    • Complex Ordered Patterns in Mechanical Instability Induced Geometrically Frustrated Triangular Cellular Structures 

      Kang, Sung Hoon; Shan, Sicong; Kosmrlj, Andrej; Noorduin, Wim L.; Shian, Samuel; Weaver, James C.; Clarke, David R.; Bertoldi, Katia (American Physical Society, 2014)
      Geometrical frustration arises when a local order cannot propagate throughout the space because of geometrical constraints. This phenomenon plays a major role in many systems leading to disordered ground-state configurations. ...
    • Mechanical Properties of Warped Membranes 

      Kosmrlj, Andrej; Nelson, David R. (American Physical Society, 2013)
      We explore how a frozen background metric affects the mechanical properties of planar membranes with a shear modulus. We focus on a special class of “warped membranes” with a preferred random height profile characterized ...
    • A monomer-trimer model supports intermittent glucagon fibril growth 

      Košmrlj, Andrej; Cordsen, Pia; Kyrsting, Anders; Otzen, Daniel E.; Oddershede, Lene B.; Jensen, Mogens H. (Nature Publishing Group, 2015)
      We investigate in vitro fibrillation kinetics of the hormone peptide glucagon at various concentrations using confocal microscopy and determine the glucagon fibril persistence length 60μm. At all concentrations we observe ...
    • Thermal Excitations of Warped Membranes 

      Kosmrlj, Andrej; Nelson, David R. (American Physical Society, 2014)
      We explore thermal fluctuations of thin planar membranes with a frozen spatially varying background metric and a shear modulus. We focus on a special class of D-dimensional “warped membranes” embedded in a d-dimensional ...
