Towards Holographic Renormalization of Fake Supergravity
Natalia Borodatchenkova, Michael Haack, Wolfgang Mueck
A step is made towards generalizing the method of holographic renormalization to backgrounds which are not asymptotically AdS, corresponding to a dual gauge theory which has logari…
Spectral Functions in Holographic Renormalization Group Flows
Wolfgang Mueck
The spectrum of two-point functions in a holographic renormalization group flow from an ultraviolet (UV) to an infrared (IR) conformal fixed point is necessarily continuous. For a…
A general CFT model for antiferromagnetic spin-1/2 ladders with Mobius boundary conditions
Gerardo Cristofano, Vincenzo Marotta, Adele Naddeo +1
We show how the low-energy properties of the 2-leg XXZ spin-1/2 ladders with general anisotropy parameter on closed geometries can be accounted for in the framework of the m-re…
Energy-momentum tensor for a scalar Casimir apparatus in a weak gravitational field: Neumann conditions
George M. Napolitano, Giampiero Esposito, Luigi Rosa
We consider a Casimir apparatus consisting of two perfectly conducting parallel plates, subject to the weak gravitational field of the Earth. The aim of this paper is the calculati…
On second quantization on noncommutative spaces with twisted symmetries
Gaetano Fiore
By application of the general twist-induced star-deformation procedure we translate second quantization of a system of bosons/fermions on a symmetric spacetime in a non-commutative…
The m-reduction in Conformal Field Theory as the Morita equivalence on two-tori
Vincenzo Marotta, Adele Naddeo
We study the Morita equivalence for field theories on noncommutative two-tori. For rational values of the noncommutativity parameter (in appropriate units) we show the equivale…
Topologically protected qubits as minimal Josephson junction arrays with non trivial boundary conditions: a proposal
Gerardo Cristofano, Vincenzo Marotta, Adele Naddeo +1
Recently a one-dimensional closed ladder of Josephson junctions has been studied (G. Cristofano et al., Phys. Lett. A 372 (2008) 2464) within a twisted conformal field theory (CFT)…
Twisted Noncommutative Field Theory with the Wick-Voros and Moyal Products
Salvatore Galluccio, Fedele Lizzi, Patrizia Vitale
We present a comparison of the noncommutative field theories built using two different star products: Moyal and Wick-Voros (or normally ordered). For the latter we discuss both the…
Kaehler Metrics and Yukawa Couplings in Magnetized Brane Models
P. Di Vecchia, A. Liccardo, R. Marotta +1
Using the field theoretical approach introduced by Cremades, Ibanez and Marchesano for describing open strings attached to D9 branes having different magnetizations, we give a proc…
On the consequences of twisted Poincare' symmetry upon QFT on Moyal noncommutative spaces
Gaetano Fiore
We explore some general consequences of a consistent formulation of relativistic quantum field theory (QFT) on the Groenewold-Moyal-Weyl noncommutative versions of Minkowski space…
Accelerating cosmologies from non-local higher-derivative gravity
Salvatore Capozziello, Emilio Elizalde, Shin'ichi Nojiri +1
We study accelerating cosmological solutions of a general class of non-linear gravities which depend on Gauss-Bonnet and other higher derivative invariants. To achieve this goal a…
Dark energy and particle mixing
A. Capolupo, S. Capozziello, G. Vitiello
We show that the vacuum condensate due to particle mixing is responsible of a dynamically evolving dark energy. In particular, we show that values of the adiabatic index close to -…
gravity constrained by PPN parameters and stochastic background of gravitational waves
S. Capozziello, M. De Laurentis, S. Nojiri +1
We analyze seven different viable -gravities towards the Solar System tests and stochastic gravitational waves background. The aim is to achieve experimental bounds for the t…
Noncommutative Conformal Field Theory in the Twist-deformed context
Fedele Lizzi, Patrizia Vitale
We discuss conformal symmetry on the two dimensional noncommutative plane equipped with Moyal product in the twist deformed context. We show that the consistent use of the twist pr…
Noncommutative field theory with the Wick-Voros product
Salvatore Galluccio, Fedele Lizzi, Patrizia Vitale
We study the noncommutative scalar field theory in the presence of the Wick-Voros product (or normally ordered product), a variant of the more studied Moyal product. We discuss bot…
Very Special Relativity in Curved Space-Times
Wolfgang Mueck
The generalization of Cohen and Glashow's Very Special Relativity to curved space-times is considered. Gauging the SIM(2) symmetry does not, in general, provide the coupling to the…
Nonlocal field theory driven by a deformed product. Generalization of Kalb-Ramond duality
Elisabetta Di Grezia, Giampiero Esposito, Gennaro Miele
A modification of the standard product used in local field theory by means of an associative deformed product is proposed. We present a class of deformed products, one for every sp…
The Eastwood-Singer gauge in Einstein spaces
Giampiero Esposito, Raju Roychowdhury
Electrodynamics in curved spacetime can be studied in the Eastwood--Singer gauge, which has the advantage of respecting the invariance under conformal rescalings of the Maxwell equ…
From Rindler space to the electromagnetic energy-momentum tensor of a Casimir apparatus in a weak gravitational field
Giuseppe Bimonte, Giampiero Esposito, Luigi Rosa
This paper studies two perfectly conducting parallel plates in the weak gravitational field on the surface of the Earth. Since the appropriate line element, to first order in the c…
Energy-momentum tensor of a Casimir apparatus in a weak gravitational field: scalar case
Giampiero Esposito, George M. Napolitano, Luigi Rosa
Recent work in the literature had evaluated the energy-momentum tensor of a Casimir apparatus in a weak gravitational field, for an electromagnetic field subject to perfect conduct…
