Comparing Hermitian and Non-Hermitian Quantum Electrodynamics
Jake Southall, Daniel Hodgson, Robert Purdy +1
In recent years, non-Hermitian quantum physics has gained a lot in popularity in the quantum optics and condensed matter communities in order to model quantum systems with varying…
Local photons
Daniel Hodgson, Jake Southall, Robert Purdy +1
The classical free-space solutions of Maxwell's equations for light propagation in one dimension include wave packets of any shape that travel at the speed of light. This includes…
Locally-acting mirror Hamiltonians
Jake Southall, Daniel Hodgson, Robert Purdy +1
Photons, i.e. the basic energy quanta of monochromatic waves, are highly non-localised and occupy all available space in one dimension. This non-local property can complicate the m…
Efficiency of free auxiliary models in describing interacting fermions: from the Kohn-Sham model to the optimal entanglement model
Kristian Patrick, Marcela Herrera, Jake Southall +2
Density functional theory maps an interacting Hamiltonian onto the Kohn-Sham Hamiltonian, an explicitly free model with identical local fermion densities. Using the interaction dis…
