Specific heat measurements show the existence of a crossover between the superconducting pairing state (Bardeen-Cooper-Schrieffer) and a lower temperature superfluid condensate state (Bose-Einstein Condensate) in high-temperature cuprate superconductors.

World-leading constraints are placed on nonstandard neutrino interactions using eight years of TeV-scale atmospheric muon neutrino data.

A fluxonium processor with fast-frequency tunability and individual controls implements high-fidelity single-qubit and two-qubits gates.

High-resolution spectra of electron loss in CO${}_2$ reveal non-Born–Oppenheimer dynamics in the nuclear motion produced by vibrational coupling.

Predictions indicate that when a neutron star radiates a burst of radio waves, interactions of the burst with the star’s magnetic field should produce observable x rays.
