Beyond Smoke and Mirrors: “Magic Cavity” in Superconducting Quantum Circuits

In 1946, Edward M. Purcell proposed that the way an atom emits radiation is not the sole property of the atom itself, but rather can be strongly modified by the electromagnetic environment the atom is placed within.  Purcell’s particular interest was in how the intrinsic magnetic moment (spin) of atomic nuclei in solids and liquids [...]

Dimensional crossover in a layered ferromagnet detected by spin correlation driven distortions – new paper by the Hsieh group

Magneto-elastic distortions are commonly detected across magnetic long-range ordering (LRO) transitions. In principle, they are also induced by the magnetic short-range ordering (SRO) that precedes a LRO transition, which contains information about short-range correlations and energetics that are essential for understanding how LRO is established. However these distortions are difficult to resolve because the associated [...]

Endres & Painter groups collaborate on Telecom-Band Quantum Optics with Ytterbium Atoms and Silicon Nanophotonics

This new publication by members of the Endres and Painter groups is an Editors’ Suggestion in Physical Review, Applied. Wavelengths in the telecommunication window (ca.1.25–1.65 μm) are ideal for quantum communication, due to the low transmission loss in optical-fiber networks. To realize quantum networks operating at these wavelengths, we need long-lived quantum memories that couple efficiently [...]

Recent Paper by Endres group: Alkaline-Earth Atoms in Optical Tweezers

Cold atoms trapped in optical tweezers have become a powerful tool for quantum science. However, well-developed trapping techniques have so far been restricted to alkali atoms, which have just a single valence electron. Applying tweezer techniques to the two-valence-electron alkaline-earth atoms, which are used in the most precise atomic clocks, would enable many new experiments [...]

New paper by Motrunich group on OTOCs

A new paper by the Motrunich group studies out-of-time-ordered correlators (OTOCs) in hard-core boson models with short-range and long-range hopping and compares the results to the OTOCs in the Luttinger-liquid model. FIG. 2. from the paper - The overall picture of CXX(, t) calculated in (a) model Iand (b) model II, with L = [...]
