Fast radiation mediated shocks and supernova shock breakouts (2009)
Katz, Boaz, Budnik, Ran, Waxman, Eli
We present a simple analytic model for the structure of non-relativistic and relativistic radiation mediated shocks. At shock velocities \beta_s\equiv v_s/c\gtrsim 0.1, the shock transition region is...
The energy production rate & the generation spectrum of UHECRs (2008)
Katz, Boaz, Budnik, Ran, Waxman, Eli
We derive simple analytic expressions for the flux and spectrum of ultra-high energy cosmic-rays (UHECRs) predicted in models where the CRs are protons produced by extra-Galactic sources. For a...
Low Energy Singlets in the Heisenberg Kagome Antiferromagnet (2004)
The spin half Heisenberg antiferromagnet on the Kagome lattice, is mapped by Contractor Renormalization to a Spin-Pseudospin Hamiltonian on the triangular superlattice. Variationally, we find a...
