High harmonics illuminate the movement of atoms and electrons

Laser light can radically change the properties of solid materials, making them superconducting or magnetic within millionths of a billionth of a second. The intense light causes fundamental, immediate changes in a solid ...

Following ultrafast magnetization dynamics in depth

The future development of functional magnetic devices based on ultrafast optical manipulation of spins requires an understanding of the depth-dependent spin dynamics across the interfaces of complex magnetic heterostructures. ...

Understanding room-temperature superconductivity

Room-temperature superconductors could transform everything from electrical grids to particle accelerators to computers, but researchers are still trying to understand how these materials function on the atomic level.

Investigating electrons with a traditional scanning microscope

Physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have designed a framework that allows scientists to observe interactions between light and electrons using a traditional scanning electron microscope. ...

Controlling the waveform of ultrashort infrared pulses

An international team of laser physicists of the attoworld team at LMU and the Max Planck Institute of Quantum Optics has achieved unprecedented control over light pulses in the mid-infrared wavelength range.
