Electronic properties of Fabre charge-transfer salts under various temperature and pressure conditions
A. C. Jacko, H. Feldner, E. Rose +4
Using density functional theory, we determine parameters of tight-binding Hamiltonians for a variety of Fabre charge transfer salts, focusing in particular on the effects of temper…
Spin-liquid versus spiral-order phases in the anisotropic triangular lattice
Luca F. Tocchio, Hélène Feldner, Federico Becca +2
We study the competition between magnetic and spin-liquid phases in the Hubbard model on the anisotropic triangular lattice, which is described by two hopping parameters t and t' i…
Multiferroic FeTeOBr: Alternating spin chains with frustrated interchain interactions
M. Pregelj, H. O. Jeschke, H. Feldner +11
A combination of density functional theory calculations, many-body model considerations, magnetization and electron spin resonance measurements shows that the multiferroic FeTe…
Ferromagnetic frustrated spin systems on the square lattice: a Schwinger boson study
H. Feldner, D. C. Cabra, G. L. Rossini
We study a ferromagnetic Heisenberg spin system on the square lattice, with nearest neighbors interaction J_1 frustrated by second J_2 and third J_3 neighbors antiferromagnetic int…
Dynamical Signatures of Edge-State Magnetism on Graphene Nanoribbons
Hélène Feldner, Zi Yang Meng, Thomas C. Lang +3
We investigate the edge-state magnetism of graphene nanoribbons using projective quantum Monte Carlo simulations and a self-consistent mean-field approximation of the Hubbard model…
Magnetism of Finite Graphene Samples: Mean-Field Theory compared with Exact Diagonalization and Quantum Monte Carlo Simulation
Hélène Feldner, Zi Yang Meng, Andreas Honecker +3
The magnetic properties of graphene on finite geometries are studied using a self-consistent mean-field theory of the Hubbard model. This approach is known to predict ferromagnetic…
