Switching Persistent Supercurrent on an Atom Chip

Not Accessible

Your library or personal account may give you access

Abstract

Rubidium 87 atoms are trapped in an Ioffe-Pritchard potential generated with a persistent supercurrent that flows in a loop circuit patterned on a sapphire surface. To control the supercurrent on a surface, an on-chip thermal switch operated by a focused argon-ion laser is developed.
