# Orbital effect of an in-plane magnetic field on quantum transport in chaotic lateral dots

@article{Falko2002OrbitalEO, title={Orbital effect of an in-plane magnetic field on quantum transport in chaotic lateral dots}, author={Vladimir I. Fal’ko and Tom{\'a}{\vs} Jungwirth}, journal={Physical Review B}, year={2002}, volume={65}, pages={081306} }

We show that an in-plane magnetic field is able to break time-reversal symmetry of the orbital motion of electrons in two-dimensional semiconductor structures, due to the momentum-dependent inter-subband, mixing, which results in supression of weak localization effect. Then, we analyze the influence of the in-plane field on weak localization correction and universal fluctuations of conductance in large-area chaotic semiconductor quantum dots.
