Laser cooling underpins the field of ultracold quantum gases. This Review surveys recent methodological advances that are pushing quantum gases into new regimes.
Large arrays of atoms and molecules can be arranged and controlled with high precision using optical tweezers. This Review surveys the latest methodological advances and their applications to quantum technologies.
Active matter can have macroscopic properties that defy the usual laws of hydrodynamics. Now these tell-tale properties have been traced down to the non-equilibrium character and handedness of interactions between individual particles.
Precise measurements of the annihilation of an electron–positron pair into a neutron–antineutron pair allow us to take a look inside the neutron to better understand its complex structure.
Interacting quantum systems are difficult to formulate theoretically, but Nikolai Bogoliubov offered a workaround more than 70 years ago that has stood the test of time. Now, correlations that are a crucial feature of his theory have been observed.
It has long been assumed that the quantum statistics of light are preserved when photons interact with plasmons. An analysis of the scattering process shows that this is not always the case, as light can mix and match different plasmonic pathways.
Most systems exhibiting topological superconductivity are artificial structures that require precise engineering. Now, a layered material shows tantalizing signs of the phenomenon.
Molecular spin qubits that can be controlled electrically are typically susceptible to decoherence. Holmium molecular spins provide a solution by combining robust coherence with strong spin–electric coupling.
At high pressure and temperature, water forms two crystalline phases, known as hot ‘black’ ices due to their partial opaqueness. A detailed characterization of these phases may explain magnetic field formation in giant icy planets like Neptune.
Integrating quantum technology with existing telecom infrastructure is hampered by a mismatch in operating frequencies. An optomechanical resonator now offers a strain-mediated spin–photon interface for long-distance quantum networks.
In a study on high-harmonic generation from a dense atomic xenon gas, the strong-field light–matter interaction is shown to leave a quantum mechanical imprint on the incident light that escapes the semiclassical picture of strong-field physics.
The interaction between light and the crystal lattice of a quantum material can modify its properties. Utilizing nonlinear interactions allows this to be done in a controlled way to design specific non-equilibrium functionalities.
Network representations of complex systems are limited to pairwise interactions, but real-world systems often involve higher-order interactions. This Perspective looks at the new physics emerging from attempts to characterize these interactions.
The tin isotope 100Sn is key to understanding nuclear stability, but little is known about its properties. Precision measurements of closely related indium isotopes have now pinned down its mass.
Scanning tunnelling microscopy reveals an unexpected periodicity in the local density of states of a transition metal dichalcogenide — with a puzzling wavelength that casts the material as a quantum spin liquid.
