Phase diagram of the spin-1/2 Kitaev-Gamma chain and emergent SU(2) symmetry
Wang Yang, Alberto Nocera, Tarun Tummuru +2
We study the phase diagram of a one-dimensional version of the Kitaev spin-1/2 model with an extra ``-term", using analytical, density matrix renormalization group and exact dia…

Dispersions of Many-Body Bethe strings
Anup Kumar Bera, Jianda Wu, Wang Yang +9
Complex bound states of magnetic excitations, known as Bethe string, were predicted almost a century ago to exist in one-dimensional quantum magnets 1. The dispersions of the strin…

Quantum Critical Dynamics of a Heisenberg-Ising Chain in a Longitudinal Field: Many-Body Strings versus Fractional Excitations
Zhe Wang, M. Schmidt, A. Loidl +11
We report a high-resolution terahertz spectroscopic study of quantum spin dynamics in the antiferromagnetic Heisenberg-Ising spin-chain compound BaCoVO as a function of…
