Electrons dynamics control by shaping femtosecond laser pulses in micro/nanofabrication: modeling, method, measurement and application

During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...

Laser Light Rewrites Magnetism in Breakthrough Quantum Material

Scientists have demonstrated that light alone can reversibly control magnetism in a topological material. Researchers at the University of Basel and ETH Zurich have found a way to flip the magnetic ...
