Periodically driving strongly correlated systems offers new opportunities to control their properties. Heating effects, however, often hinder the actual realization of interesting states. Here, the authors study a model of a Mott insulator with a time-periodic Hubbard on-site potential coupled to a dissipative reservoir. Tuning the frequency above a characteristic value, they unveil a regime where the creation of doublon-holon excitations is greatly enhanced with respect to equilibrium. Below a certain effective temperature, this far-from-equilibrium state would give rise to the exotic -pairing superconduting state.

A topological insulator can be converted to an axion insulator when time reversal symmetry is broken, which leads to the opening of a gap in the Dirac surface state. Recently, MnBiTe was predicted to host such a state upon antiferromagnetic ordering. Collecting and analyzing very detailed photoemission data, the authors demonstrate that this does not occur and that the Dirac surface state remains gapless well below the Néel temperature. Most likely, this is due to the complexity of the magnetic ordering at the surface. The quest for the discovery of an axion insulator is, therefore, still on.

Distorting a crystal affects its magnetic properties; vice versa, magnetic interactions can influence the lattice and its vibrations. By probing optical phonons – quantized sound waves excited by infrared radiation – we identify changes in the crystal symmetry related to the magnetic ground state of the widely studied quantum spin liquid candidate herbertsmithite. We determine the atomic motion of all 54 phonon modes and specify a possible symmetry breaking associated with the slowest phonons, providing insight into the coupling of magnetic and structural properties.
