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 Cu $_{2}$ Cl(OH) $_{3}$ 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 Cu $_{2}$ Cl(OH) $_{3}$ , a material realization of quantum sawtooth chains with weak interchain couplings, in continuous and pulsed ma…

Origin of the non-Fermi-liquid behavior in CeRh2As2

P. Khanenko, D. Hafner, K. Semeniuk +11

Unconventional superconductivity in heavy-fermion systems appears often near magnetic quantum critical points (QCPs). This seems to be the case also for CeRh2As2 (Tc $\approx$ 0.31…

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…
