d>1维费米-液体-非费米-液体量子相变理论

Theory of a Fermi-Liquid-to-Non-Fermi-Liquid Quantum Phase Transition in Dimensions d>1

T. R. Kirkpatrick, D. Belitz

摘要:

我们发展了一个理论的一个通用的不稳定性的费米液体在d>1的维反对形成一个Luttinger液体的状态。费米能级上的态密度是随后发生的量子相变的序参量,它由有效相互作用强度驱动。用标度理论和净电子的有效场理论得到了观测量的临界行为。在费米液相的序参数的磁化率,这是可测量的隧道,预计发散为1<d<3。

英文摘要:

We develop a theory for a generic instability of a Fermi liquid in dimension d>1 against the formation of a Luttinger-liquid-like state. The density of states at the Fermi level is the order parameter for the ensuing quantum phase transition, which is driven by the effective interaction strength. A scaling theory in conjunction with an effective field theoy for clean electrons is used to obtain the critical behavior of observables. In the Fermi-liquid phase the order-parameter susceptibility, which is measurable by tunneling, is predicted to diverge for 1<d<3.
