A tell-tale wiggle
Nature Physics, Published online: 19 August 2021; doi:10.1038/s41567-021-01342-9
Scanning tunnelling microscopy reveals an unexpected periodicity in the local density of states of a transition metal dichalcogenide — with a puzzling wavelength that casts the material as a quantum spin liquid.

Evidence for quantum spin liquid behaviour in single-layer 1T-TaSe<sub>2</sub> from scanning tunnelling microscopy
Nature Physics, Published online: 19 August 2021; doi:10.1038/s41567-021-01321-0
Some quantum spin liquids are expected to have an effective Fermi surface of fractionalized spinon excitations. The two-dimensional spin liquid candidate 1T-TaSe2 has charge density modulations that may be caused by an unstable spinon Fermi surface.

Generation of optical Schrödinger cat states in intense laser–matter interactions
Nature Physics, Published online: 19 August 2021; doi:10.1038/s41567-021-01317-w
Schrödinger cat states are observed in intense laser–atom interactions. These are a superposition of the initial state of the laser and the coherent state that results from the interaction between the light and atoms.

Laboratory evidence for proton energization by collisionless shock surfing
Nature Physics, Published online: 19 August 2021; doi:10.1038/s41567-021-01325-w
Proton acceleration by a super-critical collisionless shock is observed in laboratory experiments, and numerical simulations suggest shock surfing as the underlying acceleration mechanism.
