3D light fields push electrons into quantum states previously beyond experimental reach
Physicists at the University of Oldenburg have developed a method to generate 3D light fields using superimposed laser pulses. This technique allows researchers to manipulate electrons into previously inaccessible quantum states, expanding the toolkit for experimental optics.
Why it matters
This advancement in quantum physics could lead to better control over light-matter interactions and new methods for identifying chiral structures.

Add as preferred source Using an interferometer, the researchers split laser light into two beams of different colours. They then superimposed these in a vacuum chamber to create 3D light fields, which they used to manipulate electrons.

Using the same method, they were also able to excite electrons into quantum states that had previously been inaccessible in experiments.
