Quantum emitter in a plasmonic field: an orientation generalised model
Harini Hapuarachchi, Jesse A. Vaitkus, Jared H. Cole
When a quantum emitter (QE) is placed in close proximity to a plasmonic metal nanoparticle (MNP) within an external optical field, a dipole-dipole coupling arises, resulting in a h…
A quantum algorithm for solving open system dynamics on quantum computers using noise
Juha Leppäkangas, Nicolas Vogt, Keith R. Fratus +6
In this paper we present a quantum algorithm that uses noise as a resource. The goal of our quantum algorithm is the calculation of operator averages of an open quantum system evol…
The effect of magnetic impurity scattering on transport in topological insulators
Jesse A. Vaitkus, Cong Son Ho, Jared H. Cole
Charge transport in topological insulators is primarily characterised by so-called topologically projected helical edge states, where charge carriers are correlated in spin and mom…
NanoNET: an extendable Python framework for semi-empirical tight-binding models
M. V. Klymenko, J. A. Vaitkus, J. S. Smith +1
We present a novel open-source Python framework called NanoNET (Nanoscale Non-equilibrium Electron Transport) for modelling electronic structure and transport. Our method is based…
The effect of atomic structure on the electrical response of aluminium oxide tunnel junctions
M. J. Cyster, J. S. Smith, J. A. Vaitkus +3
Many nanoelectronic devices rely on thin dielectric barriers through which electrons tunnel. For instance, aluminium oxide barriers are used as Josephson junctions in superconducti…
Probing charge carrier movement in organic semiconductor thin films via nanowire conductance spectroscopy
M. V. Klymenko, J. A. Vaitkus, J. H. Cole
Understanding the movement of charge within organic semiconducting films is crucial for applications in photo-voltaics and flexible electronics. We study the sensitivity of the ele…
Büttiker probes and the Recursive Green's Function; an efficient approach to include dissipation in general configurations
Jesse A. Vaitkus, Jared H. Cole
An efficient and compact approach to the inclusion of dissipative effects in Non-Equilibrium Green's Function (NEGF) simulations of electronic systems is introduced. The algorithm…
Digital Waveguide Adiabatic Passage Part 2: Experiment
Vincent Ng, Jesse A. Vaitkus, Zachary J. Chaboyer +5
Using a femtosecond laser writing technique, we fabricate and characterise three-waveguide digital adiabatic passage devices, with the central waveguide digitised into five discret…
Digital Waveguide Adiabatic Passage Part 1: Theory
Jesse A. Vaitkus, M. J. Steel, Andrew D. Greentree
Spatial adiabatic passage represents a new way to design integrated photonic devices. In conventional adiabatic passage designs require smoothly varying waveguide separations. Here…
Electronic transport in Si:P delta-doped wires
J. S. Smith, D. W. Drumm, A. Budi +3
Despite the importance of Si:P delta-doped wires for modern nanoelectronics, there are currently no computational models of electron transport in these devices. In this paper we pr…
Digital three-state adiabatic passage
Jesse A. Vaitkus, Andrew D. Greentree
We explore protocols for three-state adiabatic passage where the tunnel matrix elements are varied digitally, rather than smoothly as is the case with conventional adiabatic passag…
