Phononic crystals (PnCs) control the transport of sound and heat similar to the control of
electric currents by semiconductors and metals or light by photonic crystals. Basic and …

The central concept in phononics is the tuning of the phonon dispersion relation, or phonon
engineering, which provides a means of controlling related properties such as group velocity …

We combine experimental, numerical, and analytical tools to design highly nonlinear
mechanical metamaterials that exhibit a new phenomenon: gaps in amplitude for elastic …

Phononic crystals (PnCs) are capable of manipulating the flow of elastic energy through
their periodic structures and have emerged as a promising field in the last two decades …

The hypersonic phonon propagation in large-area two-dimensional colloidal crystals is
probed by spontaneous micro Brillouin light scattering. The dispersion relation of thermally …

Microscale energy transport processes are crucial in microelectronics, energy-harvesting
devices, and emerging quantum materials. To study these processes, methods that can …

We demonstrate how to directly transform a close-packed hexagonal colloidal monolayer
into nonclose-packed particle arrays of any two-dimensional symmetry at the air/water …

Understanding contact mechanics and adhesion processes in thin films and micro-
structured materials is fundamental in phonon and heat transport phenomena and is …

The interaction of Rayleigh surface waves with a random arrangement of oscillators on the
surface of an elastic half-space is analyzed with the help of the surface elastodynamic …

The effect of elastic anisotropy on thermal diffusivity determination by transient grating
spectroscopy (TGS) was studied. In experiments performed on a set of cubic single crystals …
