Ground state properties and exact thermodynamics of a 2-leg anisotropic spin ladder system
Sk Saniur Rahaman, Shaon Sahoo, Manoranjan Kumar
We study a frustrated two-leg spin ladder with alternate isotropic Heisenberg and Ising rung exchange interactions, whereas, interactions along legs and diagonals are Ising-type. A…
