THz-induced phonon mode mixing and collective dynamics in a polar nanolattice

Elizabeth Skoropata, Peter M. Derlet, Hiroki Ueda +13

Manipulating phonons through symmetry is a fundamental approach to alter the dynamic responses of materials. Most often new phases are sought through control of the unit-cell (e.g.…

Ultrafast Decoherence of Charge Density Waves in KMoO

Rafael T. Winkler, Larissa Boie, Yunpei Deng +20

Recent works have suggested that transient suppression of a charge density wave (CDW) by an ultra-short excitation can lead to an inversion of the CDW phase. We experimentally inve…

Optical excitation of electromagnons in hexaferrite

Hiroki Ueda, Hoyoung Jang, Sae Hwan Chun +11

Understanding ultrafast magnetization dynamics on the microscopic level is of strong current interest due to the potential for applications in information storage. In recent years,…

Ultrafast modulation of covalency in GeTe driven by a ferroelectric soft mode

Bulat Burganov, Vladimir Ovuka, Matteo Savoini +4

The general idea of using ultrashort light pulses to control ferroic order parameters has recently attracted attention as a means to achieve control over material properties on unp…

Spectrally-resolved dielectric function of amorphous and crystalline GeTe nanoparticle thin films

Ann-Katrin U. Michel, Marilyne Sousa, Maksym Yarema +5

Phase-change materials (PCMs), which are well-established in optical and random-access memories, are increasingly studied for emerging topics such as brain-inspired computing and a…
