Exact momentum-space analysis of small spin-1/2 $J_{1}$ - $J_{2}$ rings

Zimeng Li, Ning Wu

This paper considers an $N$ -site spin-1/2 $J_{1}$ - $J_{2}$ ring with $N = 6$ and $8$ . With the help of a set of exact few-magnon Bloch states, we obtain the block-diagonalized Hamiltonian…

Exact solution of the two-magnon problem in the $k = - I ¨ /2$ sector of a finite-size anisotropic spin-1/2 frustrated ferromagnetic chain

Zimeng Li, Ning Wu

The two-magnon problem in the $k = - I ¨ /2$ sector of a \emph{finite-size} spin-1/2 chain with ferromagnetic nearest-neighbor (NN) interaction $(J_{1} > 0)$ and antiferromagnetic next-near…

Collective charging of an organic quantum battery

Jiawei Li, Ning Wu

We study the collective charging of a quantum battery (QB) consisting of a one-dimensional molecular aggregate and a coupled single-mode cavity, to which we refer as an ``organic q…
