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

Kazuo Hida

The ground-state phases of mixed diamond chains with ( $S, I ¨ ^{(1)}, I ¨ ^{(2)}) = (1/2, 1/2, 1)$ , where $S$ is the magnitude of vertex spins, and $I ¨ ^{(1)}$ and $I ¨ ^{(2)}$ are those of a…

A causality-based divide-and-conquer algorithm for nonequilibrium Green's function calculations with quantics tensor trains

Ken Inayoshi, Maksymilian Åroda, Anna Kauch +2

We propose a causality-based divide-and-conquer algorithm for nonequilibrium Green's function calculations with quantics tensor trains. This algorithm enables stable and efficient…
