In the everyday world, governed by classical physics, the concept of equilibrium reigns. If you put a drop of ink into water, it will eventually evenly mix. If you put a glass of ice water on the ...

A new study links the universe’s expansion to quantum topology, suggesting that hidden mathematical structures may stabilize the cosmological constant in ways previously unrecognized.

Scientists have created a powerful new way to control quantum systems, achieving the first-ever demonstration of ...

In thermodynamics, an "adiabatic process" is a system change that transfers no heat in or out of the system. Any and all ...

A NOON state is a superposed quantum state where N particles are in one state "at the same time" and in another "at the same time". Here, the particles are trapped in two wells, within a trap formed ...

Thermodynamics and statistical physics provide a unified framework linking the macroscopic laws of energy, work, and entropy to the microscopic motions of particles. Thermodynamics, rooted in the laws ...

Scientists have found a way to make AI much better at predicting complex, chaotic systems by tapping into the unique power of ...

Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely ...

Neutrino physics. “Movies” of quantum phenomena. Many-body problems. New-to-nature catalytic reactions. These are just a few of the hot fields of research where UC Santa Barbara’s junior faculty are ...
