La luz que nos permite descubrir lo invisible

Light usually travels freely through space—but at a surface, everything changes. When light hits the boundary between two materials, it can become trapped, slow down, and merge with the atoms of the solid, forming invisible waves that live only at the surface. In this talk, we’ll explore how these hidden forms of light behave, how scientists have learned to see them, and why they are reshaping our understanding of materials, chemistry, and light itself.

Este verano tendremos la suerte de asistir a uno de los espectáculos más asombrosos que nos ofrece la naturaleza: un eclipse total de Sol. Pero… ¿sirven para algo los eclipses? Vamos a explorar los grandes descubrimientos científicos que han sido posibles gracias a los eclipses, viajando desde nuestro propio planeta hasta los mundos más remotos conocidos de nuestra galaxia.

Most objects we see occupy three dimensions of space, and for the longest time scientists thought that was all there was. This idea changed during this century, where hundreds of two-dimensional materials have been discovered and measured. Some materials have properties that are universal and see little change, others are magnetic, and others conduct better than others. It is, however, very hard to find a single material with several interesting properties. In this talk I will tell the story of topological materials and how we combine different materials to get the ideal mix.
