Energy Symmetry Breaking of Dirac and Weyl Fermions in Magnetized Spinning Conical Geometries

Advanced Theory and Simulations, EarlyView.
Exact solutions for relativistic fermions in magnetized, spinning conical geometries reveal defect‐induced symmetry breaking between fermion and antifermion energies. Energy levels depend on the magnetic field, background geometry, and fractionalized spin. When the defect's spin dominates, quantum effects diminish.

Almost complex structures and geometric quantization

, 1996
We study two quantization schemes for compact symplectic manifolds with almost complex structures. The first of these is the Spin-c quantization. We prove the analog of Kodaira vanishing for the Spin-c Dirac operator, which shows that the index space of ...

Sleep Deprivation Activates a Conserved Lactate‐H3K18la‐RORα Axis Driving Neutrophilic Inflammation Across Species

Advanced Science, EarlyView.
Sleep deprivation triggers systemic immune activation characterized by neutrophil accumulation and cytokine release. This study reveals a conserved metabolic‒epigenetic mechanism whereby lactate‐induced H3K18 lactylation upregulates RORα expression, promoting neutrophilic inflammation.
