      Sachdev, Subir (American Physical Society, 2012)
      Conformal field theories (CFTs) with a globally conserved U(1) charge Q can be deformed into compressible phases by modifying their Hamiltonian, H, by a chemical potential H→H-μQ. We study 2+1 dimensional CFTs upon which ...

      Brady, Timothy F.; Konkle, Talia; Alvarez, George (American Psychological Association (APA), 2009)
      The information that individuals can hold in working memory is quite limited, but researchers have typically studied this capacity using simple objects or letter strings with no associations between them. However, in the ...
    • Compressive genomics for protein databases 

      Daniels, Noah M.; Gallant, Andrew; Peng, Jian; Cowen, Lenore J.; Baym, Michael; Berger, Bonnie (Oxford University Press, 2013)
      Motivation: The exponential growth of protein sequence databases has increasingly made the fundamental question of searching for homologs a computational bottleneck. The amount of unique data, however, is not growing nearly ...
    • Compressive Sensing Based Channel Feedback Protocols for Spatially-Correlated Massive Antenna Arrays 

      Kuo, Ping-Heng; Kung, H. T.; Ting, Pang-an (Institute of Electrical and Electronics Engineers, 2012)
      Incorporating wireless transceivers with numerous antennas (such as Massive-MIMO) is a prospective way to increase the link capacity or enhance the energy efficiency of future communication systems. However, the benefits ...
