Boson Stars with Large Self-interaction in (2+1) dimensions: an Exact Solution
An exact solution for a nonrotating boson star in (2+1) dimensional gravity
with a negative cosmological constant is found. The relations among mass,
particle number, and radius of the (2+1) dimensional boson star are shown.Comment: 16 pages, 7 figures, needs REVTeX (2nd revised version
Deconstructing Scalar QED at Zero and Finite Temperature
We calculate the effective potential for the WLPNGB in a world with a
circular latticized extra dimension. The mass of the WLPNGB is calculated from
the one-loop quantum effect of scalar fields at zero and finite temperature. We
show that a series expansion by the modified Bessel functions is useful to
calculate the one-loop effective potentials.Comment: 12 pages, 2 figures. RevTeX
