Elastodynamics from Eulerian Poisson-bracket formalism: application to chiral odd solids
Cheng-Tai Lee, Tomer Markovich
The Poisson-bracket (PB) formalism is widely used to derive dynamics of coarse-grained (CG) fields to capture large-scale physics, extending the role of PBs in classical particle m…
Non-Hermitian chiral surface waves in disordered odd solids
Cheng-Tai Lee, Tomer Markovich
Chiral surface waves are surface-localized modes that propagate unidirectionally along a boundary, enabling directed transport and minimal back-scattering. While first identified i…
Odd elasticity in disordered chiral active materials
Cheng-Tai Lee, Tom C. Lubensky, Tomer Markovich
Chiral active materials are abundant in nature, including the cytoskeleton with attached motor proteins, rotary clusters of bacterial flagella, and self-spinning starfish embryos.…
Control of active field theories at minimal dissipation
Artur Soriani, Elsen Tjhung, Étienne Fodor +1
Advances in experimental techniques enable the precise manipulation of a large variety of active systems, which constantly dissipate energy to sustain nonequilibrium phenomena with…
Chiral active fluids: what can we learn from the total momentum?
Tomer Markovich, Tom C. Lubensky
Chiral active materials are those that break both time-reversal symmetry and parity microscopically, which results in average rotation of the material's complex molecules around th…
Second Law of Thermodynamics without Einstein Relation
Benjamin Sorkin, Haim Diamant, Gil Ariel +1
Materials that are constantly driven out of thermodynamic equilibrium, such as active and living systems, typically violate the Einstein relation. This may arise from active contri…
Consistent expansion of the Langevin propagator with application to entropy production
Benjamin Sorkin, Gil Ariel, Tomer Markovich
Stochastic thermodynamics is a developing theory for systems out of thermal equilibrium. It allows to formulate a wealth of nontrivial relations among thermodynamic quantities such…
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…
Nonreciprocity and odd viscosity in chiral active fluids
Tomer Markovich, Tom C. Lubensky
Odd viscosity couples stress to strain rate in a dissipationless way. It has been studied in plasmas under magnetic fields, superfluid , quantum-Hall fluids, and recent…
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…
Stochastic Hydrodynamics of Complex Fluids: Discretisation and Entropy Production
Michael E. Cates, Étienne Fodor, Tomer Markovich +2
Many complex fluids can be described by continuum hydrodynamic field equations, to which noise must be added in order to capture thermal fluctuations. In almost all cases, the resu…
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…
Thermodynamics of active field theories: Energetic cost of coupling to reservoirs
Tomer Markovich, Étienne Fodor, Elsen Tjhung +1
The hallmark of active matter is the autonomous directed motion of its microscopic constituents driven by consumption of energy resources. This leads to the emergence of large scal…
Odd viscosity in active matter: microscopic origin and 3D effects
Tomer Markovich, Tom C. Lubensky
In common fluids, viscosity is associated with dissipation. However, when time-reversal-symmetry is broken a new type of non-dissipative `viscosity' may emerge. Recent theories and…
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…
Chiral active matter: microscopic `torque dipoles' have more than one hydrodynamic description
Tomer Markovich, Elsen Tjhung, Michael E. Cates
Many biological systems, such as bacterial suspensions and actomyosin networks, form polar liquid crystals. These systems are `active' or far-from-equilibrium, due to local forcing…
