Even by shining classical light on a single opening, one can perform a double-slit experiment and discover a surprising variety of quantum mechanical multi-photon correlations — thanks to surface plasmon polaritons and photon-number-resolving detectors.
Two adjacent layers flowing at different velocities in the same fluid are subject to flow instabilities. This phenomenon is now studied in atomic superfluids, revealing that quantized vortices act as both sources and probes of the unstable flow.
Interactions of atmospheric neutrinos with quantum-gravity-induced fluctuations of the metric of spacetime would lead to decoherence. The IceCube Collaboration constrains such interactions with atmospheric neutrinos.
Experiments probing three-dimensional crack propagation show that the critical strain energy needed to drive a crack is directly proportional to its geodesic length. This insight is a step towards a fully three-dimensional theory of crack propagation.
Stable regions in four-dimensional phase space have been observed by following the motion of accelerated proton beams subject to nonlinear forces. This provides insights into the physics of dynamical systems and may lead to improved accelerator designs.
Nonlinear resonances can cause particle loss in accelerators. Experiments confirm that a coupled nonlinear resonance traps beam particles on a four-dimensional closed curve. This finding allows the development of mitigation strategies.
A mechanism for the phase transition of charge density wave states via the generation and proliferation of topological defects with opposite phase windings is demonstrated in a heavy-fermion superconductor.
Exploring and exploiting electric dipole arrangements analogously to what is possible with magnetic spin textures is an emerging prospect. Now a spontaneous toroidal polar topology is observed in ferroelectric liquid crystals.
Computing is central to the enterprise of physics but few undergraduate physics courses include it in their curricula. Here we discuss why and how to integrate computing into physics education.
Injustices and oppression are pervasive in society, including education. An intersectional, equity-oriented approach can help remove systemic obstacles and improve the experience of marginalized people in physics education through decolonial and critical race lenses.
Increasingly, physics graduates take jobs outside academia. Active teaching approaches lead to deeper conceptual understanding and a more varied skill set and are therefore more likely to prepare students for successful careers.
Encouraging students to take ownership of their learning can improve their outcomes. This Perspective discusses ways to achieve this in the context of physics education and how digital technology can help Gen Z students in particular.
Women and ethnic and racial minority students are underrepresented in physics. This Review summarizes research on equity and inclusion in physics education and makes recommendations for making physics learning environments more equitable.
The local electronic structure of interface states between topologically distinct domains is imaged and controlled, allowing visualization of the interplay between strong interactions and non-trivial topology.
Copper-based and iron-based compounds exhibit an interplay between magnetism and superconductivity. Now, this idea is extended to two-dimensional oxide heterostructures, where a spatially varying superconducting order is demonstrated at the EuO/KTaO3 interface.
