We compute the effective actions for the 0+1 dimensional scalar field interacting with an Abelian gauge background, as well as for its supersymmetric generalization at finite temperature.

This talk summarizes some theoretical features and experimental implications of a general Lorentz-violating extension of the minimal SU(3) × SU(2)× U(1) standard model that allows for both CPT-even and CPT-odd effects. The theory would arise as the low-energy limit of a fundamental theory that is Lorentz and CPT covariant but in which spontaneous Lorentz breaking occurs. The use of neutral-meso...

v 1 1 3 O ct 1 99 8 The Global Minimum of the Effective Potential of the Many - Electron System with Delta - Interaction

We prove that the global minimum of the real part of the full effective potential of the many electron system with attractive delta interaction is in fact given by the BCS mean field configuration. This is a consequence of a simple bound which is obtained by applying Hadamard’s inequality to the functional determinant. The second order Taylor expansion around the minimum is computed. ∗ e-mail: ...
