Multi-particle quantum systems within the Worldline Monte Carlo formalism
Ivan Ahumada, Max Badcott, James P. Edwards +6
We extend the Worldline Monte Carlo approach to computationally simulating the Feynman path integral of non-relativistic multi-particle quantum-mechanical systems. We show how to g…
Microcausality and Tunneling Times in Relativistic Quantum Field Theory
Mohammed Alkhateeb, Alex Matzkin
We show, in the framework of a space-time resolved relativistic quantum field theory approach to tunneling, that microcausality precludes superluminal tunneling dynamics. More spec…
Investigating Techniques to Optimise the Layout of Turbines in a Windfarm using a Quantum Computer
James Hancock, Matthew J. Craven, Craig McNeile +1
This paper investigates Windfarm Layout Optimization (WFLO), where we formulate turbine placement considering wake effects as a Quadratic Unconstrained Binary Optimization (QUBO) p…
Monte Carlo generation of localised particle trajectories
Ivan Ahumada, James P. Edwards
We introduce modifications to Monte Carlo simulations of the Feynman path integral that improve sampling of localised interactions. The new algorithms generate trajectories in simp…
Quantum Brain Networks: a Perspective
E. R. Miranda, S. Venkatesh, C. Hernani-Morales +3
We propose Quantum Brain Networks (QBraiNs) as a new interdisciplinary field integrating knowledge and methods from neurotechnology, artificial intelligence, and quantum computing.…
Renormalisation group flow of the Jaynes-Cummings model
Anton Ilderton
The Jaynes-Cummings model is a cornerstone of light-matter interactions. While finite, the model provides an illustrative example of renormalisation in perturbation theory. We show…
