New physical picture leads to a precise finite-size scaling of (3+1)-dimensional O(n) critical system

Since the establishment of the renormalization group theory, it has been known that systems of critical phenomena typically possess an upper critical dimension dc (dc=4 for the O(n) model), such that in spatial dimensions ...

Collective quantum effect: When electrons keep together

Many celestial objects such as stars or planets contain matter that is exposed to high temperatures and pressure—experts call it warm dense matter (WDM). Although this state of matter on earth only occurs in the earth's ...
