标题： Quantum Hall-like effect for neutral particles with magnetic dipole moments in a quantum dot

摘要： 我们在完全中性系统中预测了一类新的量子霍尔现象，证明了径向电场与偶极矩之间的相互作用可以诱导精确的$e^2/h$量化，而无需朗道能级或外部磁场。 与传统观念相反，我们的理论揭示了：(i) 线电荷的奇异性不会破坏拓扑保护，(ii) 仅从边界条件就可以出现量化自旋控制，(iii) 这种效应可维持到25 K，超过典型中性系统。 这些发现确立了电场工程作为一种超越磁学范式的拓扑物质可行途径。 显示英文摘要

摘要： We predict a new class of quantum Hall phenomena in completely neutral systems, demonstrating that the interplay between radial electric fields and dipole moments induces exact $e^2/h$ quantization without the need for Landau levels or external magnetic fields. Contrary to conventional wisdom, our theory reveals that: (i) the singularity of line charges does not destroy topological protection, (ii) spin-control of quantization emerges from boundary conditions alone, and (iii) the effect persists up to 25 K, surpassing typical neutral systems. These findings establish electric field engineering as a viable route to topological matter beyond magnetic paradigms.
