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…

Non-local correlations in the Haldane phase for an XXZ spin-1 chain: A perspective from infinite matrix product state representation

Yao Heng Su, Sam Young Cho, Bo Li +2

String correlations are investigated in an infinite-size XXZ spin-1 chain. By using the infinite matrix product state representation, we calculate a long-range string order. In the…

Ground-State Fidelity and Kosterlitz-Thouless Phase Transition for Spin 1/2 Heisenberg Chain with Next-to-the-Nearest-Neighbor Interaction

Hong-Lei Wang, Ai-Min Chen, Bo Li +1

The Kosterlitz-Thouless transition for the spin 1/2 Heisenberg chain with the next-to-the-nearest-neighbor interaction is investigated in the context of an infinite matrix product…

Ground state fidelity in bond-alternative Ising chains with Dzyaloshinskii-Moriya interactions

Bo Li, Sam Young Cho, Hong-Lei Wang +1

A systematic analysis is performed for quantum phase transitions in a bond-alternative one-dimensional Ising model with a Dzyaloshinskii-Moriya (DM) interaction by using the fideli…

Kosterlitz-Thouless Phase Transition and Ground State Fidelity: a Novel Perspective from Matrix Product States

Hong-Lei Wang, Jian-Hui Zhao, Bo Li +1

The Kosterlitz-Thouless transition is studied from the representation of the systems's ground state wave functions in terms of Matrix Product States for a quantum system on an infi…

Spontaneous symmetry breaking and bifurcations in ground state fidelity for quantum lattice systems

Jian-Hui Zhao, Hong-Lei Wang, Bo Li +1

Spontaneous symmetry breaking occurs in a system when its Hamiltonian possesses a certain symmetry, whereas the ground state wave functions do not preserve it. This provides such a…
