GdTbMnO oxides are characterized by two main competing states that exhibit both ferroelectric and multiferroic ordering. Both states involve cycloidal magnetic order that drives ferroelectricity. In their new article, a collaboration of researchers from Japan discovered that exposure of GdTbMnO to x-ray irradiation induces a reversible transition into a new hidden state, which is also characterized by cycloidal order, but with a different modulation wave vector. The ability to manipulate the state with x-rays suggests a novel route for photocontrol of multiferroic materials.

Magnetoelastic coupling describes the interaction between the magnetic degrees of freedom of a material and its strain. This Rapid Communication presents a microscopic model of magnetoelasticity in which all parameters are derived from first-principles calculations. In application to multiferroic materials, the model reveals a new contribution to the electric polarization that appears as a combination of the magnetoelastic and piezoelectric effects. Surprisingly, in the prototypical multiferroic material BiFeO the new effect is responsible for a significant share of the total polarization and exceeds the known ionic and electronic contributions.

Using a nonequilibrium dynamical mean-field theory the authors study relaxation of a hot-electron distribution coupled to optical phonons. Their main interest is in the adiabatic regime of phonon frequencies smaller than the electronic bandwidth and in an extended analysis of photoemission spectra. In this limit initial coherent phonon oscillations become strongly damped, leaving the system in a mixture of excited polaron states and metastable delocalized states.

Nonequilibrium dynamics of interacting quantum many-body physics has recently attracted great attention. The authors address here the nonequilibrium dynamics of a single electron interacting through a Holstein-like coupling with dispersionless phonons on a one dimensional lattice. Using diagonalization in a limited functional space, they identify two different regimes: (1) the relaxation regime where, during a characteristic time scale, a net energy is transferred between the electronic and the phononic subsystem; and (2) the stationary regime, characterized by zero energy transfer and by persisting coherent oscillations in the dynamics of observables.
