Zero-temperature study of a tetrameric spin-$1/2$ chain in a transverse magnetic field

J. Vahedi, M. Shabani Arbousara, S. Mahdavifar

We consider an alternating Heisenberg spin-$1/2$ antiferromagnetic-ferromagnetic ($AF-F$) chain with the space modulated dominant antiferromagnetic exchange and anisotropic ferroma…
