Conditions for orbital selective altermagnetism in SrRuO: tight binding model, similarities with cuprates and implications on superconductivity
Carmine Autieri, Giuseppe Cuono, Debmalya Chakraborty +2
The vibrational modes in SrRuO easily induce octahedral rotations without tilting. Being on the verge of a magnetic instability, such propensity of octahedral rotation may…
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…
Double-helix magnetic order in CrAs with Pnma space group
Giuseppe Cuono, Alfonso Romano, Canio Noce +1
The transition metal pnictide CrAs exhibits superconductivity in the vicinity of a helimagnetic phase, where it has been found that the propagation vector is parallel to the c axis…
Magnetic instabilities in quasi-one-dimensional Cr-based material
Armando Galluzzi, Giuseppe Cuono, Alfonso Romano +4
The magnetic response of a K2Cr3As3 sample has been studied by means of dc magnetization measurements as a function of magnetic field (H) at different temperatures ranging from 5 K…
Dimensionality of the superconductivity in the transition metal pnictide WP
Angela Nigro, Giuseppe Cuono, Pasquale Marra +9
We report theoretical and experimental results on the transition metal pnictide WP. The theoretical outcomes based on tight-binding calculations and density functional theory indic…
Spin-orbit coupling effects on the electronic properties of the pressure-induced superconductor CrAs
Giuseppe Cuono, Carmine Autieri, Giuseppe Guarnaccia +4
We present the effects of spin-orbit coupling on the low-energy bands and Fermi surface of the recently discovered pressure-induced superconductor CrAs. We apply the Löwdin down-fo…
Multiple band-crossings and Fermi surface topology: role of double nonsymmorphic symmetries in MnP-type crystal structures
Giuseppe Cuono, Filomena Forte, Mario Cuoco +4
We use relativistic ab-initio methods combined with model Hamiltonian approaches to analyze the normal-phase electronic and structural properties of the recently discovered WP supe…
A minimal tight-binding model for the quasi-one-dimensional superconductor K2Cr3As3
Giuseppe Cuono, Carmine Autieri, Filomena Forte +4
We present a systematic derivation of a minimal five-band tight-binding model for the description of the electronic structure of the recently discovered quasi one-dimensional super…
Optimizing the tight-binding parametrization of the quasi-one-dimensional superconductor K2Cr3As3
Giuseppe Cuono, Carmine Autieri, Filomena Forte +5
We study the tight-binding dispersion of the recently discovered superconductor K2Cr3As3, obtained from Wannier projection of Density Functional Theory (DFT) results. In order to e…
Low energy bands and transport properties of chromium arsenide
Carmine Autieri, Giuseppe Cuono, Filomena Forte +1
We apply a method that combines the tight-binding approximation and the Lowdin down-folding procedure to evaluate the electronic band structure of the newly discovered pressure-ind…
