Ground-State Phase Diagram of (1/2,1/2,1) Mixed Diamond Chains with Single-Site Anisotropy

Kazuo Hida

Anisotropy inversion stabilizes Ising-like Néel order for easy-plane D>0 and XY-like liquid for easy-axis D<0 in (1/2,1/2,1) diamond chains.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

A region with anisotropy inversion is found where the Ising-like Néel phase is realized for the easy-plane anisotropy D >0 and the XY-like Tomonaga-Luttinger liquid phase is realized for the easy-axis anisotropy D <0 on the S=1 sites.

C2weakest assumption

That finite-size exact diagonalization and DMRG calculations, together with limiting-case approximations, faithfully capture the infinite-chain thermodynamic limit without uncontrolled finite-size or truncation errors.

C3one line summary

Numerical study of (1/2,1/2,1) mixed diamond chains reveals Néel, Tomonaga-Luttinger liquid, and ferrimagnetic phases plus an anisotropy inversion where easy-plane D>0 yields Ising Néel order while easy-axis D<0 yields XY-like liquid.
