DOI: 10.1021/acs.chemmater.2c02939
Abstract: Ba2CuTeO6 has attracted significant attention as it contains a two-leg spin ladder of Cu2+ cations that lies in close proximity to a quantum critical point. Recently, Ba2CuTeO6 has been shown to accommodate chemical substitutions, which… read more here.

Abstract: The $S=1/2$ spin ladder compound (C$_5$H$_{12}$N)$_2$CuBr$_4$ (BPCB) is studied by means of high-resolution inelastic neutron scattering. In agreement with previous studies we find a band of triplet excitations with a spin gap of $\sim0.8$~meV and… read more here.

DOI: 10.1103/physrevb.101.195121
Abstract: Chiral Haldane phases are examples of one-dimensional topological states of matter which are protected by projective SU($N$) group (or its subgroup $\mathbb{Z}_N \times \mathbb{Z}_N$) with $N>2$. The unique feature of these symmetry protected topological (SPT)… read more here.

DOI: 10.1103/physrevb.95.184430
Abstract: We report on zero-field muon spin rotation, electron-spin resonance, and polarized Raman scattering measurements of the coupled quantum spin ladder ${\mathrm{Ba}}_{2}{\mathrm{CuTeO}}_{6}$. Zero-field muon spin rotation and electron-spin resonance probes disclose a successive crossover from a… read more here.

DOI: 10.1103/physrevb.96.220405
Abstract: It has recently been found that bosonic excitations of ordered media, such as phonons or spinons, can exhibit topologically nontrivial band structures. Of particular interest are magnon and triplon excitations in quantum magnets, as they… read more here.

DOI: 10.1103/physreve.106.044120
Abstract: We introduce an integrable spin ladder model and study its exact solution, correlation functions, and entanglement properties. The model supports two particle types (corresponding to the even and odd sublattices), such that the scattering phases… read more here.
