Manifestation of a non-Abelian Berry phase in a p -type semiconductor system
Tommy Li,L. A. Yeoh,Ashok Srinivasan,Oleh Klochan,David A. Ritchie,Michelle Y. Simmons,Oleg P. Sushkov,Alex R. Hamilton +7 more
TL;DR: In this paper, a non-Abelian gauge field was observed in a spin-orbit coupled quantum system, where the gauge field manifested itself in quantum magnetic oscillations of a hole doped two-dimensional (2D) GaAs heterostructure.

Using a tunable quantum wire to measure the large out-of-plane spin splitting of quasi two-dimensional holes in a GaAs nanostructure
Ashok Srinivasan,L. A. Yeoh,Oleh Klochan,Theodore P. Martin,J. C. H. Chen,Adam P. Micolich,Alex R. Hamilton,Dirk Reuter,Andreas D. Wieck +8 more
TL;DR: In this article, the out-of-plane g-factor for quasi-2D holes in a (100) GaAs heterostructure using a variable width quantum wire is studied.

Noncollinear paramagnetism of a GaAs two-dimensional hole system.
L. A. Yeoh,Ashok Srinivasan,Oleh Klochan,Roland Winkler,Ulrich Zülicke,Michelle Y. Simmons,David A. Ritchie,Michael Pepper,Alex R. Hamilton +8 more
TL;DR: It is demonstrated that an in-plane magnetic field can generate an out-of-plane component of magnetization in a low-symmetry hole system, creating new possibilities for spin manipulation.
New signatures of the spin gap in quantum point contacts
K. L. Hudson,Ashok Srinivasan,Olga Goulko,J. Adam,Qingwen Wang,L. A. Yeoh,Oleh Klochan,Ian Farrer,David A. Ritchie,Arne Ludwig,Andreas D. Wieck,J. von Delft,Alex R. Hamilton +12 more
TL;DR: In this article, the 1D channel in a series of low disorder p-type GaAs quantum point contacts, where spin-orbit and hole-hole interactions are strong, is studied and an alternative signature for probing spin gaps, which is insensitive to disorder, based on the linear and non-linear response to the orientation of the applied magnetic field, is presented.
Piezoelectric rotator for studying quantum effects in semiconductor nanostructures at high magnetic fields and low temperatures
L. A. Yeoh,Ashok Srinivasan,Theodore P. Martin,Oleh Klochan,Adam P. Micolich,Alex R. Hamilton +5 more
TL;DR: In this paper, the authors report the design and development of a piezoelectric sample rotation system, and its integration into an Oxford Instruments Kelvinox 100 dilution refrigerator, for orientation-dependent studies of quantum transport in semiconductor nanodevices at millikelvin temperatures in magnetic fields up to 10T.
