Supersonic cracks in lattice models
(Springer, 2010-03)
We have studied cracks traveling along weak interfaces. We model them using harmonic and anharmonic forces between particles in a lattice, both in tension (Mode I) and antiplane shear (Mode III). One of our main objects ...
Real-time diagrammatic approach to current-induced forces: Application to quantum-dot based nanomotors
(American Physical Society, 2017-10-12)
In recent years there has been increasing excitement regarding nanomotors and particularly current-driven nanomotors. Despite the broad variety of stimulating results found, the regime of strong Coulomb interactions has ...
Stably stratified turbulence in the presence of large-scale forcing
(American Physical Society, 2015-07)
We perform two high-resolution direct numerical simulations of stratified turbulence for Reynolds number equal to Re ≈ 25 000 and Froude number, respectively, of Fr ≈ 0.1 and Fr ≈ 0.03. The flows are forced at large scale ...

Electrostatically actuated encased cantilevers
(Beilstein-Institut züur Forderung der Chemischen Wissenschaften, 2018-05)
Background: Encased cantilevers are novel force sensors that overcome major limitations of liquid scanning probe microscopy. By trapping air inside an encasement around the cantilever, they provide low damping and maintain ...
Cortical Tension Allocates the First Inner Cells of the Mammalian Embryo
(Cell Press, 2015-08)
Every cell in our body originates from the pluripotent inner mass of the embryo, yet it is unknown how biomechanical forces allocate inner cells in vivo. Here we discover subcellular heterogeneities in tensile forces, ...
Analysis of the Form-Function Relationship: Digging Behavior as a Case Study
(Springer, 2019-12)
Studies of functional morphology focus on species showing evident specializations, or at least some degree of divergence from the so-called “generalized phenotype.” This may have led to the proposal of the form-function ...
Thermalization and free decay in surface quasigeostrophic flows
(American Physical Society, 2012-07)
We derive statistical equilibrium solutions of the truncated inviscid surface quasigeostrophic (SQG) equations, and verify the validity of these solutions at late times in numerical simulations. The results indicate the ...
