Ever since quantum mechanics first described particles, like electrons, as rippling waves, researchers have wondered if those ...

Scientists at Columbia University have discovered that electron waves can become trapped inside a metal, even when pathways ...

In a novel experiment, physicists have observed long range quantum coherence effects due to Aharonov-Bohm interference in a topological insulator-based device. This finding opens up a new realm of ...

Columbia University researchers report the first observation of electron waves trapped in place inside a two-dimensional ...

A multiwavelength laser source known as a frequency comb provides a new technique for atom interferometry, potentially leading to new tests of fundamental physics. Interfering with atoms. Two ...

Any standard textbook will tell you that the dynamics of quantum mechanics are based on two axioms—mathematical rules that ...

Thomas Young, born 250 years ago this week, was a polymath who made seminal contributions in fields from physics to Egyptology. But perhaps his most enduring legacy is proving Isaac Newton wrong about ...

Richard Feynman, one of the greatest physicists of the 20th century, once said something that should either comfort or terrify you: “Nobody understands quantum mechanics.” This wasn’t a confession of ...

Scientists at Columbia University have found that electron waves can remain trapped near atomic defects in a metal, despite ...
