A virtually connected probabilistic computer as a solver for higher-order, densely connected, or reconfigurable combinatorial optimisation problems
Amy J. Searle, Harry Youel, Fredrik Hasselgren +3
Recently, there has been growing interest in unconventional computing as an approach for solving NP-hard problems, by developing dedicated hardware to find solutions more efficient…
Self-correcting High-speed Opto-electronic Probabilistic Computer
Ramy Aboushelbaya, Annika Moslein, Hadi Azar +2
We present a novel self-correcting, high-speed optoelectronic probabilistic computer architecture that leverages source-device independent (SDI) quantum photonic p-bits integrated…
Search for black hole super-radiance using gravito-optic hetrodyne detection
Eduard Atonga, Ramy Aboushelbaya, Peter Norreys
Gravitational-wave astronomy plays a crucial role in early universe cosmology, dark matter detection, and black-hole merger studies. It is shown here that the heterodyne detection…
The gravito-optic effect
Eduard Atonga, Ramy Aboushelbaya, Peter A. Norreys
Gravitational waves have predominantly been detected using interferometric techniques, with standard approaches limited to 10 kHz and with modern advancements extending this bound…
Statistical theory of the broadband two-plasmon decay instability
Rusko T. Ruskov, Robert Bingham, Luis O. Silva +4
There is renewed interest in direct-drive inertial confinement fusion, following the milestone December 2022 3.15 MJ ignition result on the National Ignition Facility. A key obstac…
Gravitational waves from high-power twisted light
Eduard Atonga, Killian Martineau, Ramy Aboushelbaya +12
Recent advances in high-energy and high-peak-power laser systems have opened up new possibilities for fundamental physics research. In this work, the potential of twisted light for…
Efficient generation of new orbital angular momentum beams by backward and forward stimulated Raman scattering

The proton radiography diagnostic is widely used in laser-plasma experiments to make magnetic field measurements. Recent developments in analysis have enabled quantitative reconstr…
Methods for Extremely Sparse-Angle Proton Tomography
Ben T. Spiers, Ramy Aboushelbaya, Qingsong Feng +6
Proton radiography is a widely-fielded diagnostic used to measure magnetic structures in plasma. The deflection of protons with multi-MeV kinetic energy by the magnetic fields is u…
Nonlinear wakefields and electron injection in cluster plasma
Marko Mayr, Ben Spiers, Ramy Aboushelbaya +6
Laser and beam driven wakefields promise orders of magnitude increases in electric field gradients for particle accelerators for future applications. Key areas to explore include t…
Kinetic simulations of fusion ignition with hot-spot ablator mix
James D. Sadler, Yingchao Lu, Benjamin Spiers +9
Inertial confinement fusion fuel suffers increased X-ray radiation losses when carbon from the capsule ablator mixes into the hot-spot. Here we present one and two-dimensional ion…
Suprathermal Electrons from the Anti-Stokes Langmuir Decay Instability Cascade
Q. S. Feng, R. Aboushelbaya, M. W. Mayr +10
The study of parametric instabilities has played a crucial role in understanding energy transfer to plasma and, with that, the development of key applications such as inertial conf…
Orbital angular momentum coupling in elastic photon-photon scattering
