Quantum sensors based on atom interferometry are moving from fundamental research towards commercial applications in metrology, geophysics, space, civil engineering, oil and minerals exploration, and navigation, but a number of challenges need to be overcome.
The dynamics of quantum information is opening new perspectives on the behaviour of complex many-body systems. This Perspective covers progress made with atomic gases and trapped ions for accessing the dynamics of quantum correlations, entanglement and information scrambling in a broad parameter regime.
Electric dipole moments (EDMs) of atoms and molecules are a sensitive probe for sources of time-reversal symmetry violation beyond the standard model. In this Perspective, we review recent progress in EDM searches with atoms and molecules and survey proposed next-generation experiments.
Although the differential equations that describe the physical climate system are deterministic, there are reasons, both theoretical and practical, why computational representations of these equations should be stochastic. This Perspective surveys the benefits of stochastic modelling of weather and climate.
Atomically precise measurements in 2D materials can be used to quantify the effects of energetic electron irradiation. In this Perspective, we discuss how understanding of electron–matter interactions can help to stimulate the development of quantitative models that are generalizable to a wide range of materials.
This Perspective describes how statistical physics helps understand some of the key aspects of cities: their spatial structure and social organization, the distribution of their population, urban mobility and how some critical factors vary with population.
Synthetic dimensions provide a way to artificially engineer extra spatial dimensions through other degrees of freedom. We review how synthetic dimensions have emerged as a promising tool for quantum simulations of topological lattice models in atomic, molecular and optical systems.
An analysis of the number of physicists and their career paths reveals the changing landscape of the physics subdisciplines, highlighting the connections between different fields and the effects of large collaborations.
