Generating a topological anomalous Hall effect in a non-magnetic conductor
James H. Cullen, Pankaj Bhalla, Elizabeth Marcellina +2
The ordinary Hall effect is driven by the Lorentz force, while its anomalous counterpart occurs in ferromagnets. Here we show that the Berry curvature monopole of non-magnetic 2D s…
Optimal operation points for ultrafast, highly coherent Ge hole spin-orbit qubits
Zhanning Wang, Elizabeth Marcellina, A. R. Hamilton +4
Strong spin-orbit interactions make hole quantum dots central to the quest for electrical spin qubit manipulation enabling fast, low-power, scalable quantum computation. Yet it is…
Non-linear spin filter for non-magnetic materials at zero magnetic field
E. Marcellina, A. Srinivasan, F. Nichele +5
The ability to convert spin accumulation to charge currents is essential for applications in spintronics. In semiconductors, spin-to-charge conversion is typically achieved using t…
Signatures of quantum mechanical Zeeman effect in classical transport due to topological properties of two-dimensional spin-3/2 holes
E. Marcellina, Pankaj Bhalla, A. R. Hamilton +1
The Zeeman interaction is a quantum mechanical effect that underpins spin-based quantum devices such as spin qubits. Typically, identification of the Zeeman interaction needs a lar…
Electrical control of the Zeeman spin splitting in two-dimensional hole systems
Elizabeth Marcellina, Ashwin Srinivasan, Dmitry Miserev +6
Semiconductor holes with strong spin-orbit coupling allow all-electrical spin control, with broad applications ranging from spintronics to quantum computation. Using a two-dimensio…
Theory of Hole-Spin Qubits in Strained Germanium Quantum Dots
L. A. Terrazos, E. Marcellina, Zhanning Wang +8
We theoretically investigate the properties of holes in a SiGe/Ge/ SiGe quantum well in a perpendicular magnetic field that make them advantageous as qu…
Strong influence of spin-orbit coupling on magnetotransport in two-dimensional hole systems
Hong Liu, Elizabeth Marcellina, Alexander R. Hamilton +1
With a view to electrical spin manipulation and quantum computing applications, recent significant attention has been devoted to semiconductor hole systems, which have very strong…
Spin blockade as a probe of Zeeman interactions in hole quantum dots
Jo-Tzu Hung, Elizabeth Marcellina, Bin Wang +2
Spin-orbit coupling is key to all-electrical control of quantum-dot spin qubits, and is frequently stronger for holes than for electrons. Here we investigate Pauli spin blockade fo…
Spin-orbit interactions in inversion-asymmetric 2D hole systems: a variational analysis
E. Marcellina, A. R. Hamilton, R. Winkler +1
We present an in-depth study of the spin-orbit (SO) interactions occurring in inversion-asymmetric two-dimensional hole gases at semiconductor heterointerfaces. We focus on common…
