A bilayer cellular Potts model of epithelial docking
Troy Singletary, Andrea James, Tyler A. Engstrom
Fusion of two epithelial cell sheets brought together in a bilayer configuration is a common step in animal morphogenesis, yet, in contrast to other epithelial fusion processes suc…
Conservative yet constitutively odd elasticity in prestressed metamaterials
Tyler A. Engstrom, Daniel M. Sussman
We introduce a design principle for mechanical metamaterials based on "odd elasticity, once removed." By revisiting classic results relating the variation of Cauchy stress and Lagr…
Dynamics of certain Euler-Bernoulli rods and rings from a minimal coupling quantum isomorphism
T. A. Engstrom
In some parameter and solution regimes, a minimally coupled nonrelativistic quantum particle in 1d is isomorphic to a much heavier, vibrating, very thin Euler-Bernoulli rod in 3d,…
The quantum character of buckling instabilities in thin rods
T. A. Engstrom
Here the buckling of inextensible rods due to axial body forces is mapped to 1d, nonrelativistic, time-independent quantum mechanics. Focusing on the pedagogical case of rods confi…
Loops versus lines and the compression stiffening of cells
M. C. Gandikota, Katarzyna Pogoda, Anne van Oosten +4
Both animal and plant tissue exhibit a nonlinear rheological phenomenon known as compression stiffening, or an increase in moduli with increasing uniaxial compressive strain. Does…
Buckling without bending: a new paradigm in morphogenesis
T. A. Engstrom, Teng Zhang, A. K. Lawton +2
A curious feature of organ and organoid morphogenesis is that in certain cases, spatial oscillations in the thickness of the growing "film" are out-of-phase with the deformation of…
Compression stiffening in biological tissues: on the possibility of classic elasticity origins
T. A. Engstrom, K. Pogoda, K. Cruz +2
Compression stiffening, or an increase in shear modulus with increasing compressive strain, has been observed in recent rheometry experiments on brain, liver, and fat tissues. Here…
Surface creasing of soft elastic continua as a Kosterlitz-Thouless transition
T. A. Engstrom, J. M. Schwarz
Harnessing a model from composite materials science, we show how point-like cusped surface features arise as quasi-particle excitations, termed "ghost fibers", on the surface of a…
Crystal chemistry of three-component white dwarfs and neutron star crusts: phase stability, phase stratification, and physical properties
T. A. Engstrom, N. C. Yoder, V. H. Crespi
A systematic search for multicomponent crystal structures is carried out for five different ternary systems of nuclei in a polarizable background of electrons, representative of ac…
Microphysics of Neutron Star Outer Envelopes in the Periodized, Magnetic Thomas-Fermi Model
Tyler A. Engstrom, Vincent H. Crespi, Benjamin J. Owen +2
Static and dynamic properties of low density outer envelopes of neutron stars are calculated within the nonlinear magnetic Thomas-Fermi model, assuming degenerate electrons. A nove…
