Bridging Rokhsar-Kivelson Type and Generic Quantum Phase Transitions via Thermofield Double States
Wen-Tao Xu, Rui-Zhen Huang, Guang-Ming Zhang
The formalism of the Rokhsar-Kivelson (RK) model has been frequently used to study topological phase transitions in 2D in terms of the deformed wavefunctions, which are RK-type wav…
Quantum phase transition between symmetry enriched topological phases in tensor-network states
Lukas Haller, Wen-Tao Xu, Yu-Jie Liu +1
Quantum phase transitions between different topologically ordered phases exhibit rich structures and are generically challenging to study in microscopic lattice models. In this wor…
Complete characterization of non-Abelian topological phase transitions and detection of anyon splitting with projected entangled pair states
Wen-Tao Xu, Jose Garre-Rubio, Norbert Schuch
It is well-known that many topological phase transitions of intrinsic Abelian topological phases are accompanied by condensation and confinement of anyons. However, for non-Abelian…
Characterization of topological phase transitions from a non-Abelian topological state and its Galois conjugate through condensation and confinement order parameters
Wen-Tao Xu, Norbert Schuch
Topological phases exhibit unconventional order that cannot be detected by any local order parameter. In the framework of Projected Entangled Pair States(PEPS), topological order i…
Constructing tensor network wavefunction for a generic two-dimensional quantum phase transition via thermofield double states
Wen-Tao Xu, Guang-Ming Zhang
The most important feature of two-dimensional quantum Rokhsar-Kivelson (RK) type models is that their ground state wavefunction norms can be mapped into the partition functions of…
Non-Hermitian effects of the intrinsic signs in topologically ordered wavefunctions
Qi Zhang, Wen-Tao Xu, Zi-Qi Wang +1
Negative signs in many-body wavefunctions play an important role in quantum mechanics. The ground-state wavefunction of double semion model on a two-dimensional hexagonal lattice c…
Tensor network approach to phase transitions of a non-Abelian topological phase
Wen-Tao Xu, Qi Zhang, Guang-Ming Zhang
The non-abelian topological phase with Fibonacci anyons minimally supports universal quantum computation. In order to investigate the possible phase transitions out of the Fibonacc…
Tricritical point with fractional supersymmetry from a Fibonacci topological state
Wen-Tao Xu, Guang-Ming Zhang
We consider a generic Fibonacci topological wave function on a square lattice, and the norm of this wave function can be mapped into the partition function of two-coupled -s…
Tensor network state approach to quantum topological phase transitions and their criticalities of topologically ordered states
Wen-Tao Xu, Guang-Ming Zhang
We construct a general wave function with the topological order by introducing the gauge degrees of freedom, characterizing both the toric code state and double se…
Enriched classification of parafermionic gapped phases with time reversal symmetry
Wen-Tao Xu, Guang-Ming Zhang
Based on the recently established parafermionic matrix product states, we study the classification of one-dimensional gapped phases of parafermions with the time reversal (TR) symm…
Classifying parafermionic gapped phases using matrix product states
Wen-Tao Xu, Guang-Ming Zhang
In the Fock representation, we construct matrix product states (MPS) for one-dimensional gapped phases for parafermions. From the analysis of irreducibility of MPS…
Matrix product states for topological phases with parafermions
Wen-Tao Xu, Guang-Ming Zhang
In the Fock representation, we propose a framework to construct the generalized matrix product states (MPS) for topological phases with parafermions. Unlike the $…
