    • Emergent Dark Matter, Baryon, and Lepton Numbers 

      Cui, Yanou; Randall, Lisa; Shuve, Brian James (Springer, 2011)
      We present a new mechanism for transferring a pre-existing lepton or baryon asymmetry to a dark matter asymmetry that relies on mass mixing which is dynamically induced in the early universe. Such mixing can succeed with ...

      Chaisson, Eric J. (MDPI AG, 2015)
      Nature’s many complex systems—physical, biological, and cultural—are islands of low-entropy order within increasingly disordered seas of surrounding, high-entropy chaos. Energy is a principal facilitator of the rising ...

      Nevins, Andrew Ira; Pesetsky, David; Rodrigues, Cilene (Linguistic Society of America, 2009)
      Everett (2005) has claimed that the grammar of Pirahã is exceptional in displaying 'inexplicable gaps', that these gaps follow from a cultural principle restricting communication to 'immediate experience', and that this ...

      Sachdev, Subir; Müller, Markus (Institute of Physics, 2009)
      Many condensed matter experiments explore the finite temperature dynamics of systems near quantum critical points. Often, there are no well-defined quasiparticle excitations, and so quantum kinetic equations do not describe ...
