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…
Exchange relaxation as the mechanism of ultrafast spin reorientation in two-sublattice ferrimagnets
V. G. Baryakhtar, V. I. Butrim, B. A. Ivanov
In the exchange approximation, an exact solution is obtained for the sublattice magnetizations evolution in a two-sublattice ferrimagnet. Nonlinear regimes of spin dynamics are fou…
Periods of second kind differentials of (n,s)-curves
J. C. Eilbeck, K. Eilers, V. Z. Enolski
For elliptic curves, expressions for the periods of elliptic integrals of the second kind in terms of theta-constants, have been known since the middle of the 19th century. In this…
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…
Resonant state selection in synthetic ferrimagnets
B. C. Koop, Yu. I. Dzhezherya, K. Demishev +3
Resonant activation of a synthetic antiferromagnet (SAF) is known to result in a dynamic running state, where the SAF's symmetric spin-flop pair continuously rotates between the tw…
Vortex ground state for small arrays of magnetic particles with dipole coupling
S. A. Dzian, A. Yu. Galkin, B. A. Ivanov +2
We show that a magnetic vortex is the ground state of an array of magnetic particles shaped as a hexagonal fragment of a triangular lattice, even for an small number of particles i…
