An introduction to quantum gravity
Bryce S. DeWitt, Giampiero Esposito
After an overview of the physical motivations for studying quantum gravity, we reprint THE FORMAL STRUCTURE OF QUANTUM GRAVITY, i.e. the 1978 Cargese Lectures by Professor B.S. DeW…
Neutrino mixing, flavor states and dark energy
M. Blasone, A. Capolupo, S. Capozziello +1
We shortly summarize the quantum field theory formalism for the neutrino mixing and report on recent results showing that the vacuum condensate induced by neutrino mixing can be in…
Novel features of the energy momentum tensor of 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.…
Wrapped Magnetized Branes: Two Alternative Descriptions?
P. Di Vecchia, A. Liccardo, R. Marotta +2
We discuss two inequivalent ways for describing magnetized D-branes wrapped N times on a torus T^2. The first one is based on a non-abelian gauge bundle U(N), while the second one…
Instanton effects in N=1 brane models and the Kahler metric of twisted matter
Marco Billo, Paolo Di Vecchia, Marialuisa Frau +3
We consider locally consistent systems of magnetized D9 branes on an orbifolded six-torus which support N=1 gauge theories. In such realizations, the matter multiplets arise from "…
Instantons in N=2 magnetized D-brane worlds
Marco Billo, Marialuisa Frau, Igor Pesando +3
In a toroidal orbifold of type IIB string theory we study instanton effects in N=2 super Yang-Mills theories engineered with systems of wrapped magnetized D9 branes and Euclidean D…
Twisting all the way: from Classical Mechanics to Quantum Fields
Paolo Aschieri, Fedele Lizzi, Patrizia Vitale
We discuss the effects that a noncommutative geometry induced by a Drinfeld twist has on physical theories. We systematically deform all products and symmetries of the theory. We d…
Isoperiodic classical systems and their quantum counterparts
M. Asorey, J. F. Carinena, G. Marmo +1
One-dimensional isoperiodic classical systems have been first analyzed by Abel. Abel's characterization can be extended for singular potentials and potentials which are not defined…
Black holes, parallelizable horizons and half-BPS states for the Einstein-Gauss-Bonnet theory in five dimensions
Fabrizio Canfora, Alex Giacomini, Ricardo Troncoso
Exact vacuum solutions with a nontrivial torsion for the Einstein-Gauss-Bonnet theory in five dimensions are constructed. We consider a class of static metrics whose spacelike sect…
A new antisymmetric bilinear map for type-I gauge theories
Giampiero Esposito, Cosimo Stornaiolo
In the case of gauge theories, which are ruled by an infinite-dimensional invariance group, various choices of antisymmetric bilinear maps on field functionals are indeed available…
Can QFT on Moyal-Weyl spaces look as on commutative ones?
Gaetano Fiore
We sketch a natural affirmative answer to the question based on a joint work [11] with J. Wess. There we argue that a proper enforcement of the "twisted Poincare'" covariance makes…
Dark energy, cosmological constant and neutrino mixing
A. Capolupo, S. Capozziello, G. Vitiello
The today estimated value of dark energy can be achieved by the vacuum condensate induced by neutrino mixing phenomenon. Such a tiny value is recovered for a cut-off of the order o…
The scalar wave equation in a non-commutative spherically symmetric space-time
Elisabetta Di Grezia, Giampiero Esposito, Gennaro Miele
Recent work in the literature has studied a version of non-commutative Schwarzschild black holes where the effects of non-commutativity are described by a mass function depending o…
Stretched Horizon and Entropy of Superstars
Luca D'Errico, Wolfgang Mueck, Roberto Pettorino
Amongst the class of supergravity solutions found by Lin, Lunin and Maldacena, we consider pure and mixed state configurations generated by phase space densities in the dual fermio…
Relativistic mechanics of Casimir apparatuses in a weak gravitational field
Giuseppe Bimonte, Enrico Calloni, Giampiero Esposito +1
This paper derives a set of general relativistic Cardinal Equations for the equilibrium of an extended body in a uniform gravitational field. These equations are essential for a pr…
q-Deformed su(2) instantons by q-quaternions
Gaetano Fiore
Interpreting the coordinates of the quantum Euclidean space R_q^4 [the SO_q(4)-covariant noncommutative space] as the entries of a ``q-quaternion matrix'' we construct (anti)instan…
A Bound Quantum Particle in a Riemann-Cartan space with Topological Defects and Planar Potential
S. A. Ali, C. Cafaro, S. Capozziello +1
Starting from a continuum theory of defects, that is the analogous to three-dimensional Einstein-Cartan-Sciama-Kibble gravity, we consider a charged particle with spin 1/2 propagat…
On "full" twisted Poincare' symmetry and QFT on Moyal-Weyl spaces
Gaetano Fiore, Julius Wess
We explore some general consequences of a proper, full enforcement of the "twisted Poincare'" covariance of Chaichian et al. [14], Wess [50], Koch et al. [34], Oeckl [41] upon many…
