Ferromagnetic spin-orbital liquid of dipolar fermions in zigzag lattices
G. Sun, A. K. Kolezhuk, L. Santos +1
Two-component dipolar fermions in zigzag optical lattices allow for the engineering of spin-orbital models. We show that dipolar lattice fermions permit the exploration of a regime…
Current fidelity susceptibility and conductivity in one-dimensional lattice models with open and periodic boundary conditions
S. Greschner, A. K. Kolezhuk, T. Vekua
We study, both numerically and analytically, the finite size scaling of the fidelity susceptibility χ_{J} with respect to the charge or spin current in one-dimensional lattice mode…
Double zigzag spin chain in strong magnetic field close to saturation
I. T. Shyiko, I. P. McCulloch, J. V. Gumenjuk-Sichevska +1
We study the ground state phase diagram of a frustrated spin tube in a strong external magnetic field. This model can be viewed as two coupled zigzag spin chains, or as a two-leg s…
Dynamics and relaxation in spin nematics
V. G. Bar'yakhtar, V. I. Butrim, A. K. Kolezhuk +1
We study dynamics and relaxation of elementary excitations (magnons) in the spin nematic (quadrupole ordered) phase of S=1 magnets. We develop a general phenomenological theory of…
