Topological acoustics is an emerging field that lies at the intersection of condensed matter
physics, mechanical structural design and acoustics engineering. It explores the design and …

Cavity magnonics deals with the interaction of magnons—elementary excitations in
magnetic materials—and confined electromagnetic fields. We introduce the basic physics …

According to quantum mechanics, a physical system can be in any linear superposition of its
possible states. Although the validity of this principle is routinely validated for microscopic …

The quest for realizing and manipulating ever smaller man-made movable structures and
dynamical machines has spurred tremendous endeavors, led to important discoveries, and …

Conversion of electrical and optical signals lies at the foundation of the global internet. Such
converters are used to extend the reach of long-haul fibre-optic communication systems and …

Nanomechanics has brought mesoscopic physics into the world of vibrations. Because
nanomechanical systems are small, fluctuations are significant, the vibrations already …

Full manipulation of a quantum system requires controlled evolution generated by nonlinear
interactions, which is coherent when the rate of nonlinearity is large compared with the rate …

The recent development of hybrid systems based on superconducting circuits provides the
possibility of engineering quantum sensors that exploit different degrees of freedom …

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

Entanglement, an essential feature of quantum theory that allows for inseparable quantum
correlations to be shared between distant parties, is a crucial resource for quantum …
