Imagine asking the biggest, most fundamental question of all: what is reality? How would you go about answering it? If you took the scientific approach, you'd go down to the smallest indivisible ...

What is superposition and wave/particle duality in quantum physics? All quantum particles exist in a state of superposition ...

In quantum mechanics, particles such as electrons act like waves and can even interfere with themselves—a striking and counterintuitive feature that defies our classical view of reality. We know this ...

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 ...

An atomic-scale double-slit experiment reveals how neighboring atoms vibrate together, offering a new way to study heat flow ...

The origin of the so-called 'beating' signal, whose identity has remained unknown in topological insulator nanowires for ...

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 ...
