Nanomechanics, nanoacoustics, and nanophononics refer to the engineering of acoustic
phonons and elastic waves at the nanoscale and their interactions with other excitations …

Cavity optomechanical coupling based on radiation pressure, photothermal forces and the
photoelastic effect has been investigated widely over the past few decades, including optical …

Bloch oscillations (BOs) were initially predicted for electrons in a solid lattice to which a static
electric field is applied. The observation of BOs in solids remains challenging due to the …

Phononic crystal (PnC) has attracted strong attention due to its tremendous capabilities to
manipulate acoustic and elastodynamic waves. For high frequency (gigahertz) PnC, the size …

Nanophononics is essential for the engineering of thermal transport in nanostructured
electronic devices, it greatly facilitates the manipulation of mechanical resonators in the …

It has long been known that quantum particles moving in a periodic lattice and subject to a
constant force field undergo an oscillatory motion that is referred to as Bloch oscillations …

We present a quantum theory for a fully coupled hybrid optomechanical system where all
mutual couplings between a two-level atom, a confined photon mode, and a mechanical …

The Su-Schrieffer-Heeger (SSH) model is likely the simplest one-dimensional concept to
study nontrivial topological phases and topological excitations. Originally developed to …

Inelastic scattering of light by acoustic phonons has potential for the tailored generation of
frequency combs, laser-line narrowing, and all-optical data storage. To be efficient, these …

Transient reflectivity traces measured for nanometer-sized films (6–40 nm) of the topological
insulator Bi 2 Se 3 revealed GHz-range oscillations driven within the relaxation of hot …
