    • Frustration and multicriticality in the antiferromagnetic spin-1 chain 

      Pixley, J.H.; Shashi, Aditya; Nevidomskyy, Andriy H. (2014)
      The antiferromagnetic spin-1 chain has a venerable history and has been thought to be well understood. Here, we show that inclusion of both next-nearest-neighbor (α) and biquadratic (β)interactions results in a rich phase ...
    • Frustration in biomolecules 

      Ferreiro, Diego U.; Komives, Elizabeth A.; Wolynes, Peter G. (2014)
      Biomolecules are the prime information processing elements of living matter. Most of these inanimate systems are polymers that compute their own structures and dynamics using as input seemingly random character strings of ...

      Single-wall carbon nanotubes provide ideal model one-dimensional (1-D) condensed matter systems in which to address fundamental questions in many-body physics, while, at the same time, they are leading candidates for ...
    • Funneling and frustration in the energy landscapes of some designed and simplified proteins 

      Truong, Ha H.; Kim, Bobby L.; Schafer, Nicholas P.; Wolynes, Peter G. (2013)
      We explore the similarities and differences between the energy landscapes of proteins that have been selected by nature and those of some proteins designed by humans. Natural proteins have evolved to function as well as ...
    • Gapless topological Fulde-Ferrell superfluidity induced by an in-plane Zeeman field 

      Hu, Hui; Dong, Lin; Cao, Ye; Pu, Han; Liu, Xia-Ji (2014)
      Topological superfluids are recently discovered quantum matter that hosts topologically protected gapless edge states known as Majorana fermions—exotic quantum particles that act as their own antiparticles and obey non-Abelian ...
