Tetrahedral Core in a Sea of Competing Magnetic Phases in Graphene
Maxime Lucas, Arnaud Ralko, Andreas Honecker +1
We demonstrate the emergence of a robust tetrahedral magnetic ground state in monolayer graphene doped to the van Hove singularity (vHS). This noncoplanar, gapped spin configuratio…
ESR modes in a Strong-Leg Ladder in the Tomonaga-Luttinger Liquid Phase
M. Ozerov, M. Maksymenko, J. Wosnitza +6
Magnetic excitations in the strong-leg quantum spin ladder compound (CHN)CuBr (known as DIMPY) in the field-induced Tomonaga-Luttinger spin liquid phase are stud…
Quantum disordered ground state for hard-core bosons on the frustrated square lattice
A. Kalz, A. Honecker, S. Fuchs +1
We investigate the phase diagram of hard-core bosons on a square lattice with competing interactions. The hard-core bosons can be represented also by spin-1/2 operators and the mod…
Magnetic properties of the Hubbard model on kagome stripes
O. Derzhko, M. Maksymenko, J. Richter +2
We consider the one-orbital -site repulsive Hubbard model on two kagome-like chains, both of which yield a completely dispersionless (flat) one-electron band. Using exact many-e…
