石墨烯N=0朗道能级的场致Kosterlitz-numerless跃迁
Field-induced Kosterlitz-Thouless transition in the N=0 Landau level of graphene
摘要：
在电荷中性点，石墨烯表现出非常不寻常的高电阻金属态，并在强磁场中转变为完全绝缘相。我们提出，在这种状态下的电流载体是XY谷赝自旋序参数的带电涡旋，这是一个传统的薄超导膜的双重情况。我们研究能量学和稳定性的存在下，这一阶段的混乱。
英文摘要：
At the charge neutral point, graphene exhibits a very unusual high resistance metallic state and a transition to a complete insulating phase in a strong magnetic field. We propose that the current carriers in this state are the charged vortices of the XY valley pseudospin order-parameter, a situation which is dual to a conventional thin superconducting film. We study energetics and the stability of this phase in the presence of disorder.
