Shape-space dynamics and geometric pattern formation in nonreciprocal slender bodies
Balázs Németh, Mohamed Warda, Ronojoy Adhikari
Nonreciprocal interactions in active solids violate action-reaction symmetry and produce a net response to strain. Assuming invariance under Euclidean symmetries, we derive a shape…
Geometric Field Theory for Elastohydrodynamics of Cosserat Rods
Mingjia Yan, Mohamed Warda, Balázs Németh +2
Slender structures are ubiquitous in biological and physical systems, from bacterial flagella to soft robotic arms. The Cosserat rod provides a mathematical framework for slender b…
Nonreciprocal constitutive laws for oriented active solids
Balázs Németh, Takuya Kobayashi, Ronojoy Adhikari
We present an overdamped continuum description of oriented active solids in which interactions respect the symmetries of space but do not obey the principle of action and reaction.…
Paramagnetism in spherically confined charged active matter
Balázs Németh, Ronojoy Adhikari
The celebrated theorem of Bohr and van Leeuwen guarantees that a classical charged system cannot have a magnetization in thermal equilibrium. Quantum mechanically, however, a diama…
