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…
Some Thermal Properties of Ideal Gas
Rajesh Kumar Gupta, Meenu
In this article, we investigate the thermal properties of non-relativistic many-body systems at finite temperature and chemical potential. We compute the one-point function of vari…
Non-relativistic Conformal Field Theory in Momentum Space
Rajesh Kumar Gupta, Meenu
Non-relativistic conformal field theory describes many-body physics at unitarity. The correlation functions of the system are fixed by the requirement of conformal invariance. In t…
