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…
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…
Non-Pauli Effects from Noncommutative Spacetimes
A. P. Balachandran, Pramod Padmanabhan
Noncommutative spacetimes lead to nonlocal quantum field theories (qft's) where spin-statistics theorems cannot be proved. For this reason, and also backed by detailed arguments, i…
Non-Pauli Transitions From Spacetime Noncommutativity
A. P. Balachandran, Anosh Joseph, Pramod Padmanabhan
There are good reasons to suspect that spacetime at Planck scales is noncommutative. Typically this noncommutativity is controlled by fixed "vectors" or "tensors" with numerical en…
Quantum Fields on Noncommutative Spacetimes: Theory and Phenomenology
Aiyalam P. Balachandran, Alberto Ibort, Giuseppe Marmo +1
In the present work we review the twisted field construction of quantum field theory on noncommutative spacetimes based on twisted Poincaré invariance. We present the latest develo…
