Agents.jl: A performant and feature-full agent based modelling software of minimal code complexity
George Datseris, Ali R. Vahdati, Timothy C. DuBois
Agent based modelling is a simulation method in which autonomous agents interact with their environment and one another, given a predefined set of rules. It is an integral method f…
Proton acceleration by a pair of successive ultraintense femtosecond laser pulses
Julien Ferri, Lovisa Senje, Malay Dalui +12
We investigate the target normal sheath acceleration of protons in thin aluminum targets irradiated at relativistic intensity by two time-separated ultrashort (35 fs) laser pulses.…
Origins of plateau formation in ion energy spectra under target normal sheath acceleration
Timothy C. DuBois, Evangelos Siminos, Julien Ferri +2
Target normal sheath acceleration (TNSA) is a method employed in laser--matter interaction experiments to accelerate light ions (usually protons). Laser setups with durations of a…
Relativistic Vlasov-Maxwell modelling using finite volumes and adaptive mesh refinement
Benjamin Svedung Wettervik, Timothy Charles DuBois, Evangelos Siminos +1
The dynamics of collisionless plasmas can be modelled by the Vlasov-Maxwell system of equations. An Eulerian approach is needed to accurately describe processes that are governed b…
A 3D investigation of delocalised oxygen two-level defects in Josephson junctions
Timothy C. DuBois, Salvy P. Russo, Jared H. Cole
Environmental two-level systems (TLS) have been identified as significant decoherence sources in Josephson junction (JJ) based circuits. For such quantum devices to be functional,…
Dispersion of particles by a strong explosion
Timothy C. DuBois, Milan Jamriska, Alex Skvortsov
The dynamics of particle transport under the influence of localised high energy anomalies (explosions) is a complicated phenomena dependent on many physical parameters of both the…
Constructing ab initio models of ultra-thin Al-AlOx-Al barriers
Timothy C. DuBois, Martin J. Cyster, George Opletal +2
The microscopic structure of ultra-thin oxide barriers often plays a major role in modern nano-electronic devices. In the case of superconducting electronic circuits, their operati…
Atomic delocalisation as a microscopic origin of two-level defects in Josephson junctions
Timothy C. DuBois, Salvy P. Russo, Jared H. Cole
Identifying the microscopic origins of decoherence sources prevalent in Josephson junction based circuits is central to their use as functional quantum devices. Focussing on so cal…
Tracer dispersion in the turbulent convective layer
Alex Skvortsov, Milan Jamriska, Timothy C DuBois
Experimental results for passive tracer dispersion in the turbulent surface layer under convective conditions are presented. In this case, the dispersion of tracer particles is det…
Delocalised oxygen as the origin of two-level defects in Josephson junctions
Timothy C. DuBois, Manolo C. Per, Salvy P. Russo +1
One of the key problems facing superconducting qubits and other Josephson junction devices is the decohering effects of bi-stable material defects. Although a variety of phenomenol…
Statistical characterisation of bio-aerosol background in an urban environment
Milan Jamriska, Timothy C. DuBois, Alex Skvortsov
In this paper we statistically characterise the bio-aerosol background in an urban environment. To do this we measure concentration levels of naturally occurring microbiological ma…
Scaling laws of passive tracer dispersion in the turbulent surface layer
Alex Skvortsov, Milan Jamriska, Timothy C. DuBois
Experimental results for passive tracer dispersion in the turbulent surface layer under stable conditions are presented. In this case, the dispersion of tracer particles is determi…
