Ever since quantum mechanics first described particles, like electrons, as rippling waves, researchers have wondered if those waves could be trapped in place. Writing today in Science a century later, ...

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 ...

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

Any standard textbook will tell you that the dynamics of quantum mechanics are based on two axioms—mathematical rules that allow us to theoretically compute the outcome of an experiment. Surprisingly, ...

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 ...

A collaboration of Professor Szameit's research group at the University of Rostock with researchers from the Albert-Ludwigs-Universität Freiburg has succeeded in stabilizing the interference of two ...

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

Fig. 1 THz wave generation from MoS2 through quantum interference. (a) Schematic diagram of THz wave generation from MoS2 under two-color light excitation at normal incidence. (b) THz waveforms ...

Scientists at Columbia University have found that electron waves can remain trapped near atomic defects in a metal, despite the availability of pathways for them to escape. The findings confirm ...
