Computer-generated random phase two-dimensional profile imprinted on the boundary of a multimode laser cavity. Selected for an Editors’ Suggestion.

Dark matter accounts for roughly 85% of the matter in the Universe, yet its constituents remain unknown. Solving this mystery calls for a wide range of experiments that can detect dark matter constituents with different masses and interactions. Now, Gadi Afek at Yale University and colleagues have proposed a laboratory-based detector that is drastically different from existing experiments.

Some non-Hermitian skin modes can reconstruct themselves after scattering off an obstacle.

A persistent current can develop in a system of interacting fermions trapped in a ring geometry at low temperatures.

Simulations elucidate the crucial role of dynamic association and dissociation of surface ionization groups on the spontaneous self-organization of zwitterionic particles, which have oppositely charged patches.

The number of lasing modes increases as the characteristic scale of random phase fluctuation decreases in a degenerate cavity, providing a tunable platform for investigating many-body phenomena.

New measurements of the beam-normal single spin asymmetry in two calcium isotopes show clear differentiation between nuclei with Z$<$20 and recent results on lead nuclei.

The one- and two-electron valley state energies in silicon quantum dots are measured as the quantum dot potential is modified, demonstrating a new probe of the quantum well interface.

A new animal-foraging model accurately predicts the dynamics of Egyptian fruit bats, allowing researchers to uncover a surprising phase transition in the penchant of animals to explore.

The first observation of intermolecular Coulombic decay following inner-valence ionization in liquid water is made in a tabletop experiment.

The propensity rule for the total spin conservation of many-body ultracold collisions is confirmed experimentally.
