Modular Hamiltonians for the massless Dirac field in the presence of a defect
Mihail Mintchev, Erik Tonni
We study the massless Dirac field on the line in the presence of a point-like defect characterised by a unitary scattering matrix, that allows both reflection and transmission. Con…
Modular Hamiltonians for the massless Dirac field in the presence of a boundary
Mihail Mintchev, Erik Tonni
We study the modular Hamiltonians of an interval for the massless Dirac fermion on the half-line. The most general boundary conditions ensuring the global energy conservation lead…
Bootstrapping mixed correlators in Super Yang-Mills
Agnese Bissi, Andrea Manenti, Alessandro Vichi
We perform a numerical bootstrap study of the mixed correlator system containing the half-BPS operators of dimension two and three in Super Yang-Mills. This setup…
High-order corrections to inflationary perturbation spectra in quantum gravity
Damiano Anselmi
We compute the inflationary perturbation spectra and the quantity to the next-to-next-to-leading log order in quantum gravity with purely virtual particles (which means…
On critical models with scalars in
Alessandro Codello, Mahmoud Safari, Gian Paolo Vacca +1
We adopt a combination of analytical and numerical methods to study the renormalization group flow of the most general field theory with quartic interaction in with a…
Quantum field theories of arbitrary-spin massive multiplets and Palatini quantum gravity
Damiano Anselmi
We formulate quantum field theories of massive fields of arbitrary spins. The presence of both physical and fake particles, organized into multiplets, makes it possible to fulfill…
Cosmic inflation as a renormalization-group flow: the running of power spectra in quantum gravity
Damiano Anselmi
We study the running of power spectra in inflationary cosmology as a renormalization-group flow from the de Sitter fixed point. The beta function is provided by the equations of th…
Is negative kinetic energy meta-stable?
Christian Gross, Alessandro Strumia, Daniele Teresi +1
We explore the possibility that theories with negative kinetic energy (ghosts) can be meta-stable up to cosmologically long times. In classical mechanics, ghosts undergo spontaneou…
RG and logarithmic CFT multicritical properties of randomly diluted Ising models
Riccardo Ben Alì Zinati, Omar Zanusso
We discuss how a spin system, which is subject to quenched disorder, might exhibit multicritical behaviors at criticality if the distribution of the impurities is arbitrary. In ord…
Analytic Baby Skyrmions at Finite Density
Marco Barsanti, Stefano Bolognesi, Fabrizio Canfora +1
We introduce a consistent ansatz for the baby Skyrme model in (2+1)-dimensions which is able to reduce the complete set of field equations to just one equation for the profile func…
Near-BPS baby Skyrmions
Sven Bjarke Gudnason, Marco Barsanti, Stefano Bolognesi
We consider the baby-Skyrme model in the regime close to the so-called restricted baby-Skyrme model, which is a BPS model with area-preserving diffeomorphism invariance. The pertur…
Predictions of quantum gravity in inflationary cosmology: effects of the Weyl-squared term
Damiano Anselmi, Eugenio Bianchi, Marco Piva
We derive the predictions of quantum gravity with fakeons on the amplitudes and spectral indices of the scalar and tensor fluctuations in inflationary cosmology. The action is $R+R…
Hairy Black-holes in Shift-symmetric Theories
Paolo Creminelli, Nicolás Loayza, Francesco Serra +2
Scalar hair of black holes in theories with a shift symmetry are constrained by the no-hair theorem of Hui and Nicolis, assuming spherical symmetry, time-independence of the scalar…
Perturbative BF theory
Enore Guadagnini, Federico Rottoli
We consider a superrenomalizable gauge theory of topological type, in which the structure group is equal to the inhomogeneous group ISU(2). The generating functional of the correla…
The quest for purely virtual quanta: fakeons versus Feynman-Wheeler particles
Damiano Anselmi
The search for purely virtual quanta has attracted interest in the past. We consider various proposals and compare them to the concept of fake particle, or "fakeon". In particular,…
