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…
Spectral holographic trapping: Creating dynamic force landscapes with polyphonic waves
Mia C. Morrell, Julianne Lee, David G. Grier
Acoustic trapping uses forces exerted by sound waves to transport small objects along specified trajectories in three dimensions. The structure of the acoustic force landscape is g…
Acoustodynamic mass determination: Accounting for inertial effects in acoustic levitation of granular materials
Mia C. Morrell, David G. Grier
Acoustic traps use forces exerted by sound waves to confine and transport small objects. The dynamics of an object moving in the force landscape of an acoustic trap can be signific…
