CdTe and HgTe doped with V, Cr, and Mn -- prospects for the quantum anomalous Hall effect
Giuseppe Cuono, Carmine Autieri, Tomasz Dietl
Using first principle calculations we examine properties of (Cd,V)Te, (Cd,Cr)Te, (Hg,V)Te, and (Hg,Cr)Te relevant to the quantum anomalous Hall effect (QAHE), such as the position…
Staggered Dzyaloshinskii-Moriya inducing weak ferromagnetism in centrosymmetric altermagnets and weak ferrimagnetism in noncentrosymmetric altermagnets
Carmine Autieri, Raghottam M Sattigeri, Giuseppe Cuono +1
The Dzyaloshinskii-Moriya interaction (DMI) has explained successfully the weak ferromagnetism in {\it some} centrosymmetric antiferromagnets. However, in the last years, it was ge…
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…
Interplay between altermagnetism and nonsymmorphic symmetries generating large anomalous Hall conductivity by semi-Dirac points induced anticrossings
Amar Fakhredine, Raghottam M. Sattigeri, Giuseppe Cuono +1
We investigate the interplay between altermagnetic spin-splitting and nonsymmorphic symmetries using the space group no. 62 as a testbed. Studying different magnetic orders by mean…
Spin-orbit insulating phase in SnTe cubic nanowires: consequences on the topological surface states
Ghulam Hussain, Kinga Warda, Giuseppe Cuono +1
We investigate the electronic, structural and topological properties of the SnTe and PbTe cubic nanowires using ab-initio calculations. Using standard and linear-scale density func…
Altermagnetic surface states: towards the observation and utilization of altermagnetism in thin films, interfaces and topological materials
Raghottam M Sattigeri, Giuseppe Cuono, Carmine Autieri
The altermagnetism influences the electronic states allowing the presence of non-relativistic spinsplittings. Since altermagnetic spin-splitting is present along specific k-paths o…
Orbital-selective altermagnetism and correlation-enhanced spin-splitting in transition metal oxides
Giuseppe Cuono, Raghottam M. Sattigeri, Jan Skolimowski +1
We investigate the altermagnetic properties of strongly-correlated transition metal oxides considering the family of the quasi two-dimensional A2BO4 and three-dimensional ABO3. As…
Pattern Formation by Electric-field Quench in Mott Crystal
Nicolas Gauquelin, Filomena Forte, Daen Jannis +10
The control of Mott phase is intertwined with the spatial reorganization of the electronic states. Out-of-equilibrium driving forces typically lead to electronic patterns that are…
Ab-initio overestimation of the topological region in Eu-based compounds
Giuseppe Cuono, Raghottam M. Sattigeri, Carmine Autieri +1
An underestimation of the fundamental band gap values by the density functional theory within the local density approximation and associated approaches is a well-known challenge of…
Current driven insulator-to-metal transition without Mott breakdown in CaRuO
Davide Curcio, Charlotte E. Sanders, Alla Chikina +16
The electrical control of a material's conductivity is at the heart of modern electronics. Conventionally, this control is achieved by tuning the density of mobile charge carriers.…
Correlation-driven topological transition in Janus VSiGeP2As2
Ghulam Hussain, Amar Fakhredine, Rajibul Islam +3
The appearance of intrinsic ferromagnetism in 2D materials opens the possibility of investigating the interplay between magnetism and topology. The magnetic anisotropy energy (MAE)…
Topological transition in Pb1-xSnxSe using Meta-GGA
Rajibul Islam, Giuseppe Cuono, Nguyen M. Nguyen +2
We calculate the mirror Chern number (MCN) and the band gap for the alloy Pb1-xSnxSe as a function of the concentration x by using virtual crystalline approximation. We use the ele…

Giuseppe Cuono, Ghulam Hussain, Amar Fakhredine +1
We reproduce the mirror Chern number phase diagram for the quaternary compound Pb1-xSnxSe1-yTey combining accurate density functional theory and tight-biding model. The tight bindi…
