💘 How many kisses can one sphere receive?
First studied by Newton in 1694, the Kissing Number Problem asks how many non-overlapping spheres can touch a central one.
A team led by Peking University introduces PackingStar, a reinforcement learning system that sets new records in dimensions 25–31.

Randomness usually destroys order. But what if the right kind of randomness could preserve it?
#PekingUniversity researchers and collaborators take on the “heating problem” in driven quantum systems with an unexpected approach: structured randomness that stabilizes long-lived prethermal states.
