Physical Review X (PRX) is APS's newest, online-only, and fully open access journal. Its broad scope encompasses all areas of pure, applied, and interdisciplinary physics. PRX carefully applies highly selective editorial standards comparable to those of the top journals in physics and aims to attract, select, and publish papers that are exceptional in originality, substance, and significance. With its open access model and through innovation in content delivery, PRX disseminates important new results, both broadly and effectively, across the global science and engineering community.

Coupling qubits to sound in a multimode cavity

In a recent study, researchers at the University of Colorado have resolved phonon Fock states in the spectrum of a superconducting qubit coupled to a multimode acoustic cavity. Fock states (or number states) are quantum states ...

Chiral zero sound found in Weyl semimetals

A pair of researchers at the Hong Kong University of Science and Technology has found that a chiral zero sound (CZS) effect can be induced in Weyl semimetals. In their paper published in the journal Physical Review Letters, ...
