      Sinitsyn, N. A.; MacDonald, A. H.; Jungwirth, T.; Dugaev, V. K.; Sinova, Jairo. (American Physical Society, 2007)
      The anomalous Hall effect (AHE) is a consequence of spin-orbit coupling in a ferromagnetic metal and related primarily to density-matrix response to an electric field that is off-diagonal in band index. For this reason ...

    • Antilambda Enhancement in Ultrarelativistic Heavy-Ion Collisions 
      Ko, Che Ming; Asakawa, M.; Levai, P. (American Physical Society, 1992)
      In the Walecka model, the antilambda mass in dense nuclear matter is smaller than its value in free space. This reduces the threshold for antilambda production in dense matter that forms in the compression stage of ...
