Direct measurements of the extraordinary optical momentum and transverse spin-dependent force using a nano-cantilever
An unexpected optical momentum and force perpendicular to the wavevector are measured using a nano-cantilever in an evanescent optical field, confirming a 75-year-old prediction.

Chiral magnetic effect in ZrTe5
A magnetotransport study of zirconium pentatelluride now reveals evidence for a chiral magnetic effect, a striking macroscopic manifestation of the quantum and relativistic nature of Weyl semimetals.

Single-shot simulations of dynamic quantum many-body systems
A simulation method connects single-shot measurements in ultracold atom experiments to the probability distribution of the many-body wavefunction, elucidating the role of the fluctuations in different experimental situations.

Operational formulation of time reversal in quantum theory
A reformulation of quantum theory aims at reconciling transition probabilities with time reversal in connection to Wigner’s notion of symmetry, expanding the known classes of symmetry transformations.

Universal decoherence due to gravitational time dilation
Gravity and quantum mechanics are expected to meet at extreme energy scales, but time dilation could induce decoherence even at low energies affecting microscopic objects—a prospect that could be tested in future matter-wave experiments.

A quantum network of clocks
A proposed network of atomic clocks—using non-local entangled states—could achieve unprecedented stability and accuracy in time-keeping, as well as being secure against internal or external attack.

Isolate the subject
Can a photon be separated from its polarization; or an electron from its magnetic moment? Recent work suggests that in certain contexts, this might not be as impossible as it sounds.

Waiter, bring me ±ε!
Thermodynamic processes at the microscopic scale can be quite surprising. New limits on the amount of work that can be extracted from a system in an almost deterministic fashion have now been uncovered.
