ProgrammeP.11 -- Poster Date: Friday, 24 November 2017 Time: 10:30 - 11:20 Entanglement entropy in a Spin-boson model and in Ising model with Dzyaloshinskii-Moriya interaction dimerRafael S. dela Rosa, Francis N.C. Paraan National Institute of Physics We study the interaction of spin and boson by calculating the entanglement entropy in the Spin-boson model using different ans\"{a}tze. The entanglement entropy increases exponentially with the displacement parameters of the boson modes. We also study spin-spin interaction by calculating the entanglement entropy of an isolated coupled spin in Ising model with Dzyaloshinskii-Moriya interaction. We show the dependence of the entanglement entropy on the interaction parameter, $D$, of the model. Presenter: Rafael S. dela Rosa |
