The tuneable and nonlinear nature of the interactions between two optically levitated nanoparticles allows the observation of the system’s non-Hermitian dynamics and a mechanical lasing transition.

Non-reciprocal interactions between two optically levitated nanoparticles allow the observation of non-Hermitian dynamics and a mechanical lasing transition, and suggest applications in optomechanical sensing.

Error mitigation has helped improve the performance of current quantum computing devices. Now, a mathematical analysis of the technique suggests its benefits may not extend to larger systems.

Current muon beams have a phase-space volume that is too large for applications in muon colliders. Now, the reduction in the beam’s transverse emittance when passed through different absorbers in ionization cooling experiments is quantified.

The observation of phase modes of charge density wave has been a long-standing challenge. Such low-energy phase excitations have now been seen in a transition metal dichalcogenide.

The superconducting proximity effect has not been experimentally demonstrated in a quantum anomalous Hall insulator. Now this effect is observed in the chiral edge state of a ferromagnetic topological insulator.

This year marks the hundredth anniversary of Satyendra Nath Bose’s paper that stimulated the study of quantum statistics. We take this opportunity to celebrate the physics of bosons.

High harmonic generation has long been successfully described using the semi-classical three-step model. However, recent progress has introduced a quantum optical formulation, exposing the limitations of the semi-classical picture.

It has many names and yet no name. The designation of the universal gas constant as R has remained a mystery, as Karen Mudryk recounts.

Construction of the European Spallation Source began 10 years ago. Upon completion, its advanced technology and sustainable design will herald a new era for neutron scattering experiments.
