Persistent Haldane Phase in Carbon Tetris Chains
Anas Abdelwahab, Christoph Karrasch, Roman Rausch
We introduce the concept of tetris chains, which are linear arrays of 4-site molecules that differ by their intermolecular hopping geometry. We investigate the fermionic symmetry-p…
Atacamite CuCl(OH) in High Magnetic Fields: Quantum Criticality and Dimensional Reduction of a Sawtooth-Chain Compound
L. Heinze, T. Kotte, R. Rausch +13
We report an extensive high-field study of atacamite CuCl(OH), a material realization of quantum sawtooth chains with weak interchain couplings, in continuous and pulsed ma…
Density matrix renormalization group study of the interacting Kitaev chain with quasi-periodic disorder
K. S. C. Decker, C. Karrasch
We document the ground state phase diagram of the one-dimensional Kitaev chain with quasi-periodic disorder in the presence of two-body interactions. Our data was obtained for syst…
Noncollinear phase of the antiferromagnetic sawtooth chain
R. Rausch, C. Karrasch
The antiferromagnetic sawtooth chain is a prototypical example of a frustrated spin system with vertex-sharing triangles, giving rise to complex quantum states. Depending on the in…
