Mutual information as a measure of renormalizability
Brenden Bowen, Albert Farah, Spasen Chaykov +1
Renormalization is an essential technique in field-theoretic descriptions of natural phenomena, where the absence of a UV-complete description yields an abundance of divergent quan…
Thermalization and localization in a discretized quantum field theory
Spasen Chaykov, Brenden Bowen, Nishant Agarwal
Localization marks the breakdown of thermalization in subregions of quantum many-body systems in the presence of sufficiently large disorder. In this paper, we use numerical techni…
Loop corrections in Minkowski spacetime away from equilibrium. Part II. Finite-time results
Spasen Chaykov, Nishant Agarwal, Sina Bahrami +1
Loop corrections to finite-time correlation functions in quantum field theories away from equilibrium can be calculated using the in-in path integral approach. In this paper, we ca…
Loop corrections in Minkowski spacetime away from equilibrium. Part I. Late-time resummations
Spasen Chaykov, Nishant Agarwal, Sina Bahrami +1
Loop corrections to unequal-time correlation functions in Minkowski spacetime exhibit secular growth due to a breakdown of time-dependent perturbation theory. This is analogous to…
Alternative gravity rotation curves for the Little Things Survey
James G. O'Brien, Thomas L. Chiarelli, Jeremy Dentico +4
Galactic rotation curves have proven to be the testing ground for dark matter bounds in spiral galaxies of all morphologies. Dwarf galaxies serve as an increasingly interesting cas…
