Curing the UV/IR mixing for field theories with translation-invariant products
Adrian Tanasa, Patrizia Vitale
The ultraviolet/infrared (UV/IR) mixing of noncommutative field theories has been recently shown to be a generic feature of translation- invariant associative products. In this pap…
A review about Invariance Induced Gravity: Gravity and Spin from Local Conformal-Affine Symmetry
S. Capozziello, M. De Laurentis
In this review paper, we discuss how gravity and spin can be obtained as the realization of the local Conformal-Affine group of symmetry transformations. In particular, we show how…
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…
Attractor Flows in st^2 Black Holes
Raju Roychowdhury
Following the same treatment of Bellucci et.al., we obtain the hitherto unknown general solutions of the radial attractor flow equations for extremal black holes, both for non-BPS…
A solution to the anisotropy problem in bouncing cosmologies
V. Bozza, M. Bruni
Bouncing cosmologies are often proposed as alternatives to standard inflation for the explanation of the homogeneity and flatness of the universe. In such scenarios, the present co…
Translation Invariance, Commutation Relations and Ultraviolet/Infrared Mixing
Salvatore Galluccio, Fedele Lizzi, Patrizia Vitale
We show that the Ultraviolet/Infrared mixing of noncommutative field theories with the Gronewold-Moyal product, whereby some (but not all) ultraviolet divergences become infrared,…
On the complete analytic structure of the massive gravitino propagator in four-dimensional de Sitter space
Giampiero Esposito, Raju Roychowdhury
With the help of the general theory of the Heun equation, this paper completes previous work by the authors and other groups on the explicit representation of the massive gravitino…
Non-commutative Kerr black hole
Elisabetta Di Grezia, Giampiero Esposito
This paper applies the first-order Seiberg-Witten map to evaluate the first-order non-commutative Kerr tetrad. The classical tetrad is taken to follow the locally non-rotating fram…
Classifying and avoiding singularities in the alternative gravity dark energy models
S. Capozziello, M. De Laurentis, S. Nojiri +1
The future finite-time singularities emerging in alternative gravity dark energy models are classified and studied in Jordan and Einstein frames. It is shown that such singularity…
Commutation relations for the electromagnetic field in the presence of dielectrics and conductors
Giuseppe Bimonte
We determine the commutation relations satisfied by the quantized electromagnetic field in the presence of macroscopic dielectrics and conductors, with arbitrary dispersive and dis…
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…
Spinor two-point functions and Peierls bracket in de Sitter space
Giampiero Esposito, Raju Roychowdhury
This paper studies spinor two-point functions for spin-1/2 and spin-3/2 fields in maximally symmetric spaces such as de Sitter spacetime, by using intrinsic geometric objects. The…
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…
Kaehler Metrics: String vs Field Theoretical Approach
P. Di Vecchia, A. Liccardo, R. Marotta +1
We use both a string and a field theoretical approach in order to determine respectively the Kaehler metrics of untwisted and twisted open strings attached to magnetized D9 branes…
Twisted Conformal Field Theories and Morita equivalence
Vincenzo Marotta, Adele Naddeo
The Morita equivalence for field theories on noncommutative two-tori is analysed in detail for rational values of the noncommutativity parameter theta (in appropriate units): an is…
