One-loop analysis with nonlocal boundary conditions

Giampiero Esposito, Elisabetta Di Grezia

In the eighties, Schroder studied a quantum mechanical model where the stationary states of Schrodinger's equation obey nonlocal boundary conditions on a circle in the plane. For s…

Localization and Reference Frames in $κ$ -Minkowski Spacetime

Fedele Lizzi, Mattia Manfredonia, Flavio Mercati +1

We study the limits to the localizability of events and reference frames in the $κ$ -Minkowski quantum spacetime. Our main tool will be a representation of the $κ$ -Minkowski commuta…

Multiloop Soft Theorem for Gravitons and Dilatons in the Bosonic String

Paolo Di Vecchia, Raffaele Marotta, Matin Mojaza

We construct, in the closed bosonic string, the multiloop amplitude involving $N$ tachyons and one massless particle with $26 - D$ compactified directions, and we show that at least…

Antisymmetric Wilson loops in N = 4 SYM: from exact results to non-planar corrections

Anthonny F. Canazas Garay, Alberto Faraggi, Wolfgang Mück

We consider the vacuum expectation values of 1/2-BPS circular Wilson loops in N=4 super Yang-Mills theory in the totally antisymmetric representation of the gauge group U(N) or SU(…

Anomalous Dimensions from Crossing Kernels

Charlotte Sleight, Massimo Taronna

In this note we consider the problem of extracting the corrections to CFT data induced by the exchange of a primary operator and its descendents in the crossed channel. We show how…

Noncommutative field theory from angular twist

Marija Dimitrijevic Ciric, Nikola Konjik, Maxim A. Kurkov +2

We consider a noncommutative field theory with space-time $⋆$ -commutators based on an angular noncommutativity, namely a solvable Lie algebra: the Euclidean in two dimension. T…

Thermal and spectral dimension of (generalized) Snyder noncommutative spacetimes

Giovanni Amelino-Camelia, Flaminia Giacomini, Giulia Gubitosi

We report an investigation of the Snyder noncommutative spacetime and of some of its most natural generalizations, also looking at them as a powerful tool for comparing different n…

Doubling, T-Duality and Generalized Geometry: a Simple Model

Vincenzo Emilio Marotta, Franco Pezzella, Patrizia Vitale

A simple mechanical system, the three-dimensional isotropic rigid rotator, is here investigated as a 0+1 field theory, aiming at further investigating the relation between Generali…

Entangled Scent of a Charge

M. Asorey, A. P. Balachandran, F. Lizzi +1

We argue that the ground state of a field theory, in the presence of charged particles, becomes an entangled state involving an infinity of soft photons. The quantum field vacuum i…

Gravitational parity anomaly with and without boundaries

Maxim Kurkov, Dmitri Vassilevich

In this paper we consider gravitational parity anomaly in three and four dimensions. We start with a re-computation of this anomaly on a 3D manifold without boundaries and with a c…

Clifford Structures in Noncommutative Geometry and the Extended Scalar Sector

Maxim A. Kurkov, Fedele Lizzi

We consider aspects of the noncommutative approach to the standard model based on the spectral action principle. We show that as a consequence of the incorporation of the Clifford…
