Paraan}, title = {Entanglement and fluctuations in the Majumdar-Ghosh model ground state}, abstract = {The matrix product state representation of the ground state of the Majumdar{\textendash}Ghosh Model (MGM) is used to obtain the reduced density matrix of a block of x spins in a periodic MGM chain. This calculation leads to exact expressions for the entanglement entropy and subsystem fluctuations as a function of block length. We find that the entanglement entropy saturates exponentially to ln 3, even as the subsystem Hilbert space is five-dimensional.}, year = {2016}, pages = {QUICC S1}, month = {4-8 Dec 2016}, organization = {Joint 13th Asia Pacific Physics Conference and 22nd Australian Institute of Physics Congress}, address = {Brisbane, Australia}, }
