Steepest growth of the power spectrum and primordial black holes
Christian T. Byrnes, Philippa S. Cole, Subodh P. Patil
We derive analytic bounds on the shape of the primordial power spectrum in the context of single-field inflation. In particular, the steepest possible growth has a spectral index o…
Tensor Bounds on the Hidden Universe
Adrian del Rio, Ruth Durrer, Subodh P. Patil
During single clock inflation, hidden fields (i.e. fields coupled to the inflaton only gravitationally) in their adiabatic vacua can ordinarily only affect observables through virt…
Renormalization of Sparse Disorder in the Ising Model
Yaneer Bar-Yam, Subodh P. Patil
We consider the renormalization of quenched bond disorder in the Ising model in the limit that it is sparse -- highly localized and vanishing in the thermodynamic limit. We begin i…
