We present a new mechanism for triggering the flocking transition in epithelia, involving extensile polar defects and domain walls. Very happy to share this work, done in great collaboration with the @luizaangheluta.bsky.social group.

Topology made visible in a spinning fluid
Standing waves in a draining vortex bathtub form quantized nodal structures-a wave topology set by the vortex, analogous to Aharonov–Bohm effect. Collab with Mahesh M. Bandi’s lab @oistedu.bsky.social & Andrés Concha.

Wave-topology interactions lie at the heart of numerous physical phenomena, from condensed matter systems to cosmological models, exemplified by the Aharonov-Bohm effect. Drawing on its classical anal...
Transitions from quiescence to collective migration in epithelia underlie wound healing and cancer invasion, yet their physical origin remains poorly understood. Here we show that quiescent epithelial...

Quasicrystals (QCs) are a class of aperiodic ordered structures that emerge in various systems, from metallic alloys to soft matter and driven non-equ…
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 system. A static time tr...
