Sine-square deformation of free fermion systems in one and higher dimensions
Isao Maruyama, Hosho Katsura, Toshiya Hikihara
We study free fermion systems with the sine-square deformation (SSD), in which the energy scale of local Hamiltonians is modified according to the scaling function f(x)=sin^2[π(x-1…
Edge magnetism of Heisenberg model on honeycomb lattice
Wen-Min Huang, Yen-Chen Lee, Toshiya Hikihara +1
In our previous study, a single-branch of ferromagnetic magnon with linear dispersion is shown to exist near the (uncompensated) zigzag edge for Heisenberg model on honeycomb latti…
NMR relaxation rate in the field-induced octupolar liquid phase of spin-1/2 J1-J2 frustrated chains
Masahiro Sato, Toshiya Hikihara, Tsutomu Momoi
In the spin-1/2 frustrated chain with nearest-neighbor ferromagnetic exchange J1 and next-nearest-neighbor antiferromagnetic exchange J2 under magnetic field, magnetic multipolar-l…
