Goya’s artwork imaging with Terahertz waves

Optics Express, 2013
In this paper we use a Terahertz (THz) time-domain system to image and analize the structure of an artwork attributed to Spanish artist Goya painted in 1771. The Thz images show features that cannot be seen in the optical or X-ray images that providence evidence of its authenticity, which is validated by other independent studies.

Laser‐Induced Ultrafast Magnetic Phase Transition in 2D Van Der Waals Antiferromagnetic Heterostructures

Advanced Science, EarlyView.
In this work, ultrafast laser‐induced spin transfer and spin relaxation dynamics in 2D van der Waals antiferromagnetic CrI3/CrGeTe3 heterostructures are investigated. Laser excitation is demonstrated to induce pronounced interlayer nonequilibrium spin dynamics and ultrafast magnetic moment reconstruction, driving a transition from an antiferromagnetic (
