Comparing quantum fluctuations in the spin- $\frac{1}{2}$ and spin- $1$ XXZ Heisenberg models on square and honeycomb lattices

Masahiro Kadosawa, Masaaki Nakamura, Yukinori Ohta +1

We present a detailed investigation of the XXZ Heisenberg model for spin- $1/2$ and spin- $1$ systems on square and honeycomb lattices. Utilizing the density-matrix renormalization g…

Chern numbers in two-dimensional systems with spiral boundary conditions

Masaaki Nakamura, Shohei Masuda

We discuss methods for calculating Chern numbers of two-dimensional lattice systems using spiral boundary conditions, which sweep all lattice sites in one-dimensional order. Specif…
