Seminar:- Stochastic Quantization of General Relativity: Multiplicative Noise and Time-Intermittency at the Event Horizon
The speaker will present some recent results regarding the Stochastic Quantization(SQ) of General Relativity which leverages a stochastic process in order to recover the usual path-integral in the equilibrium limit. Hinging on the Ricci-flow, he and his team propose a new SQ formulation with multiplicative noise, yielding some non-trivial results:
(i) an emergent cosmological constant,
(ii) a non-vanishing Wheeler-DeWitt and a forced Navier-Stokes equation in ADM representation,
(iii) the KardarParisi-Zhang equation for a black hole metric, possibly yielding intermittent fluctuations.
Based on these assumptions the speaker will consider the possibility to constrain the theory from the multi-fractal analysis of the time sequences of gravitational waves signal from black-holes mergers.
