A study led by Politecnico di Milano, recently published in Nature Photonics, highlights the crucial role of virtual charges in insulating materials.
One of the biggest challenges in modern physics and photonics is understanding how materials behave when struck by extremely brief flashes of light. A new study, published in Nature Photonics and led by researchers at Politecnico di Milano, uncovers a crucial factor that has often been overlooked: the role of virtual charges. These are charge carriers that exist only during their interaction with light, yet they have a significant impact on how a material responds.
