Engineering correlated phases through manipulation of Van Hove singularities
Thomas P. Sheerin, Maria Ramirez, Chris A. Hooley +1
Controlling the ordered phases of correlated electron systems remains a central challenge in quantum materials design. Divergences in the electronic density of states, known as Van…

Non-Fermi liquid induced by U(1) gauge field interactions: a functional renormalization group analysis
Thomas P. Sheerin, Chris A. Hooley
We study the non-Fermi-liquid state formed by an isotropic, degenerate Fermi gas in two spatial dimensions interacting with a U(1) gauge field. Our calculation uses the functional…
