Efficient prediction of highly anisotropic excitonic properties in the layered antiferromagnet CrSBr via time-dependent density functional theory

Ashwin Ramasubramaniam, Daniel Hernang\'omez-P\'erez, Javier Junquera, Mar\'ia Camarasa-G\'omez

A tuned hybrid density functional with on-site corrections accurately reproduces CrSBr gaps and exciton-magnetic coupling via TDDFT, enabling predictions of spin-canting shifts.

Claims

C1strongest claim

Using a tuned hybrid density functional with on-site corrections, we reproduce fundamental and optical gaps and quantitatively capture the interaction between excitonic transitions and magnetic order. We then employ this functional to investigate excitonic shifts induced by spin canting, that would result from applying an external magnetic field.

C2weakest assumption

The assumption that a single tuned hybrid functional with on-site corrections, calibrated to gaps, will quantitatively capture the exciton-magnetic coupling and spin-canting shifts without needing full many-body perturbation theory.

C3one line summary

A tuned hybrid TDDFT approach accurately predicts anisotropic excitonic properties and their coupling to magnetic order in CrSBr, including shifts from spin canting.
