Field theory for mechanical criticality in disordered fiber networks
Sihan Chen, Tomer Markovich, Fred C. MacKintosh
Strain-controlled criticality governs the elasticity of jamming and fiber networks. While the upper critical dimension of jamming is believed to be =2, non mean-field exponent…
Effective Medium Theory for Mechanical Phase Transitions of Fiber Networks
Sihan Chen, Tomer Markovich, Fred C. MacKintosh
Networks of stiff fibers govern the elasticity of biological structures such as the extracellular matrix of collagen. These networks are known to stiffen nonlinearly under shear or…
Non-affine deformation of semiflexible polymer and fiber networks
Sihan Chen, Tomer Markovich, Fred C. MacKintosh
Networks of semiflexible or stiff polymers such as most biopolymers are known to deform inhomogeneously when sheared. The effects of such non-affine deformation have been shown to…
Motor-free contractility of active biopolymer networks
Sihan Chen, Tomer Markovich, Fred C. MacKintosh
Contractility in animal cells is often generated by molecular motors such as myosin, which require polar substrates for their function. Motivated by recent experimental evidence of…
Non-linear stress relaxation of transient-crosslinked biopolymer networks
Sihan Chen, Chase P. Broedersz, Tomer Markovich +1
A long standing puzzle in the rheology of living cells is the origin of the experimentally observed long time stress relaxation. The mechanics of the cell is largely dictated by th…
Motor-free Contractility in Active Gels
Sihan Chen, Tomer Markovich, F. C. MacKintosh
Animal cells form contractile structures to promote various functions, from cell motility to cell division. Force generation in these structures is often due to molecular motors su…
