摘要
The spin-1/2XX chain with three-spin and uniform long-range interactions among the z components of the spins is investigated. Using the Jordan-Wigner transformation, the thermodynamic quantities and spin transports of the model are evaluated exactly. The phase diagram together with the key parameters characterizing quantum phase transitions is presented.
