    Ultrashort high-intensity laser pulses change the properties of dielectrics in different ways. One unexpected outcome is light amplification in an excited dielectric, observed in a two-colour pump–probe experiment.

    By engineering photosensitive proteins and tweaking the classical properties of light, it should be possible to tune the response of a cell equipped with photoreceptors. But would these cells be able to sense the subtle quantum properties of light?

    α-RuCl3 has recently attracted great interest as a possible experimental realization of the Kitaev model. Neutron scattering measurements of a single crystal of this material reveal signatures of Majorana excitations, consistent with Kitaev’s predictions.

    A thermodynamic study of doped single crystals of NbFe2 reveals the phase diagram of this system as a function of temperature, magnetic field and Nb doping — which includes an unusual quantum tricritical point.

    When molten tin droplets impact clean substrates, they either stick or spontaneously detach depending on the substrate temperature. Competition between heat extraction and fluidity controls this behaviour, foregoing the need for surface treatment.

    Particles in strongly coupled plasmas behave collectively as in liquids, with additional long-range collisions. Experimental evidence is provided that fluctuation theorems obeyed by liquid are also valid for strongly coupled dusty plasmas.

    Traditionally quantum state tomography is used to characterize a quantum state, but it becomes exponentially hard with the system size. An alternative technique, matrix product state tomography, is shown to work well in practical situations.

    A detailed resonant inelastic X-ray scattering (RIXS) study of a series of well-known cuprate superconductors reveals a correlation between the number of apical oxygens in these systems, and the strength of their in-plane exchange interaction.

    Magneto-optical trapping and sub-Doppler cooling of atoms has been instrumental for research in ultracold atomic physics. This regime has now been reached for a molecular species, CaF.
