Fractions and Fakeons in Quantum Field Theory
Damiano Anselmi
We investigate formulations of quantum field theories whose kinetic terms involve fractional or continuous powers of the d'Alembert operator. The primary requirements are perturbat…
Classicized dynamics and initial conditions in field theories with fakeons
Damiano Anselmi, Gianluca Calcagni
Theories with purely virtual particles (fakeons) do not possess a classical action in the strict sense, but rather a "classicized" one, obtained by integrating out the fake particl…
Amplitude prescriptions in field theories with complex poles
Damiano Anselmi, Fabio Briscese, Gianluca Calcagni +1
In the context of field theories with complex poles, we scrutinize four inequivalent ways of defining the scattering amplitudes, each forfeiting one or more tenets of standard quan…
Visions in Quantum Gravity
Luca Buoninfante, Benjamin Knorr, K. Sravan Kumar +36
To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is cr…
Quantum gravity with purely virtual particles from asymptotically local quantum field theory
Damiano Anselmi
We investigate the relationship between nonlocal and local quantum field theories, and search for a viable notion of "local limit" to relate the unitary models. In Euclidean space…
Gauge theories and quantum gravity in a finite interval of time, on a compact space manifold
Damiano Anselmi
We study gauge theories and quantum gravity in a finite interval of time , on a compact space manifold . The initial, final and boundary conditions are formulated in gauge in…
