Natural and human environments are abundant of unused renewable energy such as
mechanical energy, acoustic energy, electromagnetic energy, thermal energy, etc. The idea …

Optical trap** has become a powerful tool in numerous fields such as biology, physics,
chemistry, etc. In conventional optical trap** systems, trap** and imaging share the …

Acoustic waves in a linear time-invariant medium are generally reciprocal; however,
reciprocity can break down in a time-variant system. In this Letter, we report on an …

Non-equilibrium assemblies, where units are able to harness available energy to perform
tasks, can often self-organize into dynamic materials that uniquely blend structure with …

One of the challenges for metasurface research is upscaling. The conventional methods for
fabrication of metasurfaces, such as electron-beam or focused ion beam lithography, are not …

Nanoelectromechanical systems (NEMS) that operate in the megahertz (MHz) regime allow
energy transducibility between different physical domains. For example, they convert optical …

Self-organization in nonequilibrium systems has been known for over 50 years. Under
nonequilibrium conditions, the state of a system can become unstable and a transition to an …

Disordered hyperuniform structures are locally random while uniform like crystals at large
length scales. Recently, an exotic hyperuniform fluid state was found in several …

Light and sound waves can move objects through the transfer of linear or angular
momentum, which has led to the development of optical and acoustic tweezers, with …

In this work, a one-dimensional porous silicon carbide phononic crystal (1D-PSiC PnC)
sandwiched between two rubber layers is introduced to obtain low frequency band gaps for …
