Open strings in the system D5/D9

P. Di Vecchia, R. Marotta, I. Pesando +1

We construct the six-dimensional Lagrangian for the massless twisted open strings with one end-point ending on a stack of D5 and the other on a stack of D9 branes, interacting with…

A Study on Charged Neutron Star in

Vincenzo Parente, Raju Roychowdhury

Motivated by an open question raised in recent times regarding the phase transition during the collapse of a neutron star to form a black hole and related stability issues, we have…

Covariant Quantum Fields on Noncommutative Spacetimes

A. P. Balachandran, A. Ibort, G. Marmo +1

A spinless covariant field on Minkowski spacetime $\M^{d+1}$ obeys the relation where is an element of the Poincaré group $\Pg$ and $U:(…

A pedagogical introduction to the Slavnov formulation of quantum Yang-Mills theory

Hossein Ghorbani, Giampiero Esposito

Over the last few years, Slavnov has proposed a formulation of quantum Yang-Mills theory in the Coulomb gauge which preserves simultaneously manifest Lorentz invariance and gauge i…

Quantum Geons and Noncommutative Spacetimes

A. P. Balachandran, A. Ibort, G. Marmo +1

Physical considerations strongly indicate that spacetime at Planck scales is noncommutative. A popular model for such a spacetime is the Moyal plane. The Poincarè group algebra act…

On the transition from complex to real scalar fields in modern cosmology

Giampiero Esposito, Raju Roychowdhury, Claudio Rubano +1

We study some problems arising from the introduction of a complex scalar field in cosmology, modelling its possible behaviors in both the inflationary and dark energy stages of the…

About the Non Relativistic Structure of the AdS/CFT Superalgebras

Antonino Sciarrino, Paul Sorba

The property of the conformal algebra to contain the Schrödinger algebra in one less space dimension is extended to the supersymmetric case. More precisely, we determine the counte…

The Cardy-Verlinde equation in a spherical symmetric gravitational collapse

Giuseppe Maiella, Cosimo Stornaiolo

The Cardy-Verlinde formula is analyzed in the contest of the gravitational collapse. Starting from the holographic principle, we show how the equations for a homogeneous and isotro…

Noncommutative spaces with twisted symmetries and second quantization

Gaetano Fiore

In a minimalistic view, the use of noncommutative coordinates can be seen just as a way to better express non-local interactions of a special kind: 1-particle solutions (wavefuncti…

Running Scaling Dimensions in Holographic Renormalization Group Flows

Wolfgang Mueck

Holographic renormalization group flows can be interpreted in terms of effective field theory. Based on such an interpretation, a formula for the running scaling dimensions of gaug…

Repulsive Casimir Force: Sufficient Conditions

Luigi Rosa, Astrid Lambrecht

In this paper the Casimir energy of two parallel plates made by materials of different penetration depth and no medium in between is derived. We study the Casimir force density and…

Dark energy from modified gravity with Lagrange multipliers

Salvatore Capozziello, Jiro Matsumoto, Shin'ichi Nojiri +1

We study scalar-tensor theory, k-essence and modified gravity with Lagrange multiplier constraint which role is to reduce the number of degrees of freedom. Dark Energy cosmology of…

Paired quantum Hall states on noncommutative two-tori

Vincenzo Marotta, Adele Naddeo

By exploiting the notion of Morita equivalence for field theories on noncommutative tori and choosing rational values of the noncommutativity parameter theta (in appropriate units)…

Gauge Symmetry Breaking in Matrix Models

Harald Grosse, Fedele Lizzi, Harold Steinacker

We argue that some features of the standard model, in particular the fermion assignment and symmetry breaking, can be obtained in matrix model which describes noncommutative gauge…

Noncommutative gauge theory and symmetry breaking in matrix models

Harald Grosse, Fedele Lizzi, Harold Steinacker

We show how the fields and particles of the standard model can be naturally realized in noncommutative gauge theory. Starting with a Yang-Mills matrix model in more than 4 dimensio…

Bosonic Spectral Action Induced from Anomaly Cancelation

A. A. Andrianov, Fedele Lizzi

We show how (a slight modification of) the noncommutative geometry bosonic spectral action can be obtained by the cancelation of the scale anomaly of the fermionic action. In this…
