Light-matter Interaction

Researchers from the MPSD and the University of Oxford manage to drive a prototypical antiferromagnet into a new magnetic state, using terahertz frequency light. Their groundbreaking method produces an effect orders of magnitude larger than previously achieved - on ultrafast time scales. more

Laser light with a broad colour spectrum turns the insulating quasi two-dimensional material La₂CuO₄ (LCO) into a three-dimensional metal. The research, now published in PNAS, reveals that specific vibrations of the crystal lattice are involved in this metallization process. more

Researchers from Hamburg and Bombay expose 2D monolayer of defective hexagonal boron nitride to an intense light flash to explore how defects influence the motion of electrons in solids during HHG. more
