Study of Staggered Magnetization in the Spin- Square-Lattice Heisenberg Model Using Spiral Boundary Conditions
Masahiro Kadosawa, Masaaki Nakamura, Yukinori Ohta +1
We propose an efficient numerical method to obtain local order parameter in two-dimensional systems using spiral boundary conditions. As a benchmark, we first estimate the magnitud…
Electronic polarization in non-Bloch band theory
Shohei Masuda, Masaaki Nakamura
Hermitian topological materials are characterized by the nontrivial relation between topological numbers and edge modes, i.e. the bulk-boundary correspondence. In non-Hermitian sys…
One-dimensional projection of two-dimensional systems using spiral boundary conditions
Masahiro Kadosawa, Masaaki Nakamura, Yukinori Ohta +1
We introduce spiral boundary conditions (SBCs) as a useful tool for handling the shape of finite-size periodic clusters. Using SBCs, a lattice model for more than two dimensions ca…
