Radiation is a form of energy released in the form of rays, particles, or waves. It can be found all around us, from the sun and stars, to man-made sources like cell phones, computers, and nuclear power plants. Radiation can be both beneficial and harmful. It can be used to diagnose and treat illnesses and diseases, or it can cause long-term health problems such as cancer. On this page, you can find the latest news, articles, and videos about radiation and how it affects us.
We describe the achievement of a long-lived Floquet phase in graphene, where a non-equilibrium electronic population is stabilized by the interplay between coherent mid-infrared photoexcitation and incoherent phonon cooling.
A novel approach based on few-photon irradiation to achieve two-photon absorption (fpTPA) is proposed. For the first time, this enables the simultaneous realization of both high resolution and high efficiency in optical nanoprinting.
