Network Renormalization
Andrea Gabrielli, Diego Garlaschelli, Subodh P. Patil +1
The renormalization group (RG) is a powerful theoretical framework developed to consistently transform the description of configurations of systems with many degrees of freedom, al…
Primordial Gravitational Wave Probes of Non-Standard Thermal Histories
Annet Konings, Mariia Marinichenko, Oleksii Mikulenko +1
Primordial gravitational waves propagate almost unimpeded from the moment they are generated to the present epoch. Nevertheless, they are subject to convolution with a non-trivial…
Hadamard Regularization of the Graviton Stress Tensor
Anna Negro, Subodh P. Patil
We present the details for the covariant renormalization of the stress tensor for vacuum tensor perturbations at the level of the effective action, adopting Hadamard regularization…
An Étude on the Regularization and Renormalization of Divergences in Primordial Observables
Anna Negro, Subodh P. Patil
Many cosmological observables of interest derive from primordial vacuum fluctuations evolved to late times. These observables represent statistical draws from some underlying quant…
