Quantum phase transitions about parity breaking in matrix product systems
Quantum phase transitions about parity breaking in matrix product systems
Abstract
According to our scheme to construct quantum phase transitions （QPTs） in spin chain systems with matrix product ground states, we first successfully combine matrix product state （MPS） QPTs with spontaneous symmetry breaking. For a concrete model, we take
