ON THE COVER

Fluorescence microscope image from a video showing the dynamics of active nematics confined to a cardioid along with the tracks of three defects, which form a braid. Selected for an Editors’ Suggestion.
Fereshteh L. Memarian et al.
Phys. Rev. Lett. 132, 228301 (2024)
EDITORS' SUGGESTION
Interatomic Coulombic decay is experimentally observed in a doubly excited atom despite its extremely short lifetime.
B. Bastian et al.
Phys. Rev. Lett. 132, 233001 (2024)
EDITORS' SUGGESTION
In a system where a standard antiferromagnet coexists with a second, ordered phase, which breaks the sublattice rotational symmetry spontaneously, altermagnetism may emerge as an electronic instability.

Phys. Rev. Lett. 132, 236701 (2024)
EDITORS' SUGGESTION
A mechanism for strong-coupling superconductivity based on the electron-phonon interaction, quadratic in phonon displacements suggests a new route to high-temperature superconductivity.
Zhaoyu Han, Steven A. Kivelson, and Pavel A. Volkov
Phys. Rev. Lett. 132, 226001 (2024)
EDITORS' SUGGESTION
Polarization-gated attoclock technique allows the observation of electron-electron interaction in nonsequential photoionization events.
YanLan Wang et al.
Phys. Rev. Lett. 132, 223202 (2024)
EDITORS' SUGGESTION
Observation of a heavy Fermi surface of charge-neutral spinons in BaNbRuO provides experimental evidence for a robust quantum spin liquid that features an extraordinarily large entropy and a linear heat capacity extending into the milli-Kelvin regime.
Hengdi Zhao et al.
Phys. Rev. Lett. 132, 226503 (2024)
EDITORS' SUGGESTION
Confining active nematics in cardioid-shaped wells leads to realization of the golden braid, a maximally efficient mixing state of exactly three defects with no defect creation or annihilation.

EDITORS' SUGGESTION
The newly constructed pseudomagic ensembles possess low nonstabilizerness but are computationally indistinguishable from those with high nonstabilizerness, having implications for quantum scramblers, quantum cryptography, and magic state distillation.
