A team led by Robert Keil and Tommaso Faleo from the Department of Experimental Physics has investigated the relationship between entanglement and interference in quantum systems of more than two ...

The Galaxy Express 999 runs into the darkness of space. If it were a train, you could point to the tracks it passed. But what ...

Waves can reinforce each other, and they can also cancel each other out.Last time, I talked about how various "waves" are constantly passing back and forth around us. I spoke about how, using ...

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 ...

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 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 ...

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 ...

Tim Kovachy is in the Department of Physics and Astronomy and at the Center for Fundamental Physics, Northwestern University, Evanston, Illinois 60208, USA. Quantum mechanics predicts that single ...
