Tunable rotons in square lattice antiferromagnets under strong magnetic fields
Yurika Kubo, Susumu Kurihara
Excitation spectra of square lattice Heisenberg antiferromagnets in magnetic fields are investigated by the spin-wave theory. It is pointed out that a rotonlike structure appears i…

Spin Conductivity in Two-Dimensional Non-Collinear Antiferromagnets
Yurika Kubo, Susumu Kurihara
We propose a method to derive the spin current operator for non-collinear Heisenberg antiferromagnets. We show that the spin conductivity calculated by the spectral representation…
