The world’s fastest electron microscope captures electron motion at a temporal resolution of one attosecond, enabling scientists to observe electron behavior with unprecedented precision.

The ultrafast dynamics and interactions of electrons in molecules and solids have long remained hidden from direct observation. For some time now, it has been possible to study these quantum-physical ...

Researchers have simplified a highly complex quantum imaging technique, 2DES, used to observe ultrafast electron interactions ...

Researchers at the University of Arizona have created the world’s fastest electron microscope, a remarkable device capable of capturing freeze-frame images of moving electrons. They anticipate ...

For the first time, scientists have experimentally confirmed that electrons can form tornado-like structures in momentum ...

At the heart of the new process are two pairs of so-called delay quarter wave plates. The design makes it possible to adjust the delay between two ultra-short laser pulses with a high degree of ...

Electrons oscillate around the nucleus of an atom on extremely short timescales, typically completing a cycle in just a few hundred attoseconds (one attosecond is a quintillionth of a second).

For the first time, researchers at the University of Nottingham’s School of Chemistry filmed the real-time growth and ...

Momentum space vs. position space Momentum space is a fundamental concept in physics that describes electron motion in terms of energy and direction, rather than their exact physical position.

Momentum space is a fundamental concept in physics that describes electron motion in terms of energy and direction, rather than their exact physical position. Position space (its "counterpart") is the ...

Researchers have experimentally demonstrated a quantum tornado. Electrons form vortices in the momentum space of the quantum semi-metal tantalum arsenide. A team of researchers from Würzburg has ...
