Further advances in the study of holography resulted in time-resolved optical holography, successfully realized in the femtosecond regime for enhanced spatial resolution in time-resolved photoemission ...

If you ask people what a hologram is, they’ll probably describe the 3D light projections of science-fiction films — such as the vision of Princess Leia floating in free space in the 1977 film Star ...

Because the electrons can pass through either slit, the waves emerging on the other side can interact and recombine in complex ways, producing an interference pattern. When the peak of one wave ...

Thomas Young’s double-slit experiment is famous for demonstrating the principle of interference. Andrew Murray explains why it’s now possible to carry out an equivalent experiment using lasers that ...

In combined theoretical and experimental work, physicists introduce and demonstrate a novel mechanism for electron optics in two-dimensional solid-state systems. The discovery opens up a route to ...

IN 1924, Prince Louis de Broglie put forward the thesis that all material particles, and in particular electrons, have properties analogous to those of a train of waves. This view, which is now ...
