Spin Hall Effect: Symmetry Breaking, Twisting, and Giant Disorder Renormalization
David T. S. Perkins, Alessandro Veneri, Aires Ferreira
Atomically-thin materials based on transition metal dichalcogenides and graphene offer a promising avenue for unlocking the mechanisms underlying the spin Hall effect (SHE) in hete…
Ultra-Fast All-Electrical Universal Nano-Qubits
David T. S. Perkins, Aires Ferreira
We propose how to create, control, and read-out real-space localized spin qubits in proximitized finite graphene nanoribbon (GNR) systems using purely electrical methods. Our propo…
Spintronics in 2D graphene-based van der Waals heterostructures
David T. S. Perkins, Aires Ferreira
Spintronics has become a broad and important research field that intersects with magnetism, nano-electronics, and materials science. Its overarching aim is to provide a fundamental…
Weak Localisation Driven by Pseudospin-Spin Entanglement
Frederico Sousa, David T. S. Perkins, Aires Ferreira
At low temperatures, quantum corrections, originating from the interference of the many paths an electron may take between two points, tend to dominate the transport properties of…
Nonperturbative approach to interfacial spin-orbit torques induced by Rashba effect
Alessandro Veneri, David T. S. Perkins, Aires Ferreira
Current-induced spin-orbit torque (SOT) in normal metal/ferromagnet (NM/FM) bilayers bears great promise for technological applications, but the microscopic origin of purely interf…
Twist Angle Controlled Collinear Edelstein Effect in van der Waals Heterostructures
Alessandro Veneri, David T. S. Perkins, Csaba G. Péterfalvi +1
The generation of spatially homogeneous spin polarization by application of electric current is a fundamental manifestation of symmetry-breaking spin--orbit coupling (SOC) in solid…
Fluctuation Spectroscopy in Granular Superconductors with Application to Boron-doped Nanocrystalline Diamond
David T. S. Perkins, Georgina M. Klemencic, Jonathan M. Fellows +1
We perform a detailed calculation of the various contributions to the fluctuation conductivity of a granular metal close to its superconducting transition. We find three distinct r…
Phase Slips and Metastability in Granular Boron-doped Nanocrystalline Diamond Microbridges
G. M. Klemencic, D. T. S. Perkins, J. M. Fellows +7
A phase slip is a localized disturbance in the coherence of a superconductor allowing an abrupt 2 phase shift. Phase slips are a ubiquitous feature of one-dimensional supercondu…
Drude Conductivity of a Granular System
David T S Perkins, Robert A Smith
We present a complete derivation of the granular analogue to Drude conductivity using diagrammatic methods. The convergence issues arising when changing the order of momentum and f…
Exactness of Bohr-Sommerfeld quantisation for two non-central potentials
David T. S. Perkins, Robert A. Smith
In this paper we demonstrate the integrability of the Hamilton-Jacobi equation for two non-central potentials in spherical polar coordinates, and present complete solutions for the…
