Unified Hydrodynamic Analogue of Aharonov-Bohm and Lense-Thirring Effects
Aditya Singh, Joseph Samuel, Chien-chia Liu +3
We show that surface waves in a draining-bathtub vortex provide a hydrodynamic realization of both Aharonov-Bohm phase shifts and Lense-Thirring frame dragging within a single syst…
Dislocation dynamics on deformable surfaces
Marcello De Donno, Luiza Angheluta, Marco Salvalaglio
We develop a fully coupled theoretical description of dislocation dynamics on deformable crystalline surfaces, using continuum modeling and the amplitude-phase-field crystal (APFC)…
Topological interactions in vortex-wave collisions in Bose-Einstein condensates
Vebjørn Ãvereng, Andrew Baggaley, Luiza Angheluta
We study vortex-vortex and vortex-wave collisions in two-dimensional weakly interacting Bose-Einstein condensates, processes that play a central role in decaying quantum turbulence…
Spontaneous elongation of 3D gastruloids from local cell polarity alignment
Richard D. J. G. Ho, Endre J. L. Mossige, Sergei Ponomartcev +6
Gastruloids are 3D stem cell aggregate models for early embryogenesis that provide a unique platform to study how collective cell dynamics drive tissue symmetry breaking and axial…
Modeling dislocations in quasicrystals through amplitude equations
Marcello De Donno, Luiza Angheluta, Marco Salvalaglio
Quasicrystals (QCs) are a class of aperiodic ordered structures that emerge in various systems, from metallic alloys to soft matter and driven non-equilibrium systems. Within a mes…
Topological defects in polar active matter
Luiza Angheluta, Anna LÃ¥ng, Emma LÃ¥ng +1
Polar active matter - including animal herds, aggregates of motile cells and active colloids - often forms coordinated migration patterns, such as flocking. This orderly motion can…
