Nontrivial three-sublattice magnetization in the easy-axis spin-1/2 XXZ antiferromagnet on the triangular lattice
Masahiro Kadosawa, Masaaki Nakamura, Yukinori Ohta +1
We investigate the ground-state magnetic structure of the spin- XXZ antiferromagnet on the triangular lattice in the easy-axis regime using the density-matrix renormalization…
Lieb-Schultz-Mattis-Type and Laughlin-Type Argument for the Quantum Hall Effect in Lattice Fermions with Spiral Boundary Conditions
Masaaki Nakamura, Masanori Yamanaka
We derive the condition for the occurrence of the integer quantum Hall effect in two-dimensional lattice systems with interactions, expressed as , where , …
Comparing quantum fluctuations in the spin- and spin- 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- and spin- 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…
