On the Renormalization Group Flow of Active Flocks
Kevin T. Grosvenor, Subodh P. Patil
In this paper, we study the statistical field-theoretic renormalization of active flocks via the MSRDJ action formulation for stochastic systems, focusing on the Toner-Tu theory of…
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…
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…
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…
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…
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…
