Noncommutative Geometry and a Discretized Version of Kaluza-Klein Theory with a Finite Field Content
Nguyen Ai Viet, Kameshwar C. Wali
We consider a four-dimensional space-time supplemented by two discrete points assigned to a algebraic structure and develop the formalism of noncommutative geometry. By setti…
Theory of Double-Sided Flux Decorations
M. Cristina Marchetti, David R. Nelson
A novel two-sided Bitter decoration technique was recently employed by Yao et al. to study the structure of the magnetic vortex array in high-temperature superconductors. Here we d…
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…
Edge states in Gravity and Black Hole Physics
A. P. Balachandran, L. Chandar, Arshad Momen
We show in the context of Einstein gravity that the removal of a spatial region leads to the appearance of an infinite set of observables and their associated edge states localized…
The Forgotten Potts Models
Gudmar Thorleifsson
The q=10 and q=200 state Potts models coupled to 2d gravity are investigated numerically and shown to have continuous phase transitions, contrary to their behavior on a regular lat…
Classical analysis of Bianchi types I and II in Ashtekar variables
Gabriela Gonzalez, Ranjeet S Tate
We solve the complex Einstein equations for Bianchi I and II models formulated in the Ashtekar variables. We then solve the reality conditions to obtain a parametrization of the sp…
