Twisted CFT and bilayer Quantum Hall systems

G. Cristofano, V. Marotta, A. Naddeo

We identify the impurity interactions of the recently proposed CFT description of a bilayer Quantum Hall system at filling nu =m/(pm+2) in Mod. Phys. Lett. A 15 (2000) 1679. Such a…

Classical gauge instantons from open strings

M. Billo, M. Frau, F. Fucito +3

We study the D3/D(-1) brane system and show how to compute instanton corrections to correlation functions of gauge theories in four dimensions using open string techniques. In part…

Non-symplectic symmetries and bi-Hamiltonian structures of the rational Harmonic Oscillator

José F. Cariñena, Giuseppe Marmo, Manuel F. Rañada

The existence of bi-Hamiltonian structures for the rational Harmonic Oscillator (non-central harmonic oscillator with rational ratio of frequencies) is analyzed by making use of th…

N=1 Matter from Fractional Branes

R. Marotta, F. Nicodemi, R. Pettorino +2

We study a bound state of fractional D3-branes localized inside the world-volume of fractional D7-branes on the orbifold C^3/Z_2 x Z_2. We determine the open string spectrum that l…

Generalized Weyl systems and kappa-Minkowski space

Alessandra Agostini, Fedele Lizzi, Alessandro Zampini

We introduce the notion of generalized Weyl system, and use it to define *-products which generalize the commutation relations of Lie algebras. In particular we study in a comparat…

N=1 Super Yang Mills renormalization schemes for Fractional Branes

Raffaele Marotta, Francesco Sannino

We investigate N=1 super Yang-Mills theory using fractional branes. We first define the beta-function with respect to a supergravity coordinate. To provide the relation between the…

Chiral bag boundary conditions on the ball

Giampiero Esposito, Klaus Kirsten

Local boundary conditions for spinor fields are expressed in terms of a 1-parameter family of boundary operators, and find applications ranging from (supersymmetric) quantum cosmol…

Cosmological perturbations and short distance physics from Noncommutative Geometry

Fedele Lizzi, Gianpiero Mangano, Gennaro Miele +1

We investigate the possible effects on the evolution of perturbations in the inflationary epoch due to short distance physics. We introduce a suitable non local action for the infl…

An improved correspondence formula for AdS/CFT with multi-trace operators

Wolfgang Mueck

An improved correspondence formula is proposed for the calculation of correlation functions of a conformal field theory perturbed by multi-trace operators from the analysis of the…
