Groundstate fidelity phase diagram of the fully anisotropic two-leg spin-½ XXZ ladder by Sheng-Hao Li, Qian-Qian Shi, Murray T Batchelor, Huan-Qiang Zhou

“…The fully anisotropic two-leg spin- $\tfrac{1}{2}$ XXZ ladder model is studied in terms of an algorithm based on the tensor network (TN) representation of quantum many-body states as an adaptation of projected entangled pair states to the geometry of translationally invariant infinite-size quantum spin ladders. …”

Fate of spinons in spontaneously dimerized spin-(1)/(2) ladders by Allen, D, Essler, F, Nersesyan, A

“…We study a weakly coupled, frustrated two-leg spin-1/2 Heisenberg ladder. For vanishing coupling between the chains, elementary excitations are deconfined, gapless spin-1/2 objects called spinons. …”

Quantum-critical spin dynamics in a Tomonaga-Luttinger liquid studied with muon-spin relaxation by Möller, J, Lancaster, T, Blundell, S, Pratt, F, Baker, P, Xiao, F, Williams, R, Hayes, W, Turnbull, M, Landee, C

“…Our model system is the strong-leg spin ladder bis(2,3-dimethylpyridinium) tetrabromocuprate (DIMPY). …”

Spin dynamics of coupled spin ladders near quantum criticality in Ba2CuTeO6 by Macdougal, D, Gibbs, A, Ying, T, Wessel, S, Walker, H, Voneshen, D, Mila, F, Takagi, H, Coldea, R

“…We report inelastic neutron scattering measurements of the magnetic excitations in Ba2CuTeO6, proposed by ab initio calculations to magnetically realize weakly coupled antiferromagnetic two-leg spin-1/2 ladders. Isolated ladders are expected to have a singlet ground state protected by a spin gap. …”

Topological Doping and Superconductivity in Cuprates: An Experimental Perspective by John M. Tranquada

“…In the case of cuprates, where the charge stripes have the character of a hole-doped two-leg spin ladder, with corresponding pairing correlations, anti-phase Josephson coupling across the spin stripes can lead to a pair-density-wave order in which the broken translation symmetry of the superconducting wave function is accommodated by pairs with finite momentum. …”

Intrinsic translational symmetry breaking in a doped Mott insulator by Zhu, Zheng, Sheng, D. N., Weng, Zheng-Yu

“…A central issue of Mott physics, with symmetries being fully retained in the spin background, concerns the charge excitation. In a two-leg spin ladder with a spin gap, an injected hole can exhibit either a Bloch wave or a density wave by tuning the ladder anisotropy through a “quantum critical point” (QCP). …”

Strange correlations in spin-1 Heisenberg antiferromagnets by Wierschem, Keola, Sengupta, Pinaki

“…After finding the expected long-range behavior in these two symmetry conserving phases, we go on to verify the topological nature of two-leg and three-leg spin-1 Heisenberg antiferromagnetic ladders. This demonstrates the power of the strange correlator in distinguishing between trivial and nontrivial symmetry protected topological phases.…”

Finite temperature dynamical structure factors of low dimensional strongly correlated systems by Goetze, W, Wolf Goetze

“…We determine the dynamical structure factors of two gapped correlated electron systems, namely the Ising model in a strong transverse field and the two-leg spin-1/2 Heisenberg ladder in the limit of strong rung coupling. …”

Muon-spin relaxation and its application in the study of molecular quantum magnets by Möller, JS

“…I also describe musr measurements on the strong-leg spin ladder DIMPY and on the molecular nanomagnets Cr$_8$Cd and Cr$_8$Mn which highlight some of the remaining challenges for longitudinal-field musr experiments.…”

Neutron scattering studies of low-dimensional quantum magnets by Macdougal, D

“…The first system considered is Ba₂CuTeO₆, proposed to realise weakly-coupled antiferromagnetic two-leg spin-1/2 ladders. Ba₂CuTeO₆ orders magnetically, but with a small Neel temperature relative to the exchange strength, suggesting that the interladder couplings are only just able to stabilise magnetic order and placing Ba₂CuTeO₆ close in parameter space to the critical point separating the singlet phase and Neel order. …”
