Dynamical phase transitions in the quantum world are wildly noisy and chaotic. They don’t look anything like the phase transitions we observe in our everyday world. In Colorado, we see phase transitions caused by temperature changes all the time: snow banks melting in the spring, water boiling on the stove, slick spots on the sidewalk after the first freeze. Quantum phase transitions happen,...

News Flash! The Rey group has discovered another good reason for using alkaline-earth atoms, such as strontium (Sr) or Ytterbium (Yb), in experimental quantum simulators. Quantum simulators are systems that mimic interesting materials or mathematical models in a very controlled way. The new reason for using alkaline earth atoms in such systems comes from the fact that their nuclei come in as...

A fundamental assumption of quantum information science is that there are degrees of freedom in quantum matter with long-lived coherence suitable for realizing controllable quantum bits--the fundamental information units of quantum information and computation. The existence of such degrees of freedom and the irreducibly quantum features of their states reveals fundamental features of the...
