Effective potential for the reaction-diffusion-decay system
David Hochberg, Carmen Molina-Paris, Juan Perez-Mercader +1
In previous work [cond-mat/9904207,cond-mat/9904215] we have developed a general method for casting stochastic partial differential equations (SPDEs) into a functional integral for…
Effective potential for classical field theories subject to stochastic noise
David Hochberg, Carmen Molina-Paris, Juan Perez-Mercader +1
Classical field theories coupled to stochastic noise provide an extremely powerful tool for modeling phenomena as diverse as turbulence, pattern-formation, and the structural devel…
Dynamical Scaling of Matter Density Correlations in the Universe: an Application of the Dynamical Renormalization Group
A. Dominguez, D. Hochberg, J. M. Martin-Garcia +2
We show how the interplay of non-linear dynamics, self-gravity, and fluctuations leads to self-affine behavior of matter density correlations quite generically, i.e., with a power-…
Ising Model formulation of Large Scale Dynamics: Universality in the Universe
J. Perez--Mercader, T. Goldman, D. Hochberg +1
The partition function of a system of galaxies in gravitational interaction can be cast in an Ising Model form, and this reformulated via a Hubbard--Stratonovich transformation int…
Gamma Ray Bursts, Neutron Star Quakes, and the Casimir Effect
C. Carlson, T. Goldman, J. Perez-Mercader
We propose that the dynamic Casimir effect is a mechanism that converts the energy of neutron starquakes into --rays. This mechanism efficiently produces photons from electromag…
Quark Flavors as Entropy Ordered States of QCD
J. Perez-Mercader
We discuss a natural notion of entropy in quantum field theory and apply it to asymptotically free theories in their perturbative regimes. We then specialize to QCD and find that q…
