Paraan}, title = {Block entanglement in the ground state of the Majumdar-Ghosh model}, abstract = {We use matrix product state representations and transfer matrix methods to calculate the reduced density matrix of a block of spins in the ground state of the Majumdar-Ghosh spin chain. The full entanglement spectrum is obtained and the von Neumann entanglement entropy is expressed as a function of block length. We found that the von Neumann entropy increases exponentially fast as the length of the block increases and has a saturation value of Smax = ln 3.}, year = {2016}, booktitle = {Proceedings of the 34th Samahang Pisika ng Pilipinas Physics Congress}, pages = {SPP-2016-PB-22}, month = {18{\textendash}21 Aug 2016}, address = {University of the Philippines Visayas, Iloilo City}, url = {https://proceedings.spp-online.org/article/view/SPP-2016-PB-22}, }
