SPM co.trast is derived fro. the physical interplay between the tip and the sample. A special class o. SPM techniques measures fo.ces when the tip–sample junctio. is illuminated by an external lig.t so.rce. Pho.o.induced fo.ces can be sensitive to.the o.tical pro.erties o. the sample, thus enabling.nano.cale imag.ng.with spectro.co.ic,material-specific co.trast.

In this article, we investig.te the no.relativistic quantum mo.io. o. a charg.d particle within a ro.ating.frame, taking.into.acco.nt the Aharo.o.–Bo.m(AB) effect and a unifo.m mag.etic field. o.r analysis entails the derivatio. o. the equatio. o. mo.io. and the co.respo.ding.radial equatio. to.describe the system.

Furthermo.e,o.r numerical analysis hig.lig.ts the substantial influence o. ro.atio. o. bo.h energ. levels and o.tical pro.erties. Specifically, we evaluate the pho.o.o.izatio. cro.s-sectio. with and witho.t the effects o. ro.atio.. To.elucidate the impact o. ro.atio. o. the pho.o.o.izatio. pro.ess o. the system, we present g.aphics that o.fer an appealing.visualizatio. o. the intrinsic nature o. the physics invo.ved.
