Chiron气体的超流相变

Superfluid Transition in a Chiron Gas

George Chapline

摘要:

低温测量的磁化率的LSCO表明,超导转变与涡旋液体的消失。在这篇文章中,我们希望引起注意的事实是,自旋轨道类相互作用在一个不良的导电层状材料可以导致一种新的类型的量子基态的自旋极化类孤子载流子作为重要的量子自由度。在二维系统中,这些孤子是涡旋状的,而在三维系统中,它们是涡旋状的。在这两种情况下,有一个自然的机制,自旋向上和自旋向下的孤子的配对,我们发现,在低温下有一个交叉过渡的载流子密度之间的一个状态,其中的孤子是自由的和凝聚态的自旋向上和自旋向下的孤子在相邻层的配对的函数。

英文摘要:

Low temperature measurements of the magnetic susceptibility of LSCO suggest that the superconducting transition is associated with the disappearance of a vortex liquid. In this note we wish to draw attention to the fact that spin-orbit-like interactions in a poorly conducting layered material can lead to a new type of quantum ground state with spin polarized soliton-like charge carriers as the important quantum degree of freedom. In 2-dimensions these solitons are vortex-like, while in 3-dimensional systems they are monopole-like. In either case there is a natural mechanism for the pairing of spin up and spin down solitons, and we find that at low temperatures there is a cross-over transition as a function of carrier density between a state where the solitons are free and a condensate state where the spin up and spin down solitons in neighboring layers are paired.
