Effect of on-site Coulomb repulsion on phase transitions in exactly solved spin-electron model
Lucia Galisova, Jozef Strecka, Akinori Tanaka +1
A hybrid lattice-statistical model on doubly decorated planar lattices, which have localized Ising spins at their nodal lattice sites and two itinerant electrons at each pair of de…

Magnetic properties of the quantum spin-1/2 XX diamond chain: The Jordan-Wigner approach
Taras Verkholyak, Jozef Strecka, Michal Jascur +1
The Jordan-Wigner transformation is applied to study magnetic properties of the quantum spin-1/2 model on the diamond chain. Generally, the Hamiltonian of this quantum spin sy…
