Book Description
The nonclassical behavior of mechanical objects is of both fundamental interest and potential technological utility. Mechanical resonators can be combined with superconducting microwave circuits to realize quantum technologies, acting as memories for computation and on-chip delay lines, with small footprints and large achievable coupling rates. The nonlinearity of the circuit enables quantum control of the mechanical mode, as well as nondemolition readout of the prepared mechanical states. This hybrid platform has seen great progress in recent years as both a flourishing technological avenue and as a platform to explore quantum behavior of mechanical motion. In this work, we describe a series of experiments which explore the versatile uses of a quantum acoustics platform built from piezoelectric nanomechanical resonators. First, we describe the design and experimental realization of a Purcell filter composed of lithium niobate Lamb-wave resonators. Next, we combine a superconducting transmon qubit with two phononic crystal resonators, also made of lithium niobate. We demonstrate full quantum control of the mechanical modes and perform quantum state tomography to extract the density matrices of the prepared states. In this effort, we also prepare and characterize a mechanical Bell-state between the two resonators, demonstrating a small-scale quantum acoustic processor. Last, using the same device, we use the qubit to perform phonon number-resolved detection of dissipation and dephasing of coherent states in the mechanical oscillator. We develop a model showing that the dissipation signatures are consistent with emission into a small ensemble of long-lived two-level system defects, thus elucidating the need for further refinement of fabrication techniques. Altogether, this dissertation represents an exploration of a wide range of different applications for a hybrid quantum acoustic platform.

Book Description
Phononic crystals are artificial periodic structures that can alter efficiently the flow of sound, acoustic waves, or elastic waves. They were introduced about twenty years ago and have gained increasing interest since then, both because of their amazing physical properties and because of their potential applications. The topic of phononic crystals stands as the cross-road of physics (condensed matter physics, wave propagation in inhomogeneous and periodic media) and engineering (acoustics, ultrasonics, mechanical engineering, electrical engineering). Phononic crystals cover a wide range of scales, from meter-size periodic structures for sound in air to nanometer-size structures for information processing or thermal phonon control in integrated circuits. Phononic crystals have a definite relation with the topic of photonic crystals in optics. The marriage of phononic and photonic crystals also provides a promising structural basis for enhanced sound and light interaction. As the topic is getting popular, it is nowadays presented and discussed at various international conferences. After the first ten years during which the topic has remained mainly theoretical with a few proof-of-concept demonstrations in the literature, the evolution has been towards applications, instrumentation, and novel designs. The physical explanations for various effects are now well understood and efficient numerical methods and analysis tools have been developed. The book contains a comprehensive set of finite element model (FEM) scripts for solving basic phononic crystal problems. The scripts are short, easy to read, and efficient, allowing the reader to generate for him(her)self band structures for 2D and 3D phononic crystals, to compute Bloch waves, waveguide and cavity modes, and more.

Book Description
This comprehensive book presents all aspects of acoustic metamaterials and phononic crystals. The emphasis is on acoustic wave propagation phenomena at interfaces such as refraction, especially unusual refractive properties and negative refraction. A thorough discussion of the mechanisms leading to such refractive phenomena includes local resonances in metamaterials and scattering in phononic crystals.

Book Description
Phononics: Interface Transmission Tutorial Book Series provides an investigation of modern systems that includes a discrete matrix description. Classical continuous systems relying on the use of differential equations are recalled, showing that they generally have a specific limit on their corresponding modern matrix formulation. A detailed description of the mathematical languages that enables readers to find the composite system linear transmission properties is provided in the appendix. The physical model is described with exacting detail, and the bibliography is built to cite—in chronological order—all the scientists that have contributed over many years. Each volume is written with the aim of providing an up-to-date and concise summary of the present knowledge of interface transmission science, thus fostering the exchange of ideas among scientists interested in different aspects of interface transmission. The book serves as an introduction to advanced graduate students, researchers, and scientists with little study on the subject, and is also useful to help keep specialists informed on general progress in the field. Offers a unique approach on phononics from the interfacial transmission point-of-view Teaches the modern physics of interface transmission, in particular, phononics through composite systems Authored and edited by world-leading experts on interface transmission

Book Description
During the last few years cavity-optomechanics has emerged as a new field of research. This highly interdisciplinary field studies the interaction between micro and nano mechanical systems and light. Possible applications range from novel high-bandwidth mechanical sensing devices through the generation of squeezed optical or mechanical states to even tests of quantum theory itself. This is one of the first books in this relatively young field. It is aimed at scientists, engineers and students who want to obtain a concise introduction to the state of the art in the field of cavity optomechanics. It is valuable to researchers in nano science, quantum optics, quantum information, gravitational wave detection and other cutting edge fields. Possible applications include biological sensing, frequency comb applications, silicon photonics etc. The technical content will be accessible to those who have familiarity with basic undergraduate physics.
