Slave boson model for two-dimensional trapped Bose-Einstein condensate
K. K. Rajagopal
A system of N bosons in a two-dimensional harmonic trap is considered. The system is treated in term of the slave boson representation for hard-core bosons which is valid in the ar…
Feshbach resonance in a strictly two-dimensional atomic Bose gas
K. K. Rajagopal, P. Vignolo, M. P. Tosi
We discuss the atom-atom scattering problem across a Feshbach resonance in a two-dimensional dilute Bose gas at zero temperature, in the limit where the s-wave scattering length ex…
Microscopic Theory of Trapped Two-Dimensional Bose Gas
K. K. Rajagopal
This report is based on my incomplete Phd thesis. The final part of the work on the 2D Yukawa bosons/vortices in a confined geometry is not complete and subject to futher developme…
Yukawa bosons in two-dimensional Harmonic confinement
K. K. Rajagopal
The ground state property of Yukawa Bose fluid confined in a radial harmonic trap is studied. The calculation was carried out using the density functional theory formalism within t…
Temperature dependence of the energy of a vortex in a two-dimensional Bose gas
K. K. Rajagopal, B. Tanatar, P. Vignolo +1
We evaluate the thermodynamic critical angular velocity Omega_c(T) for creation of a vortex of lowest quantized angular momentum in a strictly two-dimensional Bose gas at temperatu…
