High-order harmonic generation (HHG) provides a main route to generate attosecond (10-18 s) pulses, which have been considered “the world’s fastest film camera” for imaging the movement of electrons.

Scientists have found a rare quantum material in which electrons move in coordinated ways, essentially 'dancing.' Straining the material creates an electronic band structure that sets the stage for ...

The cellular method has been applied to the determination of electronic wave functions of the Bloch type in PbS. In each cell ψ is expanded in terms of 'Kubic harmonics', and a table of these ...

A research team found a way to measure the quantum distance of Bloch states in solids by applying magnetic field. The geometry of an object indicates its shape or the relationship of its parts to each ...

Bandgap refers to a region of an element’s crystal’s electronic band structure through which electrons can’t pass. Also referred to as an energy gap, bandgap is a concept in solid-state physics and ...

A team led by the Department of Energy’s Oak Ridge National Laboratory has found a rare quantum material in which electrons move in coordinated ways, essentially “dancing.” Straining the material ...
