Notes on massless scalar field partition functions, modular invariance and Eisenstein series
Francesco Alessio, Glenn Barnich, Martin Bonte
The partition function of a massless scalar field on a Euclidean spacetime manifold and with momentum operator in the compact spatial dimension…
Double Quantization
Giulia Gubitosi, Fedele Lizzi, José Javier Relancio +1
In a quantum gravity theory, it is expected that the classical notion of spacetime disappears, leading to a quantum structure with new properties. A possible way to take into accou…
Bulk area law for boundary entanglement in spin network states: entropy corrections and horizon-like regions from volume correlations
Goffredo Chirco, Eugenia Colafranceschi, Daniele Oriti
For quantum gravity states associated to open spin network graphs, we study how the entanglement entropy of the boundary degrees of freedom (spins on open edges) is affected by the…
More on the Weak Gravity Conjecture via Convexity of Charged Operators
Oleg Antipin, Jahmall Bersini, Francesco Sannino +2
The Weak Gravity Conjecture has recently been re-formulated in terms of a particle with non-negative self-binding energy. Because of the dual conformal field theory (CFT) formulati…
Gravitational effects on neutrino decoherence in Lense-Thirring metric
Giuseppe Gaetano Luciano, Massimo Blasone
We analyze gravity effects on neutrino wave packet decoherence. As a specific example, we consider the gravitational field of a spinning spherical body described by the Lense-Thirr…
From dS to AdS and back
Charlotte Sleight, Massimo Taronna
We describe in more detail the general relation uncovered in our previous work between boundary correlators in de Sitter (dS) and in Euclidean anti-de Sitter (EAdS) space, at any o…
Spontaneous Lorentz symmetry violation from infrared gravity
Fabrizio Illuminati, Gaetano Lambiase, Luciano Petruzziello
In this paper, we investigate a novel implication of the non-negligible spacetime curvature at large distances when its effects are expressed in terms of a suitably modified form o…
More on the cubic versus quartic interaction equivalence in the model
Oleg Antipin, Jahmall Bersini, Francesco Sannino +2
We compute the scaling dimensions of a family of fixed-charge operators at the infrared fixed point of the model featuring cubic interactions in for arbitrary to…
Exact 1/N expansion of Wilson loop correlators in Super-Yang-Mills theory
Wolfgang Mück
Supersymmetric circular Wilson loops in Super-Yang-Mills theory are discussed starting from their Gaussian matrix model representations. Previous results on the gen…
Gribov horizon in Noncommutative QED
Ozório Holanda, Marcelo S. Guimaraes, Luigi Rosa +1
It is known that Noncommutative QED (NCQED) exhibits Gribov ambiguities in the Landau gauge. These ambiguities are related to zero modes of the Faddeev-Popov operator and arise in…
Reparameterization Dependence and Holographic Complexity of Black Holes
Ayoub Mounim, Wolfgang Mück
We refine the calculation of holographic complexity of black holes in the complexity equals action approach by applying the recently introduced criterion that the action of any cau…
On the consistency of (partially-)massless matter couplings in de Sitter space
Charlotte Sleight, Massimo Taronna
We study the consistency of the cubic couplings of a (partially-)massless spinning field to two scalars in -dimensional de Sitter space. Gauge invariance of obser…
A Simple Model of Double Dynamics on Lie Groups
Patrizia Vitale
We study the dynamics of the rigid rotator on the group manifold of SU(2) as an instance of dynamics on Lie groups together with a dual model whose carrier space is the Borel group…
Topological and dynamical aspects of Jacobi sigma models
Francesco Bascone, Franco Pezzella, Patrizia Vitale
The geometric properties of sigma models with target space a Jacobi manifold are investigated. In their basic formulation, these are topological field theories - recently introduce…
Holographic maps from quantum gravity states as tensor networks
Eugenia Colafranceschi, Goffredo Chirco, Daniele Oriti
We define bulk/boundary maps corresponding to quantum gravity states in the tensorial group field theory formalism, for quantum geometric models sharing the same type of quantum st…
q-generalized Tsallis thermostatistics in Unruh effect for mixed fields
Giuseppe Gaetano Luciano, Massimo Blasone
It was shown that the particle distribution detected by a uniformly accelerated observer in the inertial vacuum (Unruh effect) deviates from the pure Planckian spectrum when consid…
Vacuum thermal effects in flat space-time from conformal quantum mechanics
Michele Arzano
The generators of radial conformal symmetries in Minkowski space-time can be mapped to the generators of time evolution in conformal quantum mechanics. Within this correspondence w…
Revisiting Higher-Spin Gyromagnetic Couplings
Raffaele Marotta, Massimo Taronna, Mritunjay Verma
We analyze Bosonic, Heterotic, and Type II string theories compactified on a generic torus having constant moduli. By computing the hamiltonian giving the interaction between massi…
Untangling scaling dimensions of fixed charge operators in Higgs Theories
Oleg Antipin, Jahmall Bersini, Francesco Sannino +2
We go beyond a systematic review of the semiclassical approaches for determining the scaling dimensions of fixed-charge operators in and models by introducing a gener…
-Poincaré-comodules, Braided Tensor Products and Noncommutative Quantum Field Theory
Fedele Lizzi, Flavio Mercati
We discuss the obstruction to the construction of a multiparticle field theory on a -Minkowski noncommutative spacetime: the existence of multilocal functions which respect the…
The free and safe fate of symmetry non-restoration
Borut Bajc, Adrian Lugo, Francesco Sannino
We investigate the high temperature fate of four dimensional gauge-Yukawa theories featuring short distance conformality of either interacting or non-interacting nature. The latter…
Flavor vacuum entanglement in boson mixing
Massimo Blasone, Fabrizio Illuminati, Giuseppe Gaetano Luciano +1
Mixing transformations in quantum field theory are non-trivial, since they are intimately related to the unitary inequivalence between Fock spaces for fields with definite mass and…
Reparameterization Dependence is Useful for Holographic Complexity
Ayoub Mounim, Wolfgang Mück
Holographic complexity in the "complexity equals action" approach is reconsidered relaxing the requirement of reparameterization invariance of the action with the prescription that…
Time Discretization From Noncommutativity
Fedele Lizzi, Patrizia Vitale
We show that a particular noncommutative geometry, sometimes called angular or -Minkowski, requires that the spectrum of time be discrete. In this noncommutative space the time…
