AbstractDisplacive martensitic phase transition is potentially promising in semiconductor-based data storage applications with fast switching speed. In addition to traditional phase transition materials, the recently discovered two-dimensional ferroic materials are receiving a lot of attention owing to their fast ferroic switching dynamics, which could tremendously boost data storage density and enhance read/write speed. In this study, we propose that a terahertz laser with an intermediate intensity and selected frequency can trigger ferroic order switching in two-dimensional multiferroics, which is a damage-free noncontacting approach. Through first-principles calculations, we theoretically and computationally investigate optically induced electronic, phononic, and mechanical responses of two experimentally fabricated multiferroic (with both ferroelastic and ferroelectric) materials, β-GeSe and α-SnTe monolayer. We show that the relative stability of different orientation variants can be effectively manipulated via the polarization direction of the terahertz laser, which is selectively and strongly coupled with the transverse optical phonon modes. The transition from one orientation variant to another can be barrierless, indicating ultrafast transition kinetics and the conventional nucleation-growth phase transition process can be avoidable.

The electrodynamic response in the normal and superconducting ground states of K 3 C 60 and Rb 3 C 60 is reviewed. The normal state optical properties are rather unconventional since they can be explained only by considering the interplay of a Drude-like and a mid-infrared absorption component. On the other hand, the superconducting state optical properties are more straightforward since they display clear fingerprints related to the conventional weak coupling limit of the BCS ground state. Our optical spectra clearly display a well developed excitation due to the superconducting gap. Moreover, the analysis of our optical results in the superconducting state within the standard Eliashberg electron–phonon theory of superconductivity strongly supports a pairing mechanism mediated by high frequency intramolecular phonon modes.
