标题： Particle-Flux Separation of Electrons in the Half-Filled Landau Level: Chargeon-Fluxon Approach

摘要： 粒子通量分离机制在与非相对论费米子耦合的陈-西蒙斯规范理论中通过非微扰方法进行研究。 这个问题对于分数量子霍尔效应的复合费米子方法非常重要。 我们表明，由于电子之间的排斥相互作用，在低温下半填充分立能级中的复合费米子是稳定的准激发态。 显示英文摘要

摘要： Mechanism of the particle-flux separation in the Chern-Simons gauge theory coupled with nonrelativistic fermions is studied in a nonperturbative method. This problem is very important for the composite fermion approach to the fractional quantum Hall effect. We show that due to repulsive interactions between electrons the composite fermions are stable quasiexcitations in the half-filled Landau level at low temperature.
