Quantum Hall systems represent an example of topological quantum matter, where quasiparticles with fractional statistics (anyons) may emerge. This Technical Review presents a survey of recent developments in quantum Hall interferometry.
Making a good review article is a team effort, involving authors, editors and referees. In honour of Peer Review Week, happening this month, we spotlight the essential role of peer reviewers.
More than 40 years ago the first Bell tests translated a purely philosophical conundrum to a physical experiment. In doing so, they changed our understanding of quantum mechanics and contributed to the development of quantum technologies.
The recent measurement of a nonlinear Hall effect has provided a new way to probe the spectral, symmetry and topological properties of quantum materials. This Perspective discusses the open questions around this new effect and potential applications.
Scientists studying cultural heritage use a variety of physics techniques to understand how pieces were made, their history and how to best preserve them. Six scientists who use different techniques describe their work — and how working with cultural heritage can lead to physics developments, too.
Blending occurs when multiple sources of light occupy the same region of the sky. This Perspective discusses the problems arising from blending for astrophysical and cosmological studies, and introduces the two main strategies for solutions.
The advent of commercial quantum devices has ushered in the era of near-term quantum computing. Variational quantum algorithms are promising candidates to make use of these devices for achieving a practical quantum advantage over classical computers.
A collaboration between art and science shows how to overcome the limits of traditional weaving techniques as reported in a recent article in Physical Review Letters.
Extremely stable laser sources are essential for high-precision experiments, such as interferometric gravitational wave detectors. Marina Trad Nery explains how to use radiation pressure to measure and stabilize power fluctuations in a laser beam.
Since the launch of arXiv 30 years ago, modes of information spread in society have changed dramatically — and not always for the better. Paul Ginsparg, who founded arXiv, discusses how academic experience with online preprints can still inform information sharing more generally.
Gaussian process regression (GPR) is a powerful, non-parametric and robust technique for uncertainty quantification and function approximation that can be applied to optimal and autonomous data acquisition. This Review introduces the basics of GPR and discusses several use cases from different fields.
As new events such as surfing, skateboarding, sport climbing and karate are added to the programme of the Tokyo Summer Olympics, we ponder how physics can help enhance athletic performance in elite sport.
