Band structure control in the altermagnetic candidate MnTe by temperature and strain

This study confirms the altermagnetic nature of hexagonal MnTe by demonstrating that its terahertz optical absorption, arising from spin-split bands, exhibits temperature-dependent behavior consistent with a ferromagnetic-like transition and strain-induced shifts that align with theoretical predictions of decreasing spin-splitting angles.

Ideal band structures for high-performance thermoelectric materials with band convergence

This paper utilizes a virtual spectral conductivity model to establish quantitative design principles for high-performance thermoelectric materials, demonstrating that optimal band convergence requires a band gap and energy separation exceeding approximately 5k_BT to suppress bipolar effects and maximize spectral conductivity through high band degeneracy, effective mass, and relaxation time.

Electric toroidal octupolar symmetry in pyrite FeS2_2 probed by Raman optical activity

This study demonstrates that Raman optical activity serves as a sensitive probe for electric toroidal octupolar symmetry in pyrite FeS2_2, evidenced by reproducible sign reversals of circular intensity differences on neighboring {111} faces that are uniquely associated with the doubly degenerate EgE_g phonon mode and confirmed by first-principles calculations.
