Anisotropic scattering rates in strain-tuned SrRuO
Ben Currie, David T. S. Perkins, Evgeny Kozik +2
Motivated by recent angle-resolved photoemission spectroscopy (ARPES) experiments, we analyze the temperature, frequency, and momentum dependence of the single-particle scattering…
Effects of high-order Van Hove singularities on exciton and trion energy dispersions
Lewis J. Burke, Mark T. Greenaway, Joseph J. Betouras
We investigate the effects of Van Hove singularities in the electronic band structure of two-dimensional semiconductors on the energy dispersion of excitons and positive trions. In…
Designing Topological High-Order Van Hove Singularities: Twisted Bilayer Kagomé
David T. S. Perkins, Anirudh Chandrasekaran, Joseph J. Betouras
The interplay of high-order Van Hove singularities and topology plays a central role in determining the nature of the electronic correlations governing the phase of a system with u…
Brightening dark excitons and trions in systems with a Mexican-hat energy dispersion: example of InSe
Lewis J. Burke, Mark T. Greenaway, Joseph J. Betouras
We investigate the properties of momentum-dark excitons and trions formed in two-dimensional (2D) materials that exhibit an inverted Mexican-hat-shaped dispersion relation, taking…
