Quantum cluster kink and ring frustration

  title={Quantum cluster kink and ring frustration},
  author={Zhen-Yu Zheng and Han-Chuan Kou and Peng Li},
In this paper, we work on the pure and mixed cluster models with periodic boundary condition. The first purpose is to establish the concept of quantum cluster kink. Simple pictures are easily constructed in the pure cluster model. We clarify that there are two types of cluster kinks since there are two types of ground states depending on the cluster length, of which the first type exhibits symmetry breaking order and the second one exhibits string order. Based on the pictures, cluster kink… Expand

Quaternary Jordan-Wigner mapping and topological extended-kink phase in the interacting Kitaev ring
On a ring, a single Jordan-Wigner transformation between the Kitaev model and the spin model suffers redundant degrees of freedom. However, we can establish an exact quaternary Jordan-Wigner mappingExpand
Topological and nematic ordered phases in many-body cluster-Ising models
We present a fully analytically solvable family of models with many-body cluster interaction and Ising interaction. This family exhibits two phases, dubbed cluster and Ising phases, respectively. TheExpand
Scaling of geometric phase versus band structure in cluster-Ising models.
With this study, the scaling behavior of the geometric phase in relation to the topology and low-energy properties of the band structure of the system is quantified. Expand
Statistical mechanics of the Cluster-Ising model
We study a Hamiltonian system describing a three-spin-1/2 clusterlike interaction competing with an Ising-like antiferromagnetic interaction. We compute free energy, spin-correlation functions, andExpand
n-cluster models in a transverse magnetic field
In this paper we analize a family of one dimensional fully analytically solvable models, named the n-cluster models in a transverse magnetic field, in which a many-body cluster interaction competesExpand
Absence of local order in topologically frustrated spin chains
We show that a wide class of spin chains with topological frustration cannot develop any local order. In particular, we consider translational-invariant one-dimensional chains with frustratedExpand
One-dimensional symmetry protected topological phases and their transitions
We present a unified perspective on symmetry protected topological (SPT) phases in one dimension and address the open question of what characterizes their phase transitions. In the first part of thisExpand
Phase transitions of a cluster Ising model.
A cluster Ising model with multispin interactions which can be exactly solved in the framework of free fermions is studied, finding that the ordinary critical point is ν=1, and the critical exponent that describes the scaling behaviors of the order parameter is β=ΔN_w/8. Expand
Ring frustration and factorizable correlation functions of critical spin rings.
This work establishes the concept of nonlocality in a many-body system in the thermodynamic limit by calculating the nonlocal factors embedded in the factorizable correlation function and clearly shows the intriguing difference between the periodic chains with odd and even numbers of lattice sites even in the thermal limit. Expand
Rigorous proof for the nonlocal correlation function in the transverse Ising model with ring frustration.
It is proved that all the low excited energy states forming the gapless kink phase share the same asymptotic correlation function with the ground state, and the thermal correlation function almost remains constant at low temperatures if one assumes a canonical ensemble. Expand
