An effective magnetic field from optically driven phonons

Nature Physics volume 13, pages 132–136 (2017)Cite this article

Abstract

Light fields at terahertz and mid-infrared frequencies allow for the direct excitation of collective modes in condensed matter, which can be driven to large amplitudes. For example, excitation of the crystal lattice1,2 has been shown to stimulate insulator–metal transitions3,4 , melt magnetic order5,6 or enhance superconductivity7,8,9 . Here, we generalize these ideas and explore the simultaneous excitation of more than one lattice mode, which are driven with controlled relative phases. This nonlinear mode mixing drives rotations as well as displacements of the crystal-field atoms, mimicking the application of a magnetic field and resulting in the excitation of spin precession in the rare-earth orthoferrite ErFeO3. Coherent control of lattice rotations may become applicable to other interesting problems in materials research—for example, as a way to affect the topology of electronic phases.

Contributions

A.Cavalleri conceived the project together with T.F.N. T.F.N. and A.Cartella built the mid-infrared pump/Faraday-rotation probe experimental set-up with help from A.Cantaluppi and M.F. T.F.N. and A.Cartella performed the measurements. A.Cartella and T.F.N. developed the 1D-FDTD code and performed the simulations with help from R.V.M. (for the solution of the Landau–Lifshitz equation). T.F.N. analysed the experimental data. A.V.K., R.V.M. and D.B. identified the material system for the project and helped in the analysis of the data. R.M. collaborated in the interpretation of the data. The manuscript was written by T.F.N. and A.Cavalleri, with feedback from all co-authors.
