Regularizing Property of the Maximal Acceleration Principle in Quantum Field Theory

V. V. Nesterenko, A. Feoli, G. Lambiase +1

It is shown that the introduction of an upper limit to the proper acceleration of a particle can smooth the problem of ultraviolet divergencies in local quantum field theory. For t…

Casimir Energy of a Ball and Cylinder in the Zeta Function Technique

G. Lambiase, V. V. Nesterenko, M. Bordag

A simple method is proposed to construct the spectral zeta functions required for calculating the electromagnetic vacuum energy with boundary conditions given on a sphere or on an…

On Ellipticity and Gauge Invariance in Euclidean Quantum Gravity

Ivan G. Avramidi, Giampiero Esposito

Invariance principles determine many key properties in quantum field theory, including, in particular, the appropriate form of the boundary conditions. A crucial consistency check…

Off-shell amplitudes for nonoriented closed strings

L. Cappiello, R. Marotta, R. Pettorino +1

In the context of the bosonic closed string theory, by using the operatorial formalism, we give a simple expression of the off-shell amplitude with an arbitrary number of external…

Scattering from Singular Potentials in Quantum Mechanics

Giampiero Esposito

In non-relativistic quantum mechanics, singular potentials in problems with spherical symmetry lead to a Schrodinger equation for stationary states with non-Fuchsian singularities…

Probability representation in quantum field theory

V. I. Man'ko, L. Rosa, P. Vitale

The recently proposed probability representation of quantum mechanics is generalized to quantum field theory. We introduce a probability distribution functional for field configura…

String Geometry and the Noncommutative Torus

G. Landi, F. Lizzi, R. J. Szabo

We construct a new gauge theory on a pair of d-dimensional noncommutative tori. The latter comes from an intimate relationship between the noncommutative geometry associated with a…

Current Oscillations, Interacting Hall Discs and Boundary CFTs

A. P. Balachandran, G. Bimonte, T. R. Govindarajan +3

In this paper, we discuss the behavior of conformal field theories interacting at a single point. The edge states of the quantum Hall effect (QHE) system give rise to a particular…

On off-shell bosonic string amplitudes

L. Cappiello, R. Marotta, R. Pettorino +1

We give a simple prescription for computing, in the framework of the bosonic string theory, off-shell one-loop amplitudes with any number of external massless particles, both for t…

Fourth-Order Operators on Manifolds with Boundary

Giampiero Esposito, Alexander Yu. Kamenshchik

Recent work in the literature has studied fourth-order elliptic operators on manifolds with boundary. This paper proves that, in the case of the squared Laplace operator, the bound…
