Stress-free BCS pairing in color superconductors is impossible
Krishna Rajagopal, Andreas Schmitt
Cold, asymptotically dense three-flavor quark matter is in the color-flavor locked (CFL) phase, in which all quarks pair in a particularly symmetric fashion. At smaller densities,…
An AdS/CFT Calculation of Screening in a Hot Wind
Hong Liu, Krishna Rajagopal, Urs Achim Wiedemann
One of the challenges in relating experimental measurements of the suppression in the number of J/ψmesons produced in heavy ion collisions to lattice QCD calculations is that where…
The Crystallography of Strange Quark Matter
Krishna Rajagopal, Rishi Sharma
Cold three-flavor quark matter at large (but not asymptotically large) densities may exist as a crystalline color superconductor. We explore this possibility by calculating the gap…
The Crystallography of Three-Flavor Quark Matter
Krishna Rajagopal, Rishi Sharma
We analyze and compare candidate crystal structures for the crystalline color superconducting phase that may arise in cold, dense but not asymptotically dense, three-flavor quark m…
Calculating the Jet Quenching Parameter from AdS/CFT
Hong Liu, Krishna Rajagopal, Urs Achim Wiedemann
Models of medium-induced radiative parton energy loss account for the strong suppression of high-pT hadron spectra in GeV Au-Au collisions at RHIC in terms of a…
The Stability of Strange Star Crusts and Strangelets
Mark G. Alford, Krishna Rajagopal, Sanjay Reddy +1
We construct strangelets, taking into account electrostatic effects, including Debye screening, and arbitrary surface tension sigma of the interface between vacuum and quark matter…
