Abstract. Understanding and controlling vibrations in condensed matter is emerging as an essential necessity both at fundamental level and for the development of a broad variety of technological applications. Intelligent design of the band structure and transport properties of phonons at the nanoscale and of their interactions with electrons and photons impact the efficiency of nanoelectronic systems and thermoelectric materials, permit the exploration of quantum phenomena with micro-and nanoscale resonators, and provide new tools for spectroscopy and imaging. In this colloquium we assess the state of the art of nanophononics, describing the recent achievements and the open challenges in nanoscale heat transport, coherent phonon generation and exploitation, and in nano-and optomechanics. We also underline the links among the diverse communities involved in the study of nanoscale phonons, pointing out the common goals and opportunities.

Displacemon Electromechanics: How to Detect Quantum Interference in a Nanomechanical Resonator

et al. 2018

We introduce the "displacemon" electromechanical architecture that comprises a vibrating nanobeam, e.g., a carbon nanotube, flux coupled to a superconducting qubit. This platform can achieve strong and even ultrastrong coupling, enabling a variety of quantum protocols. We use this system to describe a protocol for generating and measuring quantum interference between trajectories of a nanomechanical resonator. The scheme uses a sequence of qubit manipulations and measurements to cool the resonator, to apply two effective diffraction gratings, and then to measure the resulting interference pattern. We demonstrate the feasibility of generating a spatially distinct quantum superposition state of motion containing more than 10 6 nucleons using a vibrating nanotube acting as a junction in this new superconducting qubit configuration.

“…Cooling a mechanical oscillator to its quantum ground state is a prerequisite for observing quantum processes [8]. Several different kinds of systems, for example, nanomechanical systems [9][10][11], micromechanical systems [12,13], and suspended mirrors in Fabry-Pérot cavities [2,14] have been used for this purpose. For all mechanical systems, thermal noise is unavoidable unlike other noise sources that can be eliminated by using filters, screens, insulators, etc.…”

We propose a scheme in which the cooling of a mechanical resonator is achieved by exposing the optomechanical system to a non-Markovian environment. Because of the backflow from the non-Markovian environment, the phonon number can go beyond the conventional cooling limit in a Markovian environment. Utilizing the spectrum density obtained in the recent experiment [Nature Communications 6, 7606 (2015)], we show that the cooling process is highly effective in a nonMarkovian environment. The analysis of the cooling mechanism in a non-Markovian environment reveals that the non-Markovian memory effect is instrumental to the cooling process.
