Evidence of electronic states driving current-induced insulator-to-metal transition
V. K. Bhartiya, R. Hartmann, F. Forte +16
On demand current-driven insulator-to-metal transition (IMT) is pivotal for the next generation of energy-efficient and scalable microelectronics. IMT is a key phenomenon observed…
Emerging new phases in correlated Mott insulator Ca2RuO4
Giuseppe Cuono, Filomena Forte, Alfonso Romano +1
The Mott insulator Ca2RuO4 is a paradigmatic example among transition metal oxides, where the interplay of charge, spin, orbital, and lattice degrees of freedom leads to competing…
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.…
Mott-Insulator Ca2RuO4 under a static external electric field
Giuseppe Cuono, Carmine Autieri
We have investigated the structural, electronic and magnetic properties of the Mott-insulator Ca2RuO4 under the application of a static external electric field in two regimes: bulk…
Orbital order and ferromagnetism in LaMnO3 doped with Ga
C. Autieri, M. Cuoco, G. Cuono +2
We study from first principles the magnetic, electronic, orbital and structural properties of the LaMnO3 doped with gallium replacing the Mn-site. The gallium doping reduces the Ja…
Sign change of the anomalous Hall effect and the anomalous Nernst effect in Weyl semimetal CeAlSi
Md Shahin Alam, Amar Fakhredine, Mujeeb Ahmed +9
We report the anomalous Hall effect (AHE) and the anomalous Nernst effect (ANE) data for the non-collinear Weyl semimetal CeAlSi. The anomalous Hall conductivity (σ_ij^A) was measu…
Spatially modulated, orbital selective ferromagnetism in LaCoGe
Giuseppe Cuono, Carmine Autieri, Marcin M. Wysokiński
We present density functional theory calculations for low- metallic ferromagnet LaCoGe at ambient and applied pressures. Our investigations reveal that the system…
Tuning interchain ferromagnetic instability in A2Cr3As3 ternary arsenides by chemical pressure and uniaxial strain
Giuseppe Cuono, Filomena Forte, Alfonso Romano +4
We analyze the effects of chemical pressure induced by alkali metal substitution and uniaxial strain on magnetism in the A2Cr3As3 (A = Na, K, Rb, Cs) family of ternary arsenides wi…
Intra-chain collinear magnetism and inter-chain magnetic phases in Cr3As3-K-based materials
Giuseppe Cuono, Filomena Forte, Alfonso Romano +4
We perform a comparative study of the KCr3As3 and the K2Cr3As3 quasi 1D compounds, and show that the strong interplay between the lattice and the spin degrees of freedom promotes a…
