      Shepherd, James J.; Henderson, Thomas M.; Scuseria, Gustavo E. (2014)
      We introduce a range-separation approximation to coupled cluster doubles (CCD) theory that successfully overcomes limitations of regular CCD when applied to the uniform electron gas. We combine the short-range ladder channel ...
    • Rapidity correlations in the RHIC Beam Energy Scan Data 

      Jowzaee, Sedigheh; STAR Collaboration (2017)
      A pair-normalized two-particle covariance versus the rapidity of the two particles, called R2, was originally studied in ISR and FNAL data in the 1970's. This variable has recently seen renewed interest for the study of ...

      Yang, Jian; Wolf, Richard A.; Toffoletto, Frank R.; Sazykin, Stanislav; Wang, Chih-Ping (2014)
      Plasma sheet transport is bimodal, consisting of both large-scale adiabatic convection and intermittent bursty flows in both earthward and tailward directions. We present two comparison simulations with the Rice Convection ...
