Ballistic annihilation kinetics for a multi-velocity one-dimensional ideal gas

Michel Droz, Pierre-Antoine Rey, Laurent Frachebourg +1

Ballistic annihilation kinetics for a multi-velocity one-dimensional ideal gas is studied in the framework of an exact analytic approach. For an initial symmetric three-velocity di…

Bispectral KP Solutions and Linearization of Calogero-Moser Particle Systems

Alex Kasman

A new construction using finite dimensional dual grassmannians is developed to study rational and soliton solutions of the KP hierarchy. In the rational case, properties of the tau…

Ballistic Annihilation Kinetics: The Case of Discrete Velocity Distributions

P. L. Krapivsky, S. Redner, F. Leyvraz

The kinetics of the annihilation process, $A + A \to 0$ , with ballistic particle motion is investigated when the distribution of particle velocities is {\it discrete}. This discretene…

Dynamical-parameter algorithm for U(1) gauge theory

W. Kerler, C. Rebbi, A. Weber

We present an algorithm for Monte Carlo simulations which is able to overcome the suppression of transitions between the phases in compact U(1) lattice gauge theory in 4 dimensions…

Topological structures and phases in U(1) gauge theory

W. Kerler, C. Rebbi, A. Weber

We show that topological properties of minimal Dirac sheets as well as of currents lines characterize the phases unambiguously. We obtain the minimal sheets reliably by a suitable…

Scaling Behavior of Driven Interfaces Above the Depinning Transition

Hernan A. Makse, Luis A. Nunes Amaral

We study the depinning transition for models representative of each of the two universality classes of interface roughening with quenched disorder. For one of the universality clas…

Simulations of Supercollider Physics

K. D. Lane, F. E. Paige, T. Skwarnicki +1

The Standard Model of particle physics makes it possible to simulate complete events for physics signatures and their backgrounds in high energy collisions. Knowledge of how the pr…

Avalanches and the Directed Percolation Depinning Model: Experiments, Simulations and Theory

L. A. N. Amaral, A. -L. Barabasi, S. V. Buldyrev +4

We study the recently-introduced directed percolation depinning (DPD) model for interface roughening with quenched disorder for which the interface becomes pinned by a directed per…

Limits on the Ununified Standard Model

R. S. Chivukula, E. H. Simmons, J. Terning

The ununified standard model is an extension of the standard model that contains separate electroweak gauge groups for quarks and leptons. When it was originally proposed, data all…

Renormalization of Lattice Gas Transport Coefficients

Bruce M. Boghosian, Washington Taylor

A method is described for calculating corrections to the Boltzmann/Chapman-Enskog analysis of lattice gases due to the buildup of correlations. It is shown that renormalized transp…

Dynamic Scaling of Ion-Sputtered Surfaces

Rodolfo Cuerno, Albert-Laszlo Barabasi

We derive a stochastic nonlinear equation to describe the evolution and scaling properties of surfaces eroded by ion bombardment. The coefficients appearing in the equation can be…

b \rightarrow s γAND Z \rightarrow b \overline{b} IN TECHNICOLOR WITH SCALARS

Christopher D. Carone, Elizabeth H. Simmons, Yumian Su

We consider the radiative decay $b \to s γ$ , and the correction to the $Z b b$ vertex in technicolor models with scalars. In these models, the scalar develops a vac…

Renormalization Group Approach to the Coulomb Pseudopotential for C_{60}

Nikos Berdenis, Ganpathy Murthy

A numerical renormalization group technique recently developed by one of us is used to analyse the Coulomb pseudopotential ( $μ^{*}$ ) in $C_{60}$ for a variety of bare poten…

Dynamics of Surface Roughening with Quenched Disorder

S. Havlin, L. A. N. Amaral, S. V. Buldyrev +2

We study the dynamical exponent $z$ for the directed percolation depinning (DPD) class of models for surface roughening in the presence of quenched disorder. We argue that $z$ for…
