Gapless symmetry-protected topological phase of quantum antiferromagnets on anisotropic triangular strip

Yuichiro Hidaka, Shunsuke C. Furuya, Atsushi Ueda +1

We study a three-leg spin-1/2 ladder with geometrically frustrated interleg interactions. We call this model an anisotropic triangular-strip (ATS) model. We numerically and field-t…

Tensor Network Renormalization Study on the Crossover in Classical Heisenberg and $R P^{2}$ Models in Two Dimensions

Atsushi Ueda, Masaki Oshikawa

We study the classical two-dimensional $R P^{2}$ and Heisenberg models, using the Tensor-Network Renormalization (TNR) method. The determination of the phase diagram of these…
