The modular Hamiltonian in asymptotically flat spacetime conformal to Minkowski
Claudio Dappiaggi, Vincenzo Morinelli, Gerardo Morsella +1
We consider a four-dimensional globally hyperbolic spacetime conformal to Minkowski spacetime, together with a massless, conformally coupled scalar field. Using a bulk-to-b…

Conservation Law and Trace Anomaly for the Stress Energy Tensor of a Self-Interacting Scalar Field
Beatrice Costeri, Claudio Dappiaggi, Michele Goi
We consider a self-interacting, massive, real scalar field on a four-dimensional globally hyperbolic spacetime and the associated stress-energy tensor. Using techniques proper of t…

An algebraic correspondence between stochastic differential equations and the Martin-Siggia-Rose formalism
Alberto Bonicelli, Claudio Dappiaggi, Nicolò Drago
In the realm of complex systems, dynamics is often modeled in terms of a non-linear, stochastic, ordinary differential equation (SDE) with either an additive or a multiplicative Ga…
