Emergent activity powers a path to chaos for pairs of acoustically trapped spheres
Matthew K. Gronert, Ben Cao, Ella M. King +1
Pairs of spheres sharing an acoustic trap sometimes spin intermittently despite having no self-propulsion, no obvious power source, and no symmetry-breaking mechanism, switching be…
Nonreciprocal wave-mediated interactions power a classical time crystal
Mia C. Morrell, Leela Elliott, David G. Grier
An acoustic standing wave acts as a lattice of evenly spaced potential energy wells for sub-wavelength-scale objects. Trapped particles interact with each other by exchanging waves…
Scattered waves fuel emergent activity
Ella M. King, Mia C. Morrell, Jacqueline B. Sustiel +3
Active matter taps into external energy sources to power its own processes. Systems of passive particles ordinarily lack this capacity, but can become active if the constituent par…
Complex Dynamics of an Acoustically Levitated Fluid Droplet Captured by a Low-Order Immersed Boundary Method
Jacqueline B. Sustiel, David G. Grier
We present a novel immersed boundary method that implements acoustic perturbation theory to model an acoustically levitated droplet. Instead of resolving sound waves numerically, o…
