Engineering classical waves with quantized energy spectra in periodic media
Arnaud Lazarus, Georgi Gary Rozenman, John W. M. Bush
Field quantization is a central feature of modern physics, that underpins the concept of photons and forms the foundation of quantum electrodynamics as well as much of solid-state…
Thermodynamics of bouncing grains
Olivier Devauchelle, Predrag PopoviÄ, Predrag Popović +4
When a horizontal plate vibrates strongly enough, it causes small particles such as sand grains to continually bounce on it and, over time, to diffuse across its surface. This phen…
A granular Büttiker-Landauer motor
Olivier Devauchelle, Predrag PopoviÄ, Predrag Popović +4
Random walkers usually diffuse according to Fick's law. On average, they move down the gradient of their concentration and, in the absence of external force, tend to distribute the…
Observation of the Aharonov-Bohm Effect in Pilot-Wave Hydrodynamics
Georgi Gary Rozenman, Kyle I. McKee, Arnaud Lazarus +2
We report the results of an experimental study of an analog of the Aharonov-Bohm (AB) effect achieved with the hydrodynamic pilot-wave system. A walking droplet is confined to an a…
Harnessing Oscillatory Dynamics for Reprogrammable Mechanical Functionality
Sophie Monnery, Giada Risso, Loucas Plado Costante +2
A long-standing goal in the field of "mechanical computing" is the creation of truly reprogrammable mechanical structures, where the function of each unit can be dynamically define…
Wave-number lock-in in buckled elastic structures: an analogue to parametric instabilities
Helen E. Read, Giada Risso, Adel Djellouli +2
Parametric instabilities are a known feature of periodically driven dynamic systems; at particular frequencies and amplitudes of the driving modulation, the system's quasi-periodic…
