Taming the infrared in de Sitter space: autonomous equations, stochastic approach, and Borel resummation
Alexander Kamenshchik, Polina Petriakova, Tereza Vardanyan
We investigate the divergent perturbative series of correlation functions for a massless, self-interacting scalar field in de Sitter space. First, we use our previously proposed me…
Two-time physics, Carroll symmetry and Jordan algebras
Alexander Kamenshchik, Alessio Marrani, Federica Muscolino
We describe Carroll particles with nonzero energy (i.e., particles that remain at rest) within the framework of two-time (2T) physics developed by Bars and collaborators. In a spac…
Two Times for Freudenthal
Alexander Kamenshchik, Alessio Marrani, Federica Muscolino
We investigate the algebraic structure of the two-time physics introduced some time ago by I. Bars and his co-authors, clarifying its relations with quadratic and cubic Jordan alge…
