Defect Geometry Selects Polar and Anomalous Hall Phases in Two-Dimensional Altermagnets
Xujia Gong, Amar Fakhredine, Hosein Alavi-Rad +6
Point defects in altermagnets can create phases absent in the pristine host by selectively breaking crystal symmetries. Combining symmetry analysis, first-principles calculations,…
Effective model and electron correlations in trilayer nickelate superconductor LaNiO
Peng-Fei Tian, Hao-Tian Ma, Xing Ming +2
Recently, signatures of superconductivity with critical temperature from 20 to 30 K have been reported in pressured trilayer nickelate LaNiO through a pressure-induc…
Dirac surface states, multiorbital dimerization and superconductivity in Nb- and Ta-based A15 compounds
Raghottam M. Sattigeri, Giuseppe Cuono, Ghulam Hussain +5
Using first-principle calculations, we investigate the electronic, topological and superconducting properties of NbX (X = Ge, Sn, Sb) and TaY (Y = As, Sb, Bi) A15 compounds…
Phase evolution of Ce-based heavy-fermion superconductors under compression: a combined first-principle and effective-model study
Hao-Tian Ma, Peng-Fei Tian, Da-Liang Guo +4
In many Ce-based superconductors, superconducting (SC) phases emerge or can be tuned in proximity to the antiferromagnetic (AF) quantum critical point (QCP), but so far the explici…
