Covariant Quantum Fields on Noncommutative Spacetimes
A. P. Balachandran, A. Ibort, G. Marmo +1
A spinless covariant field on Minkowski spacetime $\M^{d+1}$ obeys the relation where is an element of the Poincaré group $\Pg$ and $U:(…
Quantum Geons and Noncommutative Spacetimes
A. P. Balachandran, A. Ibort, G. Marmo +1
Physical considerations strongly indicate that spacetime at Planck scales is noncommutative. A popular model for such a spacetime is the Moyal plane. The Poincarè group algebra act…
Three Approaches to Classical Thermal Field Theory
E. Gozzi, R. Penco
In this paper we study three different functional approaches to classical thermal field theory, which turn out to be the classical counterparts of three well-known different formul…
Thermal phases of D1-branes on a circle from lattice super Yang-Mills
Simon Catterall, Anosh Joseph, Toby Wiseman
We report on the results of numerical simulations of 1+1 dimensional SU(N) Yang-Mills theory with maximal supersymmetry at finite temperature and compactified on a circle. For larg…
Unusual Thermodynamics on the Fuzzy 2-Sphere
Sanatan Digal, Pramod Padmanabhan
Higher spin Dirac operators on both the continuum sphere() and its fuzzy analog() come paired with anticommuting chirality operators. A consequence of this is seen in t…
Thermofield dynamics and twisted Poincaré symmetry on Moyal space-time
A. P. Balachandran, T. R. Govindarajan
On Moyal space-time, one can implement twisted Poincaré symmetry with the resultant modification of symmetrization and anti-symmetrization postulates for bosons and fermions. We de…
