CCNY team in quantum algorithm breakthrough

Researchers led by City College of New York physicist Pouyan Ghaemi report the development of a quantum algorithm with the potential to study a class of many-electron quantums system using quantum computers. Their paper, ...

Quantum hall effect 'reincarnated' in 3-D topological materials

U.S. and German physicists have found surprising evidence that one of the most famous phenomena in modern physics—the quantum Hall effect—is "reincarnated" in topological superconductors that could be used to build fault-tolerant ...

Researchers observe exotic quantum particle in bilayer graphene

October 5, 2017—A team led by Cory Dean, assistant professor of physics at Columbia University, and James Hone, Wang Fong-Jen Professor of Mechanical Engineering at Columbia Engineering, has definitively observed an intensely ...

Physicists observe behavior of quantum materials in curved space

Light and matter are typically viewed as distinct entities that follow their own, unique rules. Matter has mass and typically exhibits interactions with other matter, while light is massless and does not interact with itself. ...

Researchers observe phase transition thought impossible

An ultrapure material taken to pressures greater than that in the depths of the ocean and chilled to temperatures colder than outer space has revealed an unexpected phase transition that crosses two different phase categories.
