On more general Gibbons-Hawking-York boundary terms for f(R) gravity
Federico Scali, Sergio Luigi Cacciatori, Matteo Galaverni +1
More general boundary conditions are introduced - with respect to known literature - which produce a well-posed stationary action principle in gravity. These conditions enco…
Black Holes, Gravitational Waves and Space-Time Singularities Lemaitre Conference 2024
Massimo Bianchi, Sergio Luigi Cacciatori, Matteo Galaverni +2
This editorial introduces the topical collection arising from the Lemaitre Conference 2024 - the second in a series of meetings dedicated to the scientific legacy of Georges Lemait…
Local observers in stationary axisymmetric dust spacetimes
Matteo Fontana, Sergio Luigi Cacciatori, Roberto Peron
In this work, we construct a locally inertial reference system adapted to a geodesic observer in stationary, axisymmetric dust solutions of the Einstein equations employed as effec…
Effective potentials for de Sitter and anti de Sitter quantum fields
Alfio Bonanno, Sergio Luigi Cacciatori, Ugo Moschella
We derive a systematic treatment of one-loop effective potentials for interacting scalar fields in curved spacetimes, providing a general formula valid in arbitrary geometries and…
Minimum spacetime length and the thermodynamics of spacetime
Valeria Rossi, Sergio Luigi Cacciatori, Alessandro Pesci
Theories of emergent gravity have established a deep connection between entropy and the geometry of spacetime by looking at the latter through a thermodynamic lens. In this framewo…
A gauge theory of complex adaptive systems
Gueorgui M. Mihaylov, Sergio L. Cacciatori
We introduce a geometric construction of a gauge field theory of a complex adaptive system. It is based on a suitable simplicial formulation of a discrete geometry that manifests r…
