Inequivalence of QFT's on Noncommutative Spacetimes: Moyal versus Wick-Voros
A. P. Balachandran, A. Ibort, G. Marmo +1
In this paper, we further develop the analysis started in an earlier paper on the inequivalence of certain quantum field theories on noncommutative spacetimes constructed using twi…
The Groenewold - Moyal Plane and its Quantum Physics
A. P. Balachandran, Pramod Padmanabhan
Quantum theories constructed on the noncommutative spacetime called the Groenewold-Moyal(GM) plane exhibit many interesting properties such as causality violation, Lorentz and CPT…
Finite Temperature Field Theory on the Moyal Plane
E. Akofor, A. P. Balachandran
In this paper, we initiate the study of finite temperature quantum field theories (QFT's) on the Moyal plane. Such theories violate causality which influences the properties of the…
Causality and statistics on the Groenewold-Moyal plane
A. P. Balachandran, Anosh Joseph, Pramod Padmanabhan
Quantum theories constructed on the noncommutative spacetime called the Groenewold-Moyal plane exhibit many interesting properties such as Lorentz and CPT noninvariance, causality…
Poincare' Quasi-Hopf Symmetry and Non-Associative Spacetime Algebra from Twisted Gauge Theories
A. P. Balachandran, B. A. Qureshi
In previous work, starting from the Moyal plane, we formulated interacting theories of matter and gauge fields with only the former fields twisted. In this approach, gauge theories…
Space-time from Symmetry: The Moyal Plane from the Poincare-Hopf Algebra
A. P. Balachandran, M. Martone
We show how to get a non-commutative product for functions on space-time starting from the deformation of the coproduct of the Poincare' group using the Drinfel'd twist. Thus it is…
Twisted Quantum Fields on Moyal and Wick-Voros Planes are Inequivalent
A. P. Balachandran, M. Martone
The Moyal and Wick-Voros planes A^{M,V}_θ are *-isomorphic. On each of these planes the Poincaré group acts as a Hopf algebra symmetry if its coproducts are deformed by twist facto…
Spontaneous Symmetry Breaking in Twisted Noncommutative Quantum Theories
A. P. Balachandran, T. R. Govindarajan, S. Vaidya
We analyse aspects of symmetry breaking for Moyal spacetimes within a quantisation scheme which preserves the twisted Poincaré symmetry. Towards this purpose, we develop the LSZ ap…
