Spin excitations and thermodynamics of the t-J model on the honeycomb lattice
A. A. Vladimirov, D. Ihle, N. M. Plakida
We present a spin-rotation-invariant Green-function theory for the dynamic spin susceptibility in the spin-1/2 antiferromagnetic t-J Heisenberg model on the honeycomb lattice. Empl…

Imaging Orbital-selective Quasiparticles in the Hund's Metal State of FeSe
Andrey Kostin, Peter O. Sprau, Andreas Kreisel +6
Strong electronic correlations, emerging from the parent Mott insulator phase, are key to copper-based high temperature superconductivity (HTS). By contrast, the parent phase of ir…
