Description
We study the squeezing and pairwise entanglement properties of multi-qubit spin systems, implemented by a two-axis countertwisting Hamiltonian, with and without an external field. We show that the addition of an external field, enforces stronger squeezing and entanglement, and also increases the time duration that these phenomena may be maintained
