An experiment with ultracold atoms reveals that a strongly driven quantum system doesn’t always heat up as expected. In daily life, doing work on something over and over usually makes it warmer. You ...

A research team has developed a novel method for estimating the predictability of complex dynamical systems. Their work, "Time-lagged recurrence: A data-driven method to estimate the predictability of ...

A new proof demonstrates the power of arithmetic dynamics, an emerging discipline that combines insights from number theory and dynamical systems. Joseph Silverman remembers when he began connecting ...
