论文摘要
我们研究了整数量子大厅在散装填充因子2处的远距离库仑相互作用对两电体散射的影响。分裂步骤傅立叶方法的平行版在2D电位背景中演变出确切的两粒子波函数,从而繁殖了由逼近的杂物状态,由代表载体式浪费的extrative apriatiand odrapter的效果,由代替载体代表载体。我们比较了库仑排斥在最终的两电子波函数中引起的空间移位,该空间偏移是根据两个不可区分的电子根据其Landau指数初始初始配置初始化的可区分的电子,并分析其束概率及其筛选效果。我们最终证明了本工作制度是一种两倍的条件相变,以产生产品状态的纠缠。
We investigate the effect of long-range Coulomb interaction on the two-electron scattering in the integer quantum Hall regime at bulk filling factor 2. A parallel version of the Split-Step Fourier method evolves the exact two-particle wave function in a 2D potential background reproducing the effect of depleting gates in a realistic heterostructure, with the charge carrier represented by a localized wavepacket of edge states. We compare the spatial shift induced by Coulomb repulsion in the final two-electron wave function for two indistinguishable electrons initialized in different configurations according to their Landau index, and analyze their bunching probability and the effect of screening. We finally prove the feasibility of the present operating regime as a two-qubit conditional phase shifter to generate entanglement from product states.
