简介: |
We discuss an information-theoretic approach to quantum phase and phase
transitions, by exploring a relationship between the topological entanglement entropy
and the irreducible many-body correlations. This relationship leads to a new type of
topological entanglement entropy, which can be used to probe the symmetrybreaking
properties hidden in the exact ground states of the symmetry-breaking
orders. To use this new topological entanglement entropy for probing a quantum
phase transition with symmetry-breaking, there is no need to know the symmetry or
the symmetry-breaking order parameter.
