Scaling theory for the collapse of a trapped Bose gas in a synthetic magnetic field: a critical study at the condensation point
Bikram Keshari Behera, Shyamal Biswas
We have analytically explored both the zero temperature and the finite temperature scaling theory for the collapse of an attractively interacting 3-D harmonically trapped Bose gas…
