Information loss under coarse-graining: a geometric approach
Archishman Raju, Benjamin B. Machta, James P. Sethna
We use information geometry, in which the local distance between models measures their distinguishability from data, to quantify the flow of information under the renormalization g…
Finding stability domains and escape rates in kicked Hamiltonians
Archishman Raju, Sayan Choudhury, David L. Rubin +2
We use an effective Hamiltonian to characterize particle dynamics and find escape rates in a periodically kicked Hamiltonian. We study a model of particles in storage rings that is…
Normal form for renormalization groups
Archishman Raju, Colin B. Clement, Lorien X. Hayden +4
The results of the renormalization group are commonly advertised as the existence of power law singularities near critical points. The classic predictions are often violated and lo…
