Magnetoelectric flat band induced by a charge density wave in monolayer CrSe
Pablo Savino, M. del Carmen Fuente Santiago, Jan Phillips +4
We investigate the electronic and magnetic properties of the polar charge-density-wave (CDW) phase of CrSe using ab initio calculations. The CDW introd…
Contrasting Spin Excitations in Octahedral and Square-Planar n=8 Ruddlesden-Popper Nickelates
K. Scott, H. LaBollita, G. A. Pan +15
The discovery of superconductivity in reduced square-planar nickelates marked a major advance in identifying structural and electronic analogs to the high- cuprates. The more…
Flat band driven competing charge and spin instabilities in the altermagnet CrSb
A. Korshunov, M. Alkorta, C. -Y. Lim +8
The confinement of electronic wavefunctions in momentum space can give rise to flat electronic bands, where the quenching of kinetic energy enhances the density of states and ampli…
Charge disproportionation and nano phase separation in SrNiO
H. Guo, Z. W. Li, C. F. Chang +16
We have successfully grown centimeter-sized layered SrNiO single crystals under high oxygen pressures of 120 bar by the floating zone technique. This enabled us to perform n…
