Description:
Author(s): Frédéric Michaud, Salvatore R. Manmana, and Frédéric Mila Building on the generalization of the exactly dimerized Majumdar-Ghosh ground state to arbitrary spin S for the Heisenberg chain with a three-site term ( S i −1 · S i )( S i · S i +1 )+H.c., we use density-matrix renormalization group simulations and exact diagonalizations to determine the nature of the dimerizat...
