Fuzzy Nambu-Goldstone Physics
A. P. Balachandran, G. Immirzi
In spacetime dimensions larger than 2, whenever a global symmetry G is spontaneously broken to a subgroup H, and G and H are Lie groups, there are Nambu-Goldstone modes described b…
Chiral spinors and gauge fields in noncommutative curved space-time
Nguyen Ai Viet, Kameshwar C. Wali
The fundamental concepts of Riemannian geometry, such as differential forms, vielbein, metric, connection, torsion and curvature, are generalized in the context of non-commutative…
Tall tales from de Sitter space II: Field theory dualities
Frederic Leblond, Donald Marolf, Robert C. Myers
We consider the evolution of massive scalar fields in (asymptotically) de Sitter spacetimes of arbitrary dimension. Through the proposed dS/CFT correspondence, our analysis points…
On the Singularity Structure and Stability of Plane Waves
Donald Marolf, Leopoldo A. Pando Zayas
We describe various aspects of plane wave backgrounds. In particular, we make explicit a simple criterion for singularity by establishing a relation between Brinkmann metric entrie…
Dirac Operators on Coset Spaces
A. P. Balachandran, Giorgio Immirzi, Joohan Lee +1
The Dirac operator for a manifold Q, and its chirality operator when Q is even dimensional, have a central role in noncommutative geometry. We systematically develop the theory of…
Plane Waves: To infinity and beyond!
Donald Marolf, Simon F. Ross
We describe the asymptotic boundary of the general homogeneous plane wave spacetime, using a construction of the `points at infinity' from the causal structure of the spacetime as…
