If a drop of creamer falls from a spoon into a swirling cup of coffee, the whirlpool drags the drop into rotation. But what would happen if the coffee had no friction—no way to pull the drop into a synchronized spin?

Simulating computationally complex many-body problems on a quantum simulator has great potential to deliver insights into physical, chemical and biological systems. Physicists had previously implemented Hamiltonian dynamics ...
Theoretical physicists from Trinity College Dublin have found a deep link between one of the most striking features of quantum mechanics—quantum entanglement—and thermalisation, which is the process in which something ...
