Odd viscosity and odd elasticity

M Fruchart, C Scheibner, V Vitelli - Annual Review of …, 2023‏ - annualreviews.org
Elasticity typically refers to a material's ability to store energy, whereas viscosity refers to a
material's tendency to dissipate it. In this review, we discuss fluids and solids for which this is …

Non-Hermitian band topology and skin modes in active elastic media

C Scheibner, WTM Irvine, V Vitelli - Physical Review Letters, 2020‏ - APS
Solids built out of active components can exhibit nonreciprocal elastic coefficients that give
rise to non-Hermitian wave phenomena. Here, we investigate non-Hermitian effects present …

Emergent phenomena in chiral active matter

J Mecke, JO Nketsiah, R Li, Y Gao - National Science Open, 2024‏ - nso-journal.org
In recent years, there has been growing interest in the study of chiral active materials, which
consist of building blocks that show active dynamics featuring chiral symmetry breaking, eg …

Giant, magnet-free, and room-temperature Hall-like heat transfer

L Xu, J Liu, G Xu, J Huang, CW Qiu - … of the National Academy of Sciences, 2023‏ - pnas.org
Thermal chirality, generically referring to the handedness of heat flux, provides a significant
possibility for modern heat control. It may be realized with the thermal Hall effect yet at the …

Arrested phase separation in chiral fluids of colloidal spinners

H Massana-Cid, D Levis, RJH Hernández… - Physical Review …, 2021‏ - APS
We investigate phase separation in a chiral fluid, made of spinning ferromagnetic colloids
that interact both via hydrodynamic and dipolar forces and collectively organize into …

Stokes flows in three-dimensional fluids with odd and parity-violating viscosities

T Khain, C Scheibner, M Fruchart… - Journal of Fluid …, 2022‏ - cambridge.org
The Stokes equation describes the motion of fluids when inertial forces are negligible
compared with viscous forces. In this article, we explore the consequence of parity-violating …

Active viscoelasticity of odd materials

D Banerjee, V Vitelli, F Jülicher, P Surówka - Physical Review Letters, 2021‏ - APS
The mechanical response of active media ranging from biological gels to living tissues is
governed by a subtle interplay between viscosity and elasticity. We generalize the canonical …

Hall viscosity in quantum systems with discrete symmetry: point group and lattice anisotropy

P Rao, B Bradlyn - Physical Review X, 2020‏ - APS
Inspired by recent experiments on graphene, we examine the nondissipative viscoelastic
response of anisotropic two-dimensional quantum systems. We pay particular attention to …

Hydrodynamic lift of a two-dimensional liquid domain with odd viscosity

Y Hosaka, S Komura, D Andelman - Physical Review E, 2021‏ - APS
We discuss hydrodynamic forces acting on a two-dimensional liquid domain that moves
laterally within a supported fluid membrane in the presence of odd viscosity. Since active …

Odd Cosserat elasticity in active materials

P Surówka, A Souslov, F Jülicher, D Banerjee - Physical Review E, 2023‏ - APS
Stress-strain constitutive relations in solids with an internal angular degree of freedom can
be modeled using Cosserat (also called micropolar) elasticity. In this paper, we explore …
