论文摘要
量子关键领域的一个关键问题是了解相互作用的流动费用系统中量子相变的性质,这是通过对各种强相关材料进行实验的动机。近年来,人们对二维(2D)材料引起了很多关注,其中巡回费米子获得了伪偏僻的狄拉克分散剂,例如石墨烯,拓扑绝缘子表面和某些自旋液体。本文回顾了2D Dirac Fermions系统中量子相变的现象学和理论描述。
A key problem in the field of quantum criticality is to understand the nature of quantum phase transitions in systems of interacting itinerant fermions, motivated by experiments on a variety of strongly correlated materials. Much attention has been paid in recent years to two-dimensional (2D) materials in which itinerant fermions acquire a pseudo-relativistic Dirac dispersion, such as graphene, topological insulator surfaces, and certain spin liquids. This article reviews the phenomenology and theoretical description of quantum phase transitions in systems of 2D Dirac fermions.
