In new research appearing in Physical Review Letters, an international research team, including UC Davis physicists, has expanded the Fermi-Hubbard model, allowing for a more detailed exploration of materials and their properties. In the study, the researchers measured the equation of state for Ytterbium atoms in an optical lattice. Specifically, they used the fermionic isotope 173Yb, which is a metallic element with atoms that can adopt six possible states.
In new research, UC Davis philosopher Elaine Landry finds that the writings of Plato from 2,400 years ago show a better way to think about what’s real in mathematics.
The College of Letters and Science is investing $5 million in its instructional equipment and facilities to improve the educational experiences of students in L&S and across UC Davis. These investments have already transformed learning opportunities.
For his contributions to the development and application of atomistic and first principle simulations to understand the physical properties of materials and nanostructures, Professor of Chemistry Davide Donadio was recently named a fellow of the American Physical Society.
For her landmark work in the development and application of shock physics techniques to explain the origin and evolution of planetary systems, Sarah Stewart has been selected as an American Physical Society Fellow, a prestigious honor that no more than half of one percent of the society’s membership (excluding student members) are nominated for each year.
This week, Manuel Calderón de la Barca Sánchez returned to his alma mater in Mexico to host screenings of ‘Secrets of the Universe,’ an IMAX film that explores the formation of the universe through the eyes of Aggie researchers. Calderón de la Barca Sánchez, a UC Davis physics professor, hopes the film will inspire students to pursue STEM education and careers.
Early in the movie 'Oppenheimer,' J. Robert Oppenheimer (Cillian Murphy) visits the Berkeley laboratory where Ernest Lawrence is building a particle accelerator to study nuclear physics. The scene reminded me that the giant magnets from one of those accelerators later came to UC Davis, forming the core of the cyclotron at the Crocker Nuclear Laboratory on campus. It is one of several links between Oppenheimer, the Manhattan Project and UC Davis.
How did the universe become so good at hiding quantum physics?
In two new papers appearing in Physical Review Research, UC Davis and Los Alamos National Laboratory researchers introduce a new model to explain the phenomenon of decoherence, when a system’s behavior shifts from being explainable by quantum mechanics to being explainable by classical mechanics. The new model divorces the arrow of time from the go-to theoretical tool for understanding decoherence: the
Caldeira-Leggett model.
Associate Professor Rishidev Chaudhuri’s research sits in the nexus of mathematics,
physics and neuroscience. Chaudhuri studies processing strategies in the brain using
mathematics and physics. One direction of his research concerns the neural
underpinnings of decision-making, an avenue of research that’s making neuroscientists
rethink longstanding narratives about how the brain functions.
