Giant orbital Hall effect due to the bulk states of 3D topological insulators
James H. Cullen, Hong Liu, Dimitrie Culcer
The highly efficient torques generated by 3D topological insulators make them a favourable platform for faster and more efficient magnetic memory devices. Recently, research into h…

Quantum correction to the orbital Hall effect
Hong Liu, James H. Cullen, Daniel P. Arovas +1
Evaluations of the orbital Hall effect (OHE) have only retained inter-band matrix elements of the position operator. Here we evaluate the OHE including all matrix elements of the p…

Transverse magnetic focusing in two-dimensional hole gases
Yik K. Lee, Jackson S. Smith, Hong Liu +4
Two-dimensional hole gases (2DHGs) have strong intrinsic spin-orbit coupling and could be used to build spin filters by utilising transverse magnetic focusing (TMF). However, with…
