Dark energy induced by neutrino mixing
Antonio Capolupo, Salvatore Capozziello, Giuseppe Vitiello
The energy content of the vacuum condensate induced by the neutrino mixing is interpreted as dynamically evolving dark energy.
Glueballs vs. Gluinoballs: Fluctuation Spectra in Non-AdS/Non-CFT
Marcus Berg, Michael Haack, Wolfgang Muck
Building on earlier results on holographic bulk dynamics in confining gauge theories, we compute the spin-0 and spin-2 spectra of gauge theories dual to the non-singular Maldacena-…
A CFT description of the BTZ black hole: topology versus geometry (or thermodynamics versus statistical mechanics
G. Maiella, C. Stornaiolo
In this paper we review the properties of the black hole entropy in the light of a general conformal field theory treatment. We find that the properties of horizons of the BTZ blac…
Internal Space for the Noncommutative Geometry Standard Model and Strings
Fedele Lizzi
In this paper I discuss connections between the noncommutative geometry approach to the standard model on one side, and the internal space coming from strings on the other. The sta…
The UV behavior of Gravity at Large N
F. Canfora
A first step in the analysis of the renormalizability of gravity at Large N is carried on. Suitable resummations of planar diagrams give rise to a theory in which there is only a f…
Statistics and UV-IR Mixing with Twisted Poincare Invariance
A. P. Balachandran, T. R. Govindarajan, G. Mangano +3
We elaborate on the role of quantum statistics in twisted Poincare invariant theories. It is shown that, in order to have twisted Poincare group as the symmetry of a quantum theory…
From Peierls brackets to a generalized Moyal bracket for type-I gauge theories
Giampiero Esposito, Cosimo Stornaiolo
In the space-of-histories approach to gauge fields and their quantization, the Maxwell, Yang--Mills and gravitational field are well known to share the property of being type-I the…
Gravitational amplitudes in black-hole evaporation: the effect of non-commutative geometry
Elisabetta Di Grezia, Giampiero Esposito, Gennaro Miele
Recent work in the literature has studied the quantum-mechanical decay of a Schwarzschild-like black hole, formed by gravitational collapse, into almost-flat space-time and weak ra…
CFT description of the Fully Frustrated XY model and phase diagram analysis
Gerardo Cristofano, Vincenzo Marotta, Petter Minnhagen +2
Following a suggestion given in Nucl. Phys. B 300 (1988)611,we show how the U(1)*Z_{2} symmetry of the fully frustrated XY (FFXY) model on a square lattice can be accounted for in…
Energy-momentum tensor for a Casimir apparatus in a weak gravitational field
Giuseppe Bimonte, Enrico Calloni, Giampiero Esposito +1
The influence of the gravity acceleration on the regularized energy-momentum tensor of the quantized electromagnetic field between two plane parallel conducting plates is derived.…
Noncommutative spacetime symmetries: Twist versus covariance
J. M. Gracia-Bondia, Fedele Lizzi, F. Ruiz Ruiz +1
We prove that the Moyal product is covariant under linear affine spacetime transformations. From the covariance law, by introducing an -space where the spacetime coordinates…
q-Quaternions and q-deformed su(2) instantons
Gaetano Fiore
We construct (anti)instanton solutions of a would-be q-deformed su(2) Yang-Mills theory on the quantum Euclidean space R_q^4 [the SO_q(4)-covariant noncommutative space] by reinter…
Casimir energy and the superconducting phase transition
Giuseppe Bimonte, Enrico Calloni, Giampiero Esposito +1
We study the influence of Casimir energy on the critical field of a superconducting film, and we show that by this means it might be possible to directly measure, for the first tim…
Dark Energy: the equation of state description versus scalar-tensor or modified gravity
S. Capozziello, S. Nojiri, S. D. Odintsov
Dark energy dynamics of the universe can be achieved by equivalent mathematical descriptions taking into account generalized fluid equations of state in General Relativity, scalar-…
Twisted Conformal Symmetry in Noncommutative Two-Dimensional Quantum Field Theory
Fedele Lizzi, Sachindeo Vaidya, Patrizia Vitale
By twisting the commutation relations between creation and annihilation operators, we show that quantum conformal invariance can be implemented in the 2-d Moyal plane. This is an e…
