Metastability, collective excitations, and traveling states of one-dimensional spin-orbit-coupled quantum droplets
Harsimranjit Kaur, Ritu, Rajat +2
We study the static and traveling droplet phases of spin-orbit coupled, one-dimensional Bose-Bose mixtures with a Lee-Huang-Yang correction. For the static droplets, employing a va…
Condensation temperature and magnetic phases of trapped coherently coupled Bose gases
Sunilkumar V, Rajat, Sandeep Gautam +1
We investigate condensation and finite-temperature magnetic phase transitions in a coherently (Rabi) coupled Bose gas confined in a three-dimensional harmonic trap. For the noninte…
Metastability, chaos and spectrum tomography for Bose-Hubbard rings and chains
Rajat, Doron Cohen
We analyze the metastability of Bose-Hubbard condensates for finite-size one-dimensional ring lattices and open chains, using a semiclassical tomographic perspective that emphasize…
Spin and density excitations of one-dimensional self-bound Bose-Bose droplets
Ritu, Rajat, Manpreet Singh +2
We study spin and density excitations of one-dimensional self-bound Bose-Bose droplets within Bogoliubov theory, and show that spin excitations come alive, especially as the inters…
Thermal amplification and melting of phases in spin-orbit-coupled spin-1 Bose-Einstein condensates
Ritu, Rajat, Arko Roy +1
We implement Hartree-Fock-Bogoliubov theory with Popov approximation for a homogeneous Raman-induced spin-orbit-coupled spin-1 Bose-Einstein condensate and investigate the effects…
Excitations of a supersolid annular stripe phase in a spin-orbital-angular-momentum-coupled spin-1 Bose-Einstein condensate
Paramjeet Banger, Rajat, Sandeep Gautam
We present a theoretical study of the collective excitations of the supersolid annular stripe phase of a spin-orbital-angular-momentum-coupled (SOAM-coupled) spin-1 Bose-Einstein c…
Collective excitations and universal coarsening dynamics of a spin-orbit-coupled spin-1 Bose-Einstein condensate
Rajat, Paramjeet Banger, Sandeep Gautam
We study the collective excitation spectrum of a Raman-induced spin-orbit-coupled spin-1 Bose-Einstein condensate confined in a quasi-one-dimensional harmonic trap while varying ei…
Temperature-induced supersolidity in spin-orbit-coupled Bose gases
Rajat, Ritu, Arko Roy +1
Close to the superfluid plane-wave (PW) - supersolid stripe (ST) phase transition point of a zero temperature quasi-one-dimensional spin-orbit-coupled Bose gas, we find that an inc…
Quantum phases and spectrum of collective modes in a spin-1 BEC with spin-orbital-angular-momentum coupling
Paramjeet Banger, Rajat, Arko Roy +1
Motivated by the recent experiments [Chen et al., Phys. Rev. Lett 121, 113204 (2018), Chen et al., Phys. Rev. Lett. 121, 250401 (2018)], we investigate the low-lying excitation spe…
Collective excitations in cigar-shaped spin-orbit coupled spin-1 Bose-Einstein condensates
Rajat, Arko Roy, Sandeep Gautam
We theoretically study the collective excitations of a spin-orbit-coupled spin-1 Bose-Einstein condensate with antiferromagnetic spin-exchange interactions in a cigar-shaped trappi…
