Strongly correlated model of acousticlike plasmons persisting across the phase diagram of cuprate superconductors
Luciano Zinni, Hiroyuki Yamase, Matthias Hepting +2
Layered two-dimensional electron systems exhibit both optical and acousticlike plasmons around the Brillouin-zone center. In the layered cuprate LaSrCuO, resonant i…

Altermagnetic Instabilities from Quantum Geometry
Niclas Heinsdorf
Altermagnets are a newly identified type of collinear anti-ferromagnetism with vanishing net magnetic moment, characterized by lifted Kramers' degeneracy in parts of the Brillouin…
