Kondo-Heisenberg toy models: Comparison of exact results and spin wave expansion
M. Frakulla, J. Strockoz, D. S. Antonenko +1
In this paper we study a class of exactly solvable Kondo-Heisenberg toy models in one dimension, with the goal of comparing the exact low-energy excitations of the ferromagnetic gr…
Canonical strong coupling spin wave expansion of Kondo lattice magnets. I. Effective Hamiltonian via canonical transformation
J. Strockoz, M. Frakulla, D. Antonenko +1
This paper develops a systematic strong coupling spin wave expansion of itinerant Kondo lattice magnets, magnets in which local moment spins are Kondo coupled to itinerant charge d…
Flat band physics in the charge-density wave state of -TaS
Amir Dalal, Jonathan Ruhman, Jörn W. F. Venderbos
1-TaS is the only insulating transition-metal dichalcogenide (TMD) with an odd number of electrons per unit cell. This insulating state is non-magnetic, making it a potentia…
Mirror Chern Bands and Weyl Nodal Loops in Altermagnets
Daniil S. Antonenko, Rafael M. Fernandes, Jorn W. F. Venderbos
The electronic spectra of altermagnets are a fertile ground for nontrivial topology due to the unique interplay between time-reversal and crystalline symmetries. This is reflected…
