Anomalies and Tadpoles in Open/Closed String Duality
A. Liccardo, R. Marotta, F. Pezzella
We discuss the role played by the divergences appearing in the interaction between a fractional D3 brane dressed with an SU(N) gauge field and a stack of N fractional D3 branes on…
On the photon Green functions in curved space-time
Giuseppe Bimonte, Enrico Calloni, Luciano Di Fiore +3
Quantization of electrodynamics in curved space-time in the Lorenz gauge and with arbitrary gauge parameter makes it necessary to study Green functions of non-minimal operators wit…
New Results on Holographic Three-Point Functions
Massimo Bianchi, Wolfgang Mück, Maurizio Prisco
We exploit a gauge invariant approach for the analysis of the equations governing the dynamics of active scalar fluctuations coupled to the fluctuations of the metric along hologra…
From the fuzzy disc to edge currents in Chern-Simons Theory
F. Lizzi, P. Vitale, A. Zampini
We present a brief review of the fuzzy disc, the finite algebra approximating functions on a disc, which we have introduced earlier. We also present a comparison with recent papers…
A New Matrix Model for Noncommutative Field Theory
Giovanni Landi, Fedele Lizzi, Richard J. Szabo
We describe a new regularization of quantum field theory on the noncommutative torus by means of one-dimensional matrix models. The construction is based on the Elliott-Evans induc…
Classical brackets for dissipative systems
Giuseppe Bimonte, Giampiero Esposito, Giuseppe Marmo +1
We show how to write a set of brackets for the Langevin equation, describing the dissipative motion of a classical particle, subject to external random forces. The method does not…
Hopf-algebra description of noncommutative-spacetime symmetries
Alessandra Agostini
I give a brief summary of the results reported in hep-th 0306013 in collaboration with G. Amelino-Camelia and F. D'Andrea. I focus on the analysis of the symmetries of -Minkowsk…
Peierls Brackets: from Field Theory to Dissipative Systems
Giuseppe Bimonte, Giampiero Esposito, Giuseppe Marmo +1
A review is given of the Peierls bracket formalism in field theory, and of a new, recent application of this concept to the analysis of dissipative systems.
The Fuzzy Disc
F. Lizzi, P. Vitale, A. Zampini
We introduce a finite dimensional matrix model approximation to the algebra of functions on a disc based on noncommutative geometry. The algebra is a subalgebra of the one characte…
A twisted conformal field theory description of dissipative quantum mechanics
G. Cristofano, V. Marotta, A. Naddeo
We show how the recently proposed CFT for a bilayer Quantum Hall system at filling nu=m/pm+2, the Twisted Model (TM), is equivalent to the system of two massless scalar bosons with…
Hopf-algebra description of noncommutative-spacetime symmetries
Alessandra Agostini, Giovanni Amelino-Camelia, Francesco D'Andrea
In the study of certain noncommutative versions of Minkowski spacetime there is still a large ambiguity concerning the characterization of their symmetries. Adopting as our case st…
Gauge/Gravity Correspondence from Open/Closed String Duality
P. Di Vecchia, A. Liccardo, R. Marotta +1
We compute the annulus diagram corresponding to the interaction of a fractional D3 brane with a gauge field on its world-volume and a stack of N fractional D3 branes on the orbifol…
N=1 Super QCD and Fractional Branes
Franco Pezzella
We show how to get the one-loop beta function and the chiral anomaly of N=1 Super QCD from a stack of fractional N D3-branes localized inside the world-volume of 2M fractional D7-b…
Minimal coupling of the Kalb-Ramond field to a scalar field
E. Di Grezia, S. Esposito
We study the direct interaction of an antisymmetric Kalb-Ramond field with a scalar particle derived from a gauge principle. The method outlined in this paper to define a covariant…
New classical brackets for dissipative systems
G. Bimonte, G. Esposito, G. Marmo +1
A set of brackets for classical dissipative systems, subject to external random forces, are derived. The method is inspired to the old procedure found by Peierls, for deriving the…
A Class of Renormalization Group Invariant Scalar Field Cosmologies
A. Bonanno, G. Esposito, C. Rubano
We present a class of scalar field cosmologies with a dynamically evolving Newton parameter and cosmological term . In particular, we discuss a class of solutions which are…
Perturbative and non-perturbative aspects of pure N=1 super Yang-Mills theory from wrapped branes
Wolfgang Mück
The Maldacena-Nunez solution is generalized to include a number of integration constants, one of which controls the resolution of the singularity of the wrapped D5-brane background…
Peierls Brackets in Field Theory
Giuseppe Bimonte, Giampiero Esposito, Giuseppe Marmo +1
Peierls brackets are part of the space-time approach to quantum field theory, and provide a Poisson bracket which, being defined for pairs of observables which are group invariant,…
