Orientational order on non-orientable domains
Gianmarco Spera, Axel Fotso Ndefo, Keaton J. Burns +1
We study the statistical properties of passive and active many-body systems with orientational degrees of freedom on non-orientable domains. By rephrasing topological constraints a…
Resonances in Overdamped Odd Materials
Julius Kiln, Alexander Mietke
Odd viscoelasticity arises in parity-violating nonequilibrium materials, where it leads to unconventional mechanical responses and oscillatory relaxation even in overdamped systems…
Active Fluid Patterning in Inhomogeneous Environments
Douglas MacMyn Brown, Alexander Mietke
Active stresses in biological cells and tissues drive many developmental processes. However, increasing experimental evidence suggests that additional mechanical interactions with…
Confinement-Induced Symmetry Breaking of Active Surfaces
Da Gao, Alexander Mietke, Rui Ma
The actomyosin cortex, a thin layer of a cross-linked polymer network near the cell surface, generates active forces that are responsible for cell shape changes. Many developmental…
Odd electrical circuits
Harry Walden, Alexander Stegmaier, Jörn Dunkel +1
Non-reciprocal interactions in elastic media give rise to rich non-equilibrium behaviors, but controllable experimental realizations of such odd elastic phenomena remain scarce. Bu…
Self-organized dynamics and emergent shape spaces of active isotropic fluid surfaces
Da Gao, Huayang Sun, Rui Ma +1
Theories of self-organized active fluid surfaces have emerged as an important class of minimal models for the shape dynamics of biological membranes, cells and tissues. However, du…
Rheology of suspensions of flat elastic particles
Jens Eggers, Tanniemola B. Liverpool, Alexander Mietke
We consider a suspension of non-interacting flat elastic particles in a Newtonian fluid. We model a flat shape as three beads, carried along by the flow according to Stokes' law, a…
Dynamics, scaling behavior, and control of nuclear wrinkling
Jonathan A. Jackson, Nicolas Romeo, Alexander Mietke +5
The cell nucleus is enveloped by a complex membrane, whose wrinkling has been implicated in disease and cellular aging. The biophysical dynamics and spectral evolution of nuclear w…
Odd dynamics of living chiral crystals
Tzer Han Tan, Alexander Mietke, Junang Li +6
Active crystals are highly ordered structures that emerge from the self-organization of motile objects, and have been widely studied in synthetic and bacterial active matter. Wheth…
Learning developmental mode dynamics from single-cell trajectories
Nicolas Romeo, Alasdair Hastewell, Alexander Mietke +1
Embryogenesis is a multiscale process during which developmental symmetry breaking transitions give rise to complex multicellular organisms. Recent advances in high-resolution live…
Learning hydrodynamic equations for active matter from particle simulations and experiments
Rohit Supekar, Boya Song, Alasdair Hastewell +3
Recent advances in high-resolution imaging techniques and particle-based simulation methods have enabled the precise microscopic characterization of collective dynamics in various…
Anyonic defect braiding and spontaneous chiral symmetry breaking in dihedral liquid crystals
Alexander Mietke, Jörn Dunkel
Dihedral ('-atic') liquid crystals (DLCs) are assemblies of microscopic constituent particles that exhibit -fold discrete rotational and reflection symmetries. Generalizing t…
Minimal model of cellular symmetry breaking
Alexander Mietke, V. Jemseena, K. Vijay Kumar +2
The cell cortex, a thin film of active material assembled below the cell membrane, plays a key role in cellular symmetry breaking processes such as cell polarity establishment and…
Lessons from Oxypnictide Thin Films
Silvia Haindl, Martin Kidszun, Franziska Onken +2
First experiments on the growth of oxypnictide F-doped LaFeAsO thin films indicated an incomplete normal-to-superconducting transition and offered a work programme challenging to o…
