
Spectral analysis for compressible quantum fluids
Ashton S. Bradley, R. Kishor Kumar, Sukla Pal +1
Turbulent fluid dynamics typically involves excitations on many different length scales. Classical incompressible fluids can be cleanly represented in Fourier space enabling spectr…
