强相互作用二维Dirac费米子
Strongly Interacting Two-Dimensional Dirac Fermions
摘要：
我们展示了如何强相互作用的二维狄拉克费米子可以实现与超冷原子在一个二维光学正方形晶格与实验现实，固有的规范场，打破时间反演和反转对称性。我们发现显着的现象，在温度范围内的费米温度的十分之一左右，目前的实验技术：在零化学势，除了传统的s波超导相，非常规的超导性与非本地键配对出现。在温度与掺杂的相图中，非常规超导相呈现圆顶结构，让人想起高温超导体和重费米子的相图。
英文摘要：
We show how strongly interacting two-dimensional Dirac fermions can be realized with ultracold atoms in a two-dimensional optical square lattice with an experimentally realistic, inherent gauge field, which breaks time-reversal and inversion symmetries. We find remarkable phenomena in a temperature range around a tenth of the Fermi-temperature, accessible with present experimental techniques: at zero chemical potential, besides a conventional s-wave superconducting phase, unconventional superconductivity with non-local bond pairing arises. In a temperature versus doping phase diagram, the unconventional superconducting phase exhibits a dome structure, reminiscent of the phase diagram for high-temperature superconductors and heavy fermions.
