Multistable energy landscapes for adaptive microscopic machines
Melody Xuan Lim, Zexi Liang, Gabriel Alkuino +5
The past few years have seen great strides in our ability to build synthetic microscopic machines. However, the function of such machines is often controlled directly by externally…
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…
Hydrodynamic Coupling Melts Acoustically Levitated Crystalline Rafts
Brady Wu, Bryan VanSaders, Melody X. Lim +1
The acoustic levitation of small particles provides a versatile platform to investigate the collective dynamical properties of self-assembled many-body systems in the presence of h…
Acoustically levitated lock and key grains
Melody X. Lim, Heinrich M. Jaeger
We present a scheme for generating shape-dependent, specific bonds between millimeter scale particles, using acoustic levitation. We levitate particles in an ultrasonic standing wa…
Mechanical properties of acoustically levitated granular rafts
Melody X. Lim, Bryan VanSaders, Anton Souslov +1
We investigate a model system for the rotational dynamics of inertial many-particle clustering, in which sub-millimeter objects are acoustically levitated in air. Driven by scatter…
Precision measurement of tribocharging in acoustically levitated sub-millimeter grains
Adam G. Kline, Melody Xuan Lim, Heinrich M. Jaeger
Contact electrification of dielectric grains forms the basis for a myriad of physical phenomena. However, even the basic aspects of collisional charging between grains are still un…
Edges control clustering in levitated granular matter
Melody Xuan Lim, Kieran A. Murphy, Heinrich M. Jaeger
The properties of small clusters depend dramatically on the interactions between their constituent particles. However, it remains challenging to design and tune the interactions be…
Cluster formation via sonic depletion forces in levitated granular matter
Melody X. Lim, Anton Souslov, Vincenzo Vitelli +1
The properties of small clusters can differ dramatically from the bulk phases of the same constituents. In equilibrium, cluster assembly has been recently explored, whereas out of…
Topology of Force Networks in Granular Media under Impact
Melody X. Lim, Robert P. Behringer
We investigate the evolution of the force network in experimental systems of two-dimensional granular materials under impact. We use the first Betti number, , and persistence…
Force and Mass Dynamics in Non-Newtonian Suspensions
Melody X. Lim, Jonathan Barés, Hu Zheng +1
Above a certain solid fraction, dense granular suspensions in water exhibit non-Newtonian behavior, including impact-activated solidification. Although it has been suggested that s…
