We study the finite-size and boundary effects on a p-wave superconductor in a
mesoscopic rectangular sample using Ginzburg-Landau (GL) and quasi-classical
(QC) Green's function theory. Except for a square sample with parameters far
away from the isotropic weak-coupling limit, the ground state near the critical
temperature always prefers a time-reversal symmetric state, where the order
parameter can be represented by a real vector. For large aspect ratio, this
vector is parallel to the long side of the rectangle. Within a critical aspect
ratio, it has instead a vortex-like structure, vanishing at the sample center.
We also discuss the enhancement of critical temperature from QC theory within
the weak-coupling limit as compared with GL theory.
