Vectorial Imaging of the Photodissociation of 2-Bromobutane Oriented via Hexapolar State Selection
Masaaki Nakamura, Po-Yu Tsai, Shiun-Jr Yang +6
Molecular orientation techniques are becoming available in the study of elementary chemical processes, in order to highlight those structural and dynamical properties that would be…
Phase diagram of the Kitaev-Heisenberg model using various finite-size clusters
Masahiro Kadosawa, Masaaki Nakamura, Yukinori Ohta +1
We estimate phase boundaries of four ordered and two spin-liquid phases for the spin- Kitaev-Heisenberg (KH) model using four kinds of relatively-small clusters, based…
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…
Relationship between the Electronic Polarization and the Winding Number in Non-Hermitian Systems
Shohei Masuda, Masaaki Nakamura
We discuss an extension of the Resta's electronic polarization to non-Hermitian systems with periodic boundary conditions. We introduce the ``electronic polarization'' as an expect…
