Spinors on a curved noncommutative space: coupling to torsion and the Gross-Neveu model

Maja Buric, John Madore, Luka Nenadovic ยท 2015

We analyse the spinor action on a curved noncommutative space, the so-called truncated Heisenberg algebra, and in particular, the nonminimal coupling of spinors to the torsion. We find that dimensionaโ€ฆ

Improved bounds on the sandpile diffusions on Grid graphs

Ayush Choure, Sundar Vishwanathan ยท 2012

The Abelian Sandpile Model is a discrete diffusion process defined on graphs (Dhar [10], Dhar et al. [11]) which serves as the standard model of self-organized criticality. The transience class of a sโ€ฆ
