Saddle-splay screening and chiral symmetry breaking in toroidal nematics
Vinzenz Koning, Benjamin C. van Zuiden, Randall D. Kamien +1
We present a theoretical study of director fields in toroidal geometries with degenerate planar boundary conditions. We find spontaneous chirality: despite the achiral nature of ne…
Shear shocks in fragile networks
Stephan Ulrich, Nitin Upadhyaya, Bas van Opheusden +1
A minimal model for studying the mechanical properties of amorphous solids is a disordered network of point masses connected by unbreakable springs. At a critical value of its mean…
Soliton attenuation and emergent hydrodynamics in fragile matter
N. Upadhyaya, L. R. Gomez, V. Vitelli
Disordered packings of soft grains are fragile mechanical systems that loose rigidity upon lowering the external pressure towards zero. At zero pressure, we find that any infinites…
Soft quantum vibrations of PT-symmetric nonlinear ion chain
Philipp Strack, Vincenzo Vitelli
We theoretically study the quantum dynamics of transverse vibrations of a one-dimensional chain of trapped ions in harmonic potentials interacting via a Reggeon-type cubic nonlinea…
