Volume 5

The cover of this issue shows an illustration of a supersolid 4-droplet state in a cigar-shaped trap. See [Recati & Stringari]

The cover of this issue shows a foam-like structure in wood, an example of a disordered hierarchical structure in biology. See Zaiser & Zapperi

The cover of this issue illustrates the motion of trees in the wind. Understanding the physics of how structures respond to flows may enable measurements of wind conditions based on observations of natural environments. See Dabiri et al.

The cover of this issue illustrates the use of machine-learning-based sampling in lattice quantum chromodynamics simulations. See Cranmer et al.

The cover of this issue shows an artistic impression of topological Wannier cycles. See Lin et al.

The cover of this issue uses motifs from a Perspective on proliferating active matter. See Hallatschek et al.

The cover of this issue illustrates two open questions in the foundations of quantum mechanics: the quantum measurement problem and a quantum theory of gravity. See Cavalcanti et al.

The cover of this issue illustrates the use of graph neural networks at the Large Hadron Collider using a candidate Higgs boson decay event in the ATLAS detector. See DeZoort et al.

The cover of this issue depicts clouds, the physics of which depends on the physics of ice nucleation. See Knopf et al.

The cover of this issue illustrates the physics and sustainability theme launching this month. See Editorial

The cover of this issue uses charge density images of semiconductors, taken with differential phase contrast scanning transmission electron microscopy. See Addiego et al.

The cover of this issue is inspired by spatiotemporal intermittency near the onset of turbulence. See Hof
