On operator product expansion in the spin-orbit coupled bosonic system
Rajesh Kumar Gupta, Siddhant Tiwari
Ultra-cold bosonic systems can be tuned to exhibit quantum phase transitions. For example, the Rabi-coupled bosonic system exhibits ferromagnetic and paramagnetic phases, whereas t…

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…
