Recovering What Breaks in a Trapped-Ion Quantum Simulation of a Lattice Gauge Theory
Hassan Ugail
A recent trapped-ion experiment realised a lattice gauge theory with the gauge field in the internal states of the ions and bosonic matter in their vibrations. We showed earlier th…

Reliable Weyl Diagnostics for an Inhomogeneous Universe in Numerical Relativity
Hassan Ugail
The electric and magnetic parts of the Weyl tensor provide a geometric diagnostic for describing the local gravitational structure of an inhomogeneous universe, and they allow us t…

Geometric Phase-Space Structure in Cosmological Solutions of Einstein's Field Equations
Hassan Ugail
Einstein field equations allow cosmological dynamics to depart from the Friedmann-Lemaitre-Robertson-Walker (FLRW) idealisation in several physically different ways. Matter may bec…
