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. 
Orbital effects of in-plane magnetic fields probed by mesoscopic conductance fluctuations
We use the high sensitivity to magnetic flux of mesoscopic conductance fluctuations in large quantum dots to investigate changes in the two-dimensional electron dispersion caused by an in-plane
Orbital effects of a strong in-plane magnetic field on a gate-defined quantum dot
We theoretically investigate the orbital effects of an in-plane magnetic field on the spectrum of a quantum dot embedded in a two-dimensional electron gas (2DEG). We derive an effective

TLDR
In-plane magnetic-field-assisted spectroscopy allows extraction of the in-plane orientation and full 3D size parameters of the quantum mechanical orbitals of a single electron GaAs lateral quantum dot with subnanometer precision, demonstrating a versatile tool for quantum dots with one dominant axis of strong confinement.
Weak localization and conductance fluctuations in a quantum dot with parallel magnetic field and spin-orbit scattering
In the presence of both spin-orbit scattering and a magnetic field the conductance of a chaotic GaAs quantum dot displays quite a rich behavior. Using a Hamiltonian derived by Aleiner and Fal’ko
Conductance Fluctuations and partially broken Spin Symmetries in Quantum Dots
Conductance fluctuations in GaAs quantum dots with spin-orbit and Zeeman coupling are investigated experimentally and compared to a random matrix theory formulation that defines a number of regimes
Quantum in-plane magnetoresistance in 2D electron systems
Studies of low-dimensional electron systems subject to an in-plane magnetic field have come to the focus of intense attention recently. In several experiments the influence of an in-plane magnetic
Parallel magnetic-field-induced conductance fluctuations in one- and two-subband ballistic quantum dots
We report on conductance fluctuations of ballistic quantum dots in a strictly parallel magnetic field B. The quantum dots are patterned in two-dimensional electron gases (2DEG's), confined to 15- and
Orbital effect, subband depopulation, and conductance fluctuations in ballistic quantum dots under a tilted magnetic field.
Using two-dimensional electron gases (2DEGs) confined to wide and narrow quantum wells, we study the magnetoconductance of ballistic quantum dots as a function of the well width and the tilt angle of
Coherence and Spin in GaAs Quantum Dots
This thesis describes a number of experiments performed in quantum dots as well as 2D systems fabricated in GaAs/AlGaAs 2D electron gases. The focus of the studies is set on spin, coherence and
