    Kim, Ji-Hee; Noe, G. Timothy II; McGill, Stephen A.; Wang, Yongrui; Wojcik, Aleksander K.; Belyanin, Alexey A.; Kono, Junichiro (2013)
    Nonequilibrium can be a source of order. This rather counterintuitive statement has been proven to be true through a variety of fluctuation-driven, self-organization behaviors exhibited by out-of-equilibrium, many-body ...

    Rau, C.; Liu, C.; Schmalzbauer, A.; Xing, G. (1986)
    Electron-capture spectroscopy has been used to investigate magnetic order at the topmost atomic layer of atomically clean and flat (100) surfaces of bulk paramagnetic vanadium. From low-energy electron diffraction measurements, ...
  • Ferromagnetic order at surfaces of ultrathin epitaxial fcc γ-Fe(111)p(11) films on Cu(111) 

    Rau, C.; Schneider, C.; Xing, G.; Jamison, K. (1986)
    Electron-capture spectroscopy has been used to investigate long-ranged and short-ranged two-dimensional magnetic order at free (uncoated) surfaces of homogeneous (island-free), ultrathin fcc γ-Fe(111)(1×1) films pseudomorphically ...
  • Finite population size effects in quasispecies models with single-peak fitness landscape 

    Saakian, David B.; Deem, Michael W.; Hu, Chin-Kun (2012-04)
    We consider finite population size effects for Crow-Kimura and Eigen quasispecies models with single-peak fitness landscape. We formulate accurately the iteration procedure for the finite population models, then derive ...

    Dyke, P.; Pollack, S.E.; Hulet, R.G. (2013)
    We have measured the binding energy of 7Li Feshbach molecules deep into the nonuniversal regime by associating atoms in a Bose-Einstein condensate with a modulated magnetic field. We extract the scattering length from these ...

    Capraro, Dominique T.; Gosavi, Shachi; Roy, Melinda; Onuchic, José N.; Jennings, Patricia A. (2012-06)
    Interleukin-1b (IL-1b) is the cytokine crucial to inflammatory and immune response. Two dominant routes are populated in the folding to native structure. These distinct routes are a result of the competition between early ...
  • Formation and propagation of matter-wave soliton trains 

    Strecker, Kevin E.; Partridge, Guthrie B.; Truscott, Andrew G.; Hulet, Randall G. (2002)
    Attraction between the atoms of a Bose-Einstein condensate renders it unstable to collapse, although a condensate with a limited number of atoms [1] can be stabilized [2] by confinement in an atom trap. However, beyond ...
  • Free energy landscape for the binding process of Huperzine A to acetylcholinesterase 

    Bai, Fang; Xu, Yechun; Chen, Jing; Liu, Qiufeng; Gu, Junfeng; Wang, Xicheng; Ma, Jianpeng; Li, Honglin; Onuchic, José N.; Jiang, Hualiang (2012)
    Drug-target residence time (t = 1/koff, where koff is the dissociation rate constant) has become an important index in discovering betteror best-in-class drugs. However, little effort has been dedicated to developing ...
  • Freeze-out dynamics via charged kaon femtoscopy in √sNN=200 GeV central Au + Au collisions 

    STAR Collaboration; Butterworth, J.; Eppley, G.; Geurts, F.; Llope, W.J.; McDonald, D.; Roberts, J.B.; Xin, K.; Yepes, P. (2013)
    We present measurements of three-dimensional correlation functions of like-sign, low-transverse-momentum kaon pairs from √sNN=200 GeV Au+Au collisions. A Cartesian surface-spherical harmonic decomposition technique was ...
  • 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 ...
  • Fundamental optical processes in armchair carbon nanotubes 

    Haroz, Erik H.; Duque, Juan G.; Tu, Xiaomin; Zheng, Ming; Walker, Angela R. Hight; Hauge, Robert H.; Doorn, Stephen K.; Kono, Junichiro (2013)
    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 ...
  • Genomics-aided structure prediction 

    Sulkowska, Joanna I.; Morcos, Faruck; Weigt, Martin; Hwa, Terence; Onuchic, José N. (2012)
    We introduce a theoretical framework that exploits the everincreasing genomic sequence information for protein structure prediction. Structure-based models are modified to incorporate constraints by a large number of ...

    Sackett, C.A.; Stoof, H.T.C.; Hulet, R.G. (1998)
    We consider the dynamics of a quantum degenerate trapped gas of 7Li atoms. Because the atoms have a negative s-wave scattering length, a Bose condensate of 7Li becomes mechanically unstable when the number of condensate ...
