How to make a material more correlated with light

Our preprint “Light-enhanced electron-phonon coupling from nonlinear electron-phonon coupling” is available on arXiv. In this work, it is shown how one can amplify electron-lattice coupling by using lasers that are tuned to a phonon, that is coupled quadratically to the electrons of the material. Such enhanced electron-lattice coupling can lead to the formation of polarons… Continue reading How to make a material more correlated with light

Control of competing orders

In a new theory published on arXiv today we show how a laser beam can exert control in a system with competing superconducting and charge orders. The underlying mechanism with a striking resonance for photon frequencies near the gap edge may even be used to understand light-induced superconductivity. The above figure illustrates how a symmetry… Continue reading Control of competing orders
