Quantum fidelity approach to detecting quantum phases: revisiting the bond alternating Ising chain
Hai Tao Wang, Sam Young Cho, Murray T. Batchelor
We demonstrate the quantum fidelity approach for exploring and mapping out quantum phases. As a simple model exhibiting a number of distinct quantum phases, we consider the alterna…
Long-range string orders and topological quantum phase transitions in the one-dimensional quantum compass model
Hai Tao Wang, Sam Young Cho
In order to investigate the quantum phase transition in the one-dimensional quantum compass model, we numerically calculate non-local string correlations, entanglement entropy, and…
Bond-Alternation-Induced Topological Quantum Gaussian Transition and Topological Quantum Crossover in Ising Chains with the Dzyaloshinskii-Moriya Interaction
Hai Tao Wang, Sam Young Cho
Non-local orders, entanglement entropy, and quantum fidelity are investigated in an infinite-size bond-alternating Ising chain with the Dzyaloshinskii-Moriya interaction by employi…
Topological quantum phase transition in bond-alternating spin-1/2 Heisenberg chains
Hai Tao Wang, Bo Li, Sam Young Cho
We investigate string correlations in an infinite-size spin-1/2 bond-alternating Heisenberg chain. By employing the infinite matrix product state representation with the infinite t…
