On the Renormalization Group Flow of Active Flocks
Kevin T. Grosvenor, Subodh P. Patil
We study the statistical field-theoretic renormalization of active flocks via the Martin-Siggia-Rose-De Dominicis-Janssen (MSRDJ) formulation of stochastic dynamics, focusing on th…
Renormalization of Interacting Random Graph Models
Alessio Catanzaro, Diego Garlaschelli, Subodh P. Patil
Random graphs offer a useful mathematical representation of a variety of real world complex networks. Exponential random graphs, for example, are particularly suited towards genera…
A General Solution for Network Models with Pairwise Edge Coupling
Alessio Catanzaro, Subodh Patil, Diego Garlaschelli
Network Models with couplings between link pairs are the simplest models for a class of networks with Higher Order interactions. In this paper we give an analytic, general solution…
Hydrodynamics without Boost-Invariance from Kinetic Theory: From Perfect Fluids to Active Flocks
Kevin T. Grosvenor, Niels A. Obers, Subodh P. Patil
We derive the hydrodynamic equations of perfect fluids without boost invariance [1] from kinetic theory. Our approach is to follow the standard derivation of the Vlasov hierarchy b…
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…
