The quantum Rabi model describes the coupling of a two-state system to a bosonic field mode. Recent theoretical work has pointed out that a generalized periodic version of this model, which maps onto Hamiltonians applicable in superconducting qubit settings, can be quantum simulated with cold trapped atoms. Here, we experimentally demonstrate atomic dynamics predicted by the periodic quantum Rabi model far in the deep strong-coupling regime.

Abstract Inclusive production processes will be important for the first observations of XYZ states at new generation electron-hadron colliders, as they generally benefit from larger cross sections than their exclusive counterparts. We make predictions of semi-inclusive photoproduction of the χc1(1P) and X(3872), whose peripheral production is assumed to be dominated by vector exchanges.

Massive stars have relatively short lifetimes, typically lasting only a few million years. They eventually transform into compact remnants as black holes (BH) or neutron stars (NS), after departing from the main sequence (MS). These remnants possess significantly higher masses compared to their long-lived (> few Gyr), low-mass counterparts.

We present observations of the central 9 kpc of the Antennae merger (NGC 4038/9) at 55 pc resolution in the CO (2–1) line obtained with the Atacama Large Millimeter/submillimeter Array (ALMA). We use a pixel-based analysis to compare the gas properties in the Antennae to those in 70 nearby spiral galaxies from the PHANGS-ALMA survey, as well as the merger and nearest luminous infrared galaxy NGC 3256.

Bilateral symmetry is widespread across animals, yet, among bilaterians, many cases of conspicuous asymmetries evolved. This means that bilaterally homologous structures on the left and right side display divergent phenotypes. Evolution of such divergent phenotypes between otherwise similarly shaped structures can be thought to be favoured by modularity, but this has rarely been studied in the context of left-right differences.

Compact massive relic galaxies are a class of galaxies that exhibit characteristics suggesting they have remained largely unchanged since their initial formation, making them ‘relics’ of the early universe. These galaxies represent a distinct class characterized by strongly peaked high-velocity dispersion profiles with large rotational velocities.

The paper ‘The formation of early-type galaxies through monolithic collapse of gas clouds in Milgromian gravity’ was published by Eappen et al. (2022). We report the correct version of equation (8) on p. 1083. The error has no effect on the results or conclusions of the study as the correct equation was applied in the calculations, but could lead to mistakes if used incorrectly in future studies. The correct equation is© 2024 The Author(s).

We have used data from the Outer Galaxy High-Resolution Survey (OGHReS) to refine the velocities, distances, and physical properties of a large sample of 3 584 clumps detected in far infrared/submillimetre emission in the Hi-GAL survey located in the ℓ = 250○ − 280○ region of the Galactic plane. Using 12CO and 13CO spectra, we have determined reliable velocities to 3 412 clumps (95 per cent of the sample).
