Macroscopic entanglement jumps in model spin systems
Indrani Bose, Emily Chattopadhyay
In this paper, we consider some frustrated spin models for which the ground states are known exactly. The concurrence, a measure of the amount of entanglement can be calculated exa…

Magnetization plateaux in a generalised ladder model
Emily Chattopadhyay, Indrani Bose
A spin-1/2 antiferromagnetic(AFM) generalised ladder model is constructed which consists of four-spin plaquettes, coupled through weaker exchange interactions, to two-spin rungs. I…
