Mathematicians Blake Temple and Zeke Vogler at the University of California, Davis, and Joel Smoller at the University of Michigan, Ann Arbor, worked out solutions to General Relativity without invoking dark energy. They argue that the equations show that the Friedmann space-time is actually unstable: Any perturbation — for example if the density of matter is a bit lower than average — pushes it over into an accelerating universe.
With the Center for Quantum Mathematics and Physics (QMAP), the college is creating an extraordinary environment where mathematicians and physicists will work side-by-side to explore quantum field theory, string theory, and quantum gravity.
A simple method for manufacturing extremely low-density palladium nanofoams could help advance hydrogen storage technologies, reports a new study from researchers in the UC Davis College of Letters and Science.
For the first time, astronomers have observed a celestial event through both conventional telescopes and gravitational waves. Assistant Professor Stefano Valenti helped detect the collision of two neutron stars and confirm these cataclysmic events are the source of gold, platinum and other heavy elements.
A special groundbreaking was held July 21 deep underground in South Dakota. Scientists, engineers and guests turned the first shovelfuls of the 800,000 tons of rock that will be excavated to build the Long Baseline Neutrino Facility (LBNF) at the Sanford Underground Research Facility.
Researchers from around the world recently converged at UC Davis for a five-day conference exploring emerging science in quantum field theory, string theory and quantum gravity. Organized by the Center for Quantum Mathematics and Physics (QMAP) at UC Davis, the conference brought together speakers from across the international physics and math community for talks and informal discussion about recent developments in physics.
In the College of Letters and Science magazine released in December 2016, we featured faculty and graduate students who provided expertise and insight into the big public issues of the day, from the parenting transgender kids, the political divide and immigration to climate change and poverty.
If Salvador Dali designed a science museum, it might look something like the plans for the Institute of Unknown Purpose, a surreal and playful pop-up institute that will blend science and art. Imagined by a UC Davis physicist and a British “mad scientist,” the Institute of Unknown Purpose will feature exhibits and activities that explore mathematical and scientific discovery.
