A new quantization principle from a minimally non time-ordered product
Damiano Anselmi
We formulate a new quantization principle for perturbative quantum field theory, based on a minimally non time-ordered product, and show that it gives the theories of physical part…
Modular conjugations in 2D conformal field theory and holographic bit threads
Mihail Mintchev, Erik Tonni
We study the geometric action of some modular conjugations in two dimensional (2D) conformal field theories. We investigate the bipartition given by an interval when the system is…
CFTs with Global Symmetry in 3D and the Chiral Phase Transition of QCD
Stefanos R. Kousvos, Andreas Stergiou
Conformal field theories (CFTs) with global symmetry in dimensions have been studied for years due to their potential relevance to the chiral phase transiti…
Projective transformations in metric-affine and Weylian geometries
Dario Sauro, Riccardo Martini, Omar Zanusso
We discuss generalizations of the notions of projective transformations acting on affine model of Riemann-Cartan and Riemann-Cartan-Weyl gravity which preserve the projective struc…
Purely virtual extension of quantum field theory for gauge invariant fields: quantum gravity
Damiano Anselmi
Quantum gravity is extended to include purely virtual "cloud sectors", which allow us to define a complete set of point-dependent observables, including a gauge invariant metric an…
Spectrum continuity and level repulsion: the Ising CFT from infinitesimal to finite
Johan Henriksson, Stefanos R. Kousvos, Marten Reehorst
Using numerical conformal bootstrap technology we perform a non-perturbative study of the Ising CFT and its spectrum from infinitesimal to finite values of . Explo…
Entanglement entropies of an interval in the free Schrödinger field theory on the half line
Mihail Mintchev, Diego Pontello, Erik Tonni
We study the entanglement entropies of an interval adjacent to the boundary of the half line for the free fermionic spinless Schrödinger field theory at finite density and zero tem…
Near-BPS Skyrmions
Sven Bjarke Gudnason, Marco Barsanti, Stefano Bolognesi
We consider the Skyrme model in the near-BPS limit. The BPS part is made of the sextic term plus a potential and the deformation is made of the standard massive Skyrme model contro…
Dynamical Abelianization and anomalies in chiral gauge theories
Stefano Bolognesi, Kenichi Konishi, Andrea Luzio
We explore the idea that in some class of strongly-coupled chiral gauge theories the infrared dynamics might be characterized by a bifermion condensate in the adjoint repre…
The continuation method and the real analyticity of the accessory parameters: the parabolic case
Pietro Menotti
We give the proof of the real analyticity of the accessory parameters in Liouville field theory as a function of the position of the sources in the case in which in addition to ell…
Causality Constraints on Black Holes beyond GR
Francesco Serra, Javi Serra, Enrico Trincherini +1
We derive causality constraints on the simplest scalar-tensor theories in which black holes differ from what General Relativity predicts, a scalar coupled to the Gauss-Bonnet or th…
Gauge fixing and metric independence in topological quantum theories
Enore Guadagnini, Federico Rottoli, Frank Thuillier
We consider topological gauge theories in three dimensions which are defined by metric independent lagrangians. It has been claimed that the functional integration necessarily depe…
On the time dependence of holographic complexity for charged AdS black holes with scalar hair
Roberto Auzzi, Stefano Bolognesi, Eliezer Rabinovici +2
In the presence of a scalar hair perturbation, the Cauchy horizon of a Reissner-Nordström black hole disappears and is replaced by the rapid collapse of the Einstein-Rosen bridge,…
Narain CFTs and Quantum Codes at Higher Genus
Johan Henriksson, Ashish Kakkar, Brian McPeak
Code CFTs are 2d conformal field theories defined by error-correcting codes. Recently, Dymarsky and Shapere generalized the construction of code CFTs to include quantum error-corre…
Bounding Violations of the Weak Gravity Conjecture
Johan Henriksson, Brian McPeak, Francesco Russo +1
The black hole weak gravity conjecture (WGC) is a set of linear inequalities on the four-derivative corrections to Einstein--Maxwell theory. Remarkably, in four dimensions, these c…
Purely Virtual Particles in Quantum Gravity, Inflationary Cosmology and Collider Physics
Damiano Anselmi
We review the concept of purely virtual particle and its uses in quantum gravity, primordial cosmology and collider physics. The fake particle, or "fakeon", which mediates interact…
The origin of Weyl gauging in metric-affine theories
Dario Sauro, Omar Zanusso
In the first part, we discuss the interplay between local scale invariance and metric-affine degrees of freedom from few distinct points of view. We argue, rather generally, that t…
Purely virtual particles versus Lee-Wick ghosts: physical Pauli-Villars fields, finite QED and quantum gravity
Damiano Anselmi
We reconsider the Lee-Wick (LW) models and compare their properties to the properties of the models that contain purely virtual particles. We argue against the LW premise that unst…
Weyl Covariance and the Energy Momentum Tensors of Higher-Derivative Free Conformal Field Theories
Andreas Stergiou, Gian Paolo Vacca, Omar Zanusso
Energy momentum tensors of higher-derivative free scalar conformal field theories in flat spacetime are discussed. Two algorithms for the computation of energy momentum tensors are…
On the Derivation of Chiral Symmetry Breaking in QCD-like Theories and S-confining Theories
Andrea Luzio, Ling-Xiao Xu
Recent works argue that the pattern of chiral symmetry breaking in QCD-like theories can be derived from supersymmetric (SUSY) QCD with perturbation of anomaly-mediated SUSY breaki…
The critical O(N) CFT: Methods and conformal data
Johan Henriksson
The critical CFT in spacetime dimensions is one of the most important examples of a conformal field theory, with the Ising CFT at , , as a not…
Entanglement entropies of an interval in the free Schrödinger field theory at finite density
Mihail Mintchev, Diego Pontello, Alberto Sartori +1
We study the entanglement entropies of an interval on the infinite line in the free fermionic spinless Schrödinger field theory at finite density and zero temperature, which is a n…
