Advanced photonic nanostructures are currently revolutionizing the optics and photonics
that underpin applications ranging from light technology to quantum-information processing …

On-chip nanophotonic devices are a class of devices capable of controlling light on a chip to
realize performance advantages over ordinary building blocks of integrated photonics …

We propose how to create and manipulate one-way nonclassical light via photon blockade
in rotating nonlinear devices. We refer to this effect as nonreciprocal photon blockade (PB) …

We demonstrate that nanoparticle self-assembly can reach the same level of hierarchy,
complexity, and accuracy as biomolecules. The precise assembly structures of gold …

Integrated nonreciprocal optical components, which have an inherent asymmetry between
their forward and backward propagation direction, are key for routing signals in photonic …

Optical whispering gallery modes (WGMs) derive their name from a famous acoustic
phenomenon of guiding a wave by a curved boundary observed nearly a century ago. This …

Photon blockade is a dynamical quantum-nonlinear effect in driven systems with an
anharmonic energy ladder. For a single atom strongly coupled to an optical cavity, we show …

We experimentally demonstrate strong coupling between a one-dimensional (1D) single-
atom array and a high-finesse miniature cavity. The atom array is obtained by loading single …

Here we review the field of atom chips in the context of Bose–Einstein Condensates (BEC)
as well as cold matter in general. Twenty years after the first realization of the BEC and 15 …

Unlike optical waves, acoustic waves in fluids are described by scalar pressure fields, and
therefore are considered spinless. Here, we demonstrate experimentally the existence of …
