Symmetry-breaking dynamics of the finite-size Lipkin-Meshkov-Glick model near ground state
Yi Huang, Tongcang Li, Zhang-qi Yin
We study the dynamics of the Lipkin-Meshkov-Glick (LMG) model with finite number of spins. In the thermodynamic limit, the ground state of the LMG model with isotropic Hamiltonian…
