Gravitational Aharonov-Bohm effect: theory and experiment
Zhongyou Mo, Leonardo Modesto
We study the quantum interference of two paths that enclose a slowly rotating, infinitely long, and infinitely thin cylindrical shell, using the spacetime metric induced by the gra…
Superconductive or superfluid condensation in curved spacetime
Leonardo Modesto
We provide a proof of unitarity for quantum field theory in a general spacetime. Our argument expresses the Bogoliubov transformations in terms of a unitary squeezing operator rela…
Taming singularities and chaos in conformal gravity
Jiale Gu, Leonardo Modesto, Cosimo Bambi
We hereby address the cosmological singularity problem in a general gravitational theory invariant under Weyl conformal transformations. In particular, we focus on the Bianchi IX s…
Do Black Holes Exist?
Leonardo Modesto, Edoardo Rattu
We carefully investigate, extend, and shed new light on the McVittie exact solution of Einstein's gravity (EG) with the focus on the implications in the Universe we live in. It tur…
A Quantum Superposition of Black Hole Evaporation Histories: Recovering Unitarity
Ali Akil, Lorenzo Giannelli, Leonardo Modesto +3
Black hole evaporation is one of the most striking phenomena at the interface between gravity and quantum physics. In Hawking's semi-classical treatment, where matter is quantum me…
Form factors, spectral and Källén-Lehmann representation in nonlocal quantum gravity
Fabio Briscese, Gianluca Calcagni, Leonardo Modesto +1
We discuss the conical region of convergence of exponential and asymptotically polynomial form factors and their integral representations. Then, we calculate the spectral represent…
