Dimensional reduction in quantum spin-1/2 system on a 1/7-depleted triangular lattice
Ryo Makuta, Chisa Hotta
We study the magnetism of a quantum spin-1/2 antiferromagnet on a maple-leaf lattice which is obtained by regularly depleting 1/7 of the sites of a triangular lattice. Although the…

Sine-square deformation applied to classical Ising models
Chisa Hotta, Takashi Nakamaniwa, Tota Nakamura
Sine-square deformation (SSD) is a treatment proposed in quantum systems, which spatially modifies a Hamiltonian, gradually decreasing the local energy scale from the center of the…

Perfect flat band with chirality and charge ordering out of strong spin-orbit interaction
Hiroki Nakai, Chisa Hotta
Spin-orbit interaction established itself as a major role player for emergent phenomena in modern condensed matter including a topological insulator, spin liquid and spin-dependent…
