Recent experimental developments in diverse areas—ranging from cold atomic gases to
light-driven semiconductors to microcavity arrays—move systems into the focus which are …

Fifty Years of the Dynamical Casimir Effect Next Article in Journal / Special Issue History and
Some Aspects of the Lamb Shift Previous Article in Journal Saga of Superfluid Solids Previous …

In most cosmological models, rapid expansion of space marks the first moments of the
Universe and leads to the amplification of quantum fluctuations. The description of …

Wave control is usually performed by spatially engineering the properties of a medium.
Because time and space play similar roles in wave propagation, manipulating time …

We study the dynamics of a supersonically expanding, ring-shaped Bose-Einstein
condensate both experimentally and theoretically. The expansion redshifts long-wavelength …

The Unruh effect predicts a thermal response for an accelerated detector moving through the
vacuum. Here we propose an interferometric scheme to observe an analogue of the circular …

The macroscopic characteristics of a material are determined by its elementary excitations,
which dictate the response of the system to external stimuli. The spectrum of excitations is …

Discussion Meeting on The next generation of analogue gravity experiments held at the
Royal Society in December 2019. This theme issue comprises a collection of recent …

The rapid expansion of the early universe resulted in the spontaneous production of
cosmological particles from vacuum fluctuations, some of which are observable today in the …

Predicting the dynamics of many-body systems far from equilibrium is a challenging
theoretical problem. A long-predicted phenomenon in hydrodynamic nonequilibrium …
