Entanglement in the Ground State of an Isotropic Three-Qubit Transverse XY Chain with Energy Current
-
Abstract
The ground state entanglement in an isotropic three-qubit transverse XY chain with energy current is analysed. A quantum phase transition from a no-energy-current phase to energy-current phase is found when the magnetic field changes. It has also been found that the ground state changes in company with the quantum phase transition.
