    The quantum optics of gravitational waves

    by Luca Abrahão, Francesco Coradeschi, Antonia Micol Frassino, Thiago Guerreiro, Jennifer Rittenhouse West, Enrico Junior Schioppa

    By utilizing quantum optics techniques, we examine the characteristics of a quantum gravitational wave (GW) signature at interferometers. In particular, we study the problem by analyzing the equations of motion of a GW interacting with an idealized interferometer. Using this method, we reconstruct the classical GW signal from a representation of the quantum version of an almost classical monochromatic wave (a single-mode coherent state), then we discuss the experimental signatures of some specific, more general quantum states. We calculate the observables that could be used at future interferometers to probe possible quantum states carried by the GWs.

    Review of: "Consistent Interpretation of Quantum and Classical Mechanics"

    by Francesco Coradeschi

    Interpretation of Quantum Mechanics is a fully legitimate field of research; I personally understand the Author's (apparent) frustration with the ‘orthodox interpretation' (for lack of a better word), a phrase which is usually taken to mean some vari...

    Quantum signatures in nonlinear gravitational waves

    by Thiago Guerreiro, Francesco Coradeschi, Antonia Micol Frassino, Jennifer Rittenhouse West, Enrico Junior Schioppa

    The effective quantum field theory description of gravity, despite its non-renormalizability, allows for predictions beyond classical general relativity. As we enter the age of gravitational wave astronomy, an important and timely question is whether measurable quantum predictions that depart from classical gravity, analogous to quantum optics effects which cannot be explained by classical electrodynamics, can be found. In this work, we investigate quantum signatures in gravitational waves using tools from quantum optics. Squeezed-coherent gravitational waves, which can exhibit sub-Poissonian graviton statistics, can enhance or suppress the signal measured by an interferometer, a characteristic effect of quantum squeezing. Moreover, we show that Gaussian gravitational wave quantum states can be reconstructed from measurements over an ensemble of optical fields interacting with a single copy of the gravitational wave, thus opening the possibility of detecting quantum features of gravity beyond classical general relativity.

    Can We Detect the Quantum Nature of Weak Gravitational Fields?

    by Francesco Coradeschi, Antonia Micol Frassino, Thiago Guerreiro, Jennifer Rittenhouse West, Enrico Junior Schioppa

    A theoretical framework for the quantization of gravity has been an elusive Holy Grail since the birth of quantum theory and general relativity. While generations of scientists have attempted to find solutions to this deep riddle, an alternative path built upon the idea that experimental evidence could determine whether gravity is quantized has been decades in the making. The possibility of an experimental answer to the question of the quantization of gravity is of renewed interest in the era of gravitational wave detectors. We review and investigate an important subset of phenomenological quantum gravity, detecting quantum signatures of weak gravitational fields in table-top experiments and interferometers.

    Transverse-momentum resummation for the signal-background interference in the H→γγ channel at the LHC

    by L. Cieri, F. Coradeschi, D. de Florian, N. Fidanza

    We present an upgraded calculation of the effects of resonance-continuum interference for the Higgs boson decaying to two photons at the Large Hadron Collider, at next-to-leading order in the strong coupling αS, O(αS3), and including transverse-momentum (qT) resummation at next-to-leading logarithmic accuracy. We study the importance of the interference contribution in different transverse-momentum regions, with a particular focus on the low-qT region qT2≪Q2 (with Q2 being the invariant diphoton mass) where resummation becomes essential for a reliable calculation.

    Unified limiting form of graviton radiation at extreme energies

    by Marcello Ciafaloni, Dimitri Colferai, Francesco Coradeschi, Gabriele Veneziano

    We derive the limiting form of graviton radiation in gravitational scattering at trans-Planckian energies (E≫MP) and small deflection angles. We show that—owing to the graviton’s spin 2—such a limiting form unifies the soft and Regge regimes of emission, by covering a broad angular range, from forward fragmentation to the deeply central region. The single-exchange emission amplitudes have a nice expression in terms of the transformation phases of helicity amplitudes under rotations. As a result, the multiple-exchange emission amplitudes can be resummed via an impact parameter b-space factorization theorem that takes into account all coherence effects. We then see the emergence of an energy spectrum of the emitted radiation which, being tuned on ℏ/R∼MP2/E≪MP, is reminiscent of Hawking’s radiation. Such a spectrum is much softer than the one naïvely expected for increasing input energies and neatly solves a potential energy crisis. Furthermore, by including rescattering corrections in the (quantum) factorization formula, we are able to recover the classical limit and find the corresponding quantum corrections. Perspectives for the extrapolation of such limiting radiation towards the classical collapse regime (where b is of the order of the gravitational radius R) are also discussed.

    Interference effects in theH(→γγ)+2 jetschannel at the LHC

    by F. Coradeschi, D. de Florian, L. J. Dixon, N. Fidanza, S. Höche, H. Ita, Y. Li, J. Mazzitelli

    We compute the interference between the resonant process pp→H(→γγ)+2 jets and the corresponding continuum background at leading order in QCD. For the Higgs signal, we include gluon fusion (GF) and vector boson fusion (VBF) production channels, while for the background we consider all tree-level contributions, including pure EW effects (O(αQED4)) and QCD contributions (O(αQED2αs2)), plus the loop-induced gluon-initiated process. After convolution with the experimental mass resolution, the main effect of the interference is to shift the position of the mass peak, as in the inclusive GF case studied previously. The apparent mass shift is small in magnitude but strongly dependent on the Higgs width, potentially allowing for a measurement of, or bound on, the width itself. In the H(→γγ)+2 jets channel, the VBF and GF contributions generate shifts of opposite signs which largely cancel, depending on the sets of cuts used, to as little as 5 MeV (toward a lower Higgs mass). The small magnitude of the shift makes this channel a good reference mass for measuring the inclusive mass shift of around 60 MeV in the Standard Model.
