Graded Projected Entangled-Pair State Representations and An Algorithm for Translationally Invariant Strongly Correlated Electronic Systems on Infinite-Size Lattices in Two Spatial Dimensions
Qian-Qian Shi, Sheng-Hao Li, Jian-Hui Zhao +1
An algorithm to find a graded Projected Entangled-Pair State representation of the ground state wave functions is developed for translationally invariant strongly correlated electr…
Quantum phase transitions and bifurcations: reduced fidelity as a phase transition indicator for quantum lattice many-body systems
Jin-Hua Liu, Qian-Qian Shi, Jian-Hui Zhao +1
We establish an intriguing connection between quantum phase transitions and bifurcations in the reduced fidelity between two different reduced density matrices for quantum lattice…
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 ground state fidelity and quantum phase transitions for the Kitaev model
Jian-Hui Zhao, Huan-Qiang Zhou
The ground state fidelity per lattice site is shown to be able to detect quantum phase transitions for the Kitaev model on the honeycomb lattice, a prototypical example of quantum…
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…
