费米凝聚

恩里科·费米

费米凝聚(Fermionic condensate):类似于玻色-爱因斯坦凝聚态,由大量费米子占据同一量子态形成。由于泡利不兼容原理,不同的费米子不能占据同一量子态,因此费米子不能像玻色子那样直接形成玻色-爱因斯坦凝聚态。不过科学家把两个费米子结合在一起成为具有玻色子性质的“费米子对”即库柏对,这样使费米子对冷凝,成为费米凝聚。

Fermionic condensate 费米凝聚

A fermionic condensate is a superfluid phase formed by fermionic particles at low temperatures. It is closely related to the Bose–Einstein condensate, a superfluid phase formed by bosonic atoms under similar conditions. Unlike the Bose–Einstein condensates, fermionic condensates are formed using fermions instead of bosons. The earliest recognized fermionic condensate described the state of electrons in a superconductor; the physics of other examples including recent work with fermionic atoms is analogous. The first atomic fermionic condensate was created by a team led by Deborah S. Jin in 2003. A chiral condensate is an example of a fermionic condensate that appears in theories of massless fermions with chiral symmetry breaking.
