In is shown explicitly that the Witten's interaction 3-vertex is a solution to the comma overlap equations; hence establishing the equivalence between the conventional and the " comma " formulation of interacting string theory at the level of vertices.

We study the Casimir effect with different temperatures between the plates (T) resp. outside of them (T ′). If we consider the inner system as the black body radiation for a special geometry, then contrary to common belief the temperature approaches a constant value for vanishing volume during isentropic processes. This means: the reduction of the degrees of freedom can not be compensated by a ...

We analyze the cutoff dependence of the fermion contribution to the finite temperature free energy density in O(g 2) lattice perturbation theory for several improved staggered fermion actions. Cutoff effects are drastically reduced for the Naik action and an action with improved rotational symmetry of the quark propagator. We show that improvement of rotational symmetry at O(g 2) further reduce...
