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…
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…
Singularities in fidelity surfaces for quantum phase transitions: a geometric perspective
Huan-Qiang Zhou, Jian-Hui Zhao, Hong-Lei Wang +1
The fidelity per site between two ground states of a quantum lattice system corresponding to different values of the control parameter defines a surface embedded in a Euclidean spa…
Fidelity approach to quantum phase transitions: finite size scaling for quantum Ising model in a transverse field
Huan-Qiang Zhou, Jian-Hui Zhao, Bo Li
We analyze the scaling parameter, extracted from the fidelity for two different ground states, for the one-dimensional quantum Ising model in a transverse field near the critical p…
