Structure Selection by Non-Conservative 3-Body Acoustic Interactions
Qinghao Mao, Heinrich M. Jaeger
Non-conservative multi-body interactions are typically associated with instabilities and activity in driven, field-mediated systems. Here we show that they can also promote stable…
Nonreciprocal multi-body interactions activate liquid state of acoustically levitated particle ensembles
Nina M. Brown, Heinrich M. Jaeger
Nonreciprocal forces are often a consequence of asymmetry in the properties of the interacting objects. However. even if all objects are identical and isotropic, and the pairwise i…
Irregular Metamaterial Networks
Thomas P. Wytock, Chiara Daraio, Heinrich M. Jaeger +4
Metamaterials can achieve exceptional functionality through careful engineering of their mesoscale structure. Although appropriately introduced irregularities can be advantageous,…
Dicovering the emergent nonlinear dynamics of acoustically levitated cube clusters
Annie Z. Xia, Melody X. Lim, Jason Z. Kim +2
The complex behavior of many natural and engineered systems emerges from the interaction of a small number of effective degrees of freedom. Discovering the physical basis of the in…
Non-reciprocity and multibody interactions in acoustically levitated particle systems: A three body problem
Brady Wu, Qinghao Mao, Bryan VanSaders +1
In active fluids and active solids the constituents individually generate movement by each extracting energy from their environment or from their own source. Non-reciprocal interac…
Tunable mechanical properties and air-based lubrication in an acoustically levitated granular material
Nina M. Brown, Bryan VanSaders, Jason M. Kronenfeld +2
Cohesive granular materials are found in many natural and industrial environments, but experimental platforms for exploring the innate mechanical properties of these materials are…
Strain stiffening due to stretching of entangled particles in random packings of granular materials
Eric Brown, Kevin A. Mitchell, Alice Nasto +2
Stress-strain relations for random packings of entangling chains under triaxial compression can exhibit strain stiffening and sustain stresses several orders-of-magnitude beyond ty…
Direct measurement of forces in air-based acoustic levitation systems
Nina M. Brown, Bryan VanSaders, Jason M. Kronenfeld +2
Acoustic levitation is frequently used for non-contact manipulation of objects and to study the impact of microgravity on physical and biological processes. While the force field p…
Acoustic manipulation of multi-body structures and dynamics
Melody X. Lim, Bryan VanSaders, Heinrich M. Jaeger
Sound can exert forces on objects of any material and shape. This has made the contactless manipulation of objects by intense ultrasound a fascinating area of research with wide-ra…
Memory Effects in Granular Material
Christophe Josserand, Alexei Tkachenko, Daniel M. Mueth +1
We present a combined experimental and theoretical study of memory effects in vibration-induced compaction of granular materials. In particular, the response of the system to an ab…
Compaction of Rods: Relaxation and Ordering in Vibrated, Anisotropic Granular Material
Fernando X. Villarruel, Benjamin E. Lauderdale, Daniel M. Mueth +1
We report on experiments to measure the temporal and spatial evolution of packing arrangements of anisotropic, cylindrical granular material, using high-resolution capacitive monit…
