Superconfined Antiferromagnons on the Two-Dimensional Penrose Lattice
Takashi Inoue, Shoji Yamamoto
We find novel confined states in the spin- nearest-neighbor antiferromagnetic Heisenberg model on the two-dimensional Penrose lattice. Linear spin waves have massively degenerat…
Raman Characterization of Two-Dimensional Quasiperiodic Antiferromagnets on Various Lattices: Spin-Orbit Mechanism
Takashi Inoue, Shoji Yamamoto
We study first-order (single-magnon) inelastic light scatterings in spin- two-dimensional quasiperiodic antiferromagnets in comparison with those emergent on periodic…
Breakdown of the conventional spin-wave dynamics and its double-constraint modification in the spin- triangular-prism Heisenberg antiferromagnet
Shoji Yamamoto, Jun Ohara
Spontaneous magnon decays in an Heisenberg antiferromagnet on the equilateral triangular prism are investigated in terms of modified magnon Green's functions. In on…
Magnon Confinement on the Two-Dimensional Penrose Lattice: Perpendicular-Space Analysis of the Dynamic Structure Factor
Shoji Yamamoto, Takashi Inoue
Employing the spin-wave formalism within and beyond the harmonic-oscillator approximation, we study the dynamic structure factors of spin- nearest-neighbor quantum Hei…
