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…
