Transient Parity Violation during Inflation: Implications for PTA Gravitational Waves

Gianmassimo Tasinato · 2026

We investigate the consequences of a transient phase of enhanced parity violation during inflation. Modeling this phase through a time-localized Chern--Simons-like coupling, we show that it amplifies …

Crystal-Field Symmetry Constraints in Layered Honeycomb ErBr$_3$

Biaoyan Hu, Mingyuan Hu, Franz Demmel, Andrey A. Podlesnyak, Jiaqing He, Liusuo Wu · 2026

We show that the local crystal-field symmetry of ErBr$_3$ enforces $\langle \psi_\pm | J^{\pm} | \psi_\mp \rangle = 0$ within the ground-state Kramers doublet, thereby removing the lowest-order transv…
