    • A First-Principles Model of Early Evolution: Emergence of Gene Families, Species, and Preferred Protein Folds 

      Chen, Peiqiu; Zeldovich, Konstantin B.; Shakhnovich, Eugene; Shakhnovich, Boris E. (Public Library of Science, 2007)
      In this work we develop a microscopic physical model of early evolution where phenotype—organism life expectancy—is directly related to genotype—the stability of its proteins in their native conformations—which can be ...

    • Theory of quantum impurities in spin liquids 

      Kolezhuk, Alexei; Sachdev, Subir; Biswas, Rudro R.; Chen, Peiqiu (American Physical Society, 2006)
      We describe spin correlations in the vicinity of a generalized impurity in a wide class of fractionalized spin liquid states. We argue that the primary characterization of the impurity is its electric charge under the gauge ...
