Puzzling effects Two quantum simulations have revealed unexpected behaviour at quantum phase transitions. (Courtesy: ...

A new way to measure the temperatures of objects by studying the effect of their black-body radiation on Rydberg atoms has ...

A programmable quantum simulator based on Rydberg atom arrays is used to study the collective dynamics of a quantum phase transition and observe the phenomenon of quantum coarsening. A hybrid ...

Conventional quantum mechanics didn't have such transitions, and Dirac's relativistic ... In particular, this reduces the value of the Rydberg constant by one part in a trillion.
