磁场诱导的手征粒子-空穴凝聚体
Magnetic field induced chiral particle-hole condensates
摘要：
我们证明了在有磁场存在的情况下，手征粒子-空穴凝聚总是由一个角动量不为零的数守恒基态诱导而成。磁场的相互作用起源于与手征态的内禀轨道矩的耦合，当磁场垂直于平面施加时。根据我们的数值计算结果，诱导机制实际上是温度无关的，提供这些状态的鲁棒性高达高温。这为操纵这类复杂状态产生的异常霍尔响应打开了大门，同时也表明手性粒子-空穴凝聚体可能隐藏在各种复杂材料中。
英文摘要：
We demonstrate that a chiral particle-hole condensate is always induced by a number-conserving ground state of non-zero angular momentum in the presence of a magnetic field. The magnetic interaction originates from the coupling with the intrinsic orbital moment of the chiral state when the field is applied perpendicularly to the plane. According to our numerical results the induction mechanism is practically temperature independent providing robustness to these states up to high temperatures. This opens the door for manipulating the anomalous Hall response resulting from this intricate class of states for technological applications while it also suggests that chiral particle-hole condensates may be hidden in various complex materials.
