Strongly-coupled hybrid lattice-plasmons in layered cuprates
Ke-Jun Xu, Nathan Giles-Donovan, Stefano Agrestini +11
Metallic systems with delocalized valence electrons host collective charge density oscillations known as plasmons. On the other hand, conventional insulators do not have free elect…
Low energy excitations in A-site ordered SmBaMn2O6
Mirian Garcia Fernandez, Abhishek Nag, Stefano Agrestini +5
The electron in a solid can be considered a bound state of the three independent, fundamental degrees of freedom creating quasi-particles: spinons, carrying the electron spin; plas…
Doping dependence of 2-spinon excitations in the doped 1D cuprate BaCuO
Jiarui Li, Daniel Jost, Ta Tang +12
Recent photoemission experiments on the quasi-one-dimensional Ba-based cuprates suggest that doped holes experience an attractive potential not captured using the simple Hubbard mo…
Orbital inversion and emergent lattice dynamics in infinite layer CaCoO
Daniel Jost, Eder G. Lomeli, Woo Jin Kim +10
The layered cobaltate CaCoO exhibits a unique herringbone-like structure. Serving as a potential prototype for a new class of complex lattice patterns, we study the properties…
