Corrections to the Saffman-Delbruck mobility for membrane bound proteins
Ali Naji, Alex J. Levine, Philip A. Pincus
Recent experiments by Y. Gambin et al. [PNAS 103, 2098 (2006)] have called into question the applicability of the Saffman-Delbruck diffusivity for proteins embedded in the lipid bi…
Buckling and force propagation along intracellular microtubules
Moumita Das, Alex J. Levine, F. C. MacKintosh
Motivated by recent experiments showing the buckling of microtubules in cells, we study theoretically the mechanical response of, and force propagation along elastic filaments embe…
Rheology of two-dimensional F-actin networks associated with a lipid interface
R. Walder, A. Levine, M. Dennin
We report on the surface rheology of cross-linked F-actin networks associated with a lipid monolayer at the air-water interface of a Langmuir monolayer. The rheological measurement…
Nanorheology of viscoelastic shells: Applications to viral capsids
Tatiana Kuriabova, Alex Levine
We study the microrheology of nanoparticle shells [Dinsmore et al. Science 298, 1006 (2002)] and viral capsids [Ivanovska et al. PNAS 101, 7600 (2004)] by computing the mechanical…
The effect of curvature and topology on membrane hydrodynamics
Mark L. Henle, R. McGorty, A. D. Dinsmore +1
We study the mobility of extended objects (rods) on a spherical liquid-liquid interface to show how this quantity is modified in a striking manner by both the curvature and the top…
Temperature dependence of coherent oscillations in Josephson phase qubits
J. Lisenfeld, A. Lukashenko, M. Ansmann +2
We experimentally investigate the temperature dependence of Rabi oscillations and Ramsey fringes in superconducting phase qubits driven by microwave pulses. In a wide range of temp…
