A Kitaev material on the triangular lattice: The case of NaRuO
Aleksandar Razpopov, David A. S. Kaib, Steffen Backes +5
Motivated by recent reports of a quantum disordered ground state in the triangular lattice compound NaRuO, we derive a magnetic model for this system by means…
Improved effective vertices in the multi-orbital Two-Particle Self-Consistent method from Dynamical Mean-Field Theory
Karim Zantout, Steffen Backes, Aleksandar Razpopov +2
In this work we present a multi-orbital form of the Two-Particle Self-Consistent approach (TPSC), here the effective local and static irreducible interaction vertices are determine…
Combined experimental and theoretical study of hydrostatic (He-gas) pressure effects in -RuCl
B. Wolf, D. A. S. Kaib, A. Razpopov +13
We report a detailed experimental and theoretical study on the effect of hydrostatic pressure on the structural and magnetic aspects of the layered honeycomb antiferromagent -Ru…
Microscopic origin of magnetism in monolayer transition metal dihalides
Kira Riedl, Danila Amoroso, Steffen Backes +7
Motivated by the recent wealth of exotic magnetic phases emerging in two-dimensional frustrated lattices, we investigate the origin of possible magnetism in the monolayer family of…
Multi-Center Magnon Excitations Open the Entire Brillouin Zone to Terahertz Magnetometry of Quantum Magnets
Tobias Biesner, Seulki Roh, Aleksandar Razpopov +14
Due to the small photon momentum, optical spectroscopy commonly probes magnetic excitations only at the center of the Brillouin zone; however, there are ways to override this restr…
Electronic and magnetic properties of the RuX (X=Cl, Br, I) family: Two siblings -- and a cousin?
David A. S. Kaib, Kira Riedl, Aleksandar Razpopov +4
Motivated by recent reports of metallic behavior in the recently synthesized RuI, in contrast to the Mott-insulating nature of the actively discussed -RuCl, as well as R…
