Influence functionals and black body radiation
J. R. Anglin
The Feynman-Vernon formalism is used to obtain a microscopic, quantum mechanical derivation of black body radiation, for a massless scalar field in 1+1 dimensions, weakly coupled t…
Conformal Invariance and Degrees of Freedom in the QCD String
Keith R. Dienes, Jean-Rene Cudell
We demonstrate that the Hagedorn-like growth of the number of observed meson states can be used to constrain the degrees of freedom of the underlying effective QCD string. We find…
Flows for rectangular matrix models
Rene Lafrance, Robert C. Myers
Several new results on the multicritical behavior of rectangular matrix models are presented. We calculate the free energy in the saddle point approximation, and show that at the t…
Central Charge Reduction and Spacetime Statistics in the Fractional Superstring
Philip C. Argyres, Keith R. Dienes
Fractional superstrings in the tensor-product formulation experience ``internal projections'' which reduce their effective central charges. Simple expressions for the characters of…
Extended Fractional Supersymmetric Quantum Mechanics
Stephane Durand
Recently, we presented a new class of quantum-mechanical Hamiltonians which can be written as the power of a conserved charge: with This constructio…
Canonical Transformations in Quantum Mechanics
Arlen Anderson
Quantum canonical transformations are defined algebraically outside of a Hilbert space context. This generalizes the quantum canonical transformations of Weyl and Dirac to include…
