Making a Fast Computational Tool Even Faster

Simons Foundation, June 2020

Alex Barnett takes a small silver tuning fork from his backpack, thwacks it against his desk and holds it to a microphone. On his computer, the musical tone appears as a steady succession of identical sine waves.

“It’s an A4, or the A above middle C,” says Barnett, who plays classical and jazz piano in addition to serving as group leader for numerical analysis at the Flatiron Institute’s Center for Computational Mathematics (CCM). “That’s 440 hertz, or 440 oscillations per second.”

Machine Learning Cracks Quantum Chemistry Conundrum

Simons Foundation, May 2020

A new machine learning tool can calculate the energy required to make — or break — a molecule with higher accuracy than conventional methods. While the tool can currently only handle simple molecules, it paves the way for future insights in quantum chemistry.

Columbia University, Flatiron Institute, Max Planck Society Launch Max Planck–New York City Center for Nonequilibrium Quantum Phenomena

Simons Foundation, November 2019

Columbia University, the Flatiron Institute in New York City and the Max Planck Society in Germany are joining forces. Their new partnership, called the Center for Nonequilibrium Quantum Phenomena, aims to understand, control and manipulate the uniquely useful properties of quantum materials.

‘Ringing’ Black Hole Validates Einstein’s General Relativity 10 Years Ahead of Schedule

Simons Foundation, September 2019

For the first time, astrophysicists have heard a black hole ringing like a bell. By reanalyzing the first black hole merger ever detected, the astrophysicists measured the gravitational wave ‘tones’ emitted following the event. The breakthrough comes 10 years earlier than expected and confirms that the properties of black holes are just as Einstein predicted in his theory of general relativity in 1915.
