We investigate a gauged matrix model in the large-{ital N} limit that is closely related to the superconductor fluctuation and the flux-lattice melting in two dimensions. With the use of the saddle-point method, the free energy is expanded up to eighth order for the coupling constant {ital g}. In the case that the coefficient of the quadratic term of the Ginzburg-Landau matrix model is negative, a critical point {ital g}={ital g}{sub {ital c}} is obtained in the large-{ital N} limit and the…

The flux-line lattice in superconductors
Magnetic flux can penetrate a type-II superconductor in the form of Abrikosov vortices (also called flux lines, flux tubes, or fluxons) each carrying a quantum of magnetic flux phi 0=h/2e. These tiny
