Rotating effects on the Hall conductivity in a quantum dot

Abstract

We investigate the behavior of the quantized Hall conductivity in a two-dimensional quantum system under rotating effects, a uniform magnetic field, and an Aharonov-Bohm (AB) flux tube. By varying the angular velocity and the AB flux, we analyze their impact on the formation, shifting, and structure of quantized Hall plateaus. Our results reveal that rotation modifies the energy spectrum, leading to slight shifts in the plateau positions and variations in their widths. Additionally, we identify Aharonov-Bohm-type oscillations in ${\sigma }_{\text{Hall}}$, which become more pronounced for lower values of the cyclotron frequency ${\omega }_c$, indicating enhanced quantum interference effects in the low-field regime. These oscillations are further modulated by $\Omega$, affecting their periodicity and amplitude. The interplay between the confinement frequency ${\omega }_0$, the cyclotron frequency ${\omega }_c$, and the rotational effects plays a crucial role in determining the overall behavior of ${\sigma }_{\text{Hall}}$. Our findings provide insights into the interplay between rotation, magnetic field, and quantum interference effects, which are relevant for experimental investigations of quantum Hall systems in rotating systems.
