Direct Experimental Test of Conformal Invariance via Grazing Scattering: A Proposal for X-ray and Neutron Experiments
Alessandro Podo, Slava Rychkov
We propose a test of conformal invariance in critical phenomena based on the study of a two-point correlation function in the presence of a boundary. This two-point function can be…
Naturalness of vanishing black-hole tides
Julio Parra-Martinez, Alessandro Podo
We provide a symmetry argument for the vanishing and non-renormalization of static Love numbers for spherically symmetric black holes at full nonlinear order in four-dimensional Ge…
Hadamard tails from flat-space perturbation theory
Ameya Chavda, Alberto Nicolis, Alessandro Podo +1
The short-distance singular structure of the two-point function of a free scalar field in curved spacetime has a universal behavior that characterizes well-behaved states (called H…
Microcausality without Lorentz invariance
Lam Hui, Alberto Nicolis, Alessandro Podo +1
Microcausality -- the vanishing of commutators outside the lightcone -- is a fundamental property of relativistic quantum field theories. We derive its implications for two-point f…
