Operator content of the four-state Potts quantum chain with Z3-boundary conditions

Abstract

The four-state Potts quantum chain with a toroidal boundary condition leaving a global Z 3 symmetry of the Hamiltonian is investigated. At the critical point, the infinite system shows SU(2) Kac-Moody symmetry. The conjectured operator content is confirmed by numerical finite-size calculations.

Operator content of the Ashkin-Teller quantum chain, superconformal and Zamolodchikov-Fateev invariance. I. Free boundary conditions

Michael Baake, G von Gehlen, V. Rittenberg

Based on numerical analysis, the authors conjecture the operator content of the finite-size limit of the spectra of the Ashkin-Teller model with free boundary conditions. The same operator content is obtained from a Hamiltonian with a four-fermion interaction and a U(1) Kac-Moody Sugawara structure. For some special values of the coupling constant the model exhibits N=2 superconformal and Zamolodchikov-Fateev invariance. The operator content in these cases is expressed in terms of irreducible representations of the corresponding algebras.

The spin-S XXZ quantum chain with general toroidal boundary conditions

Francisco Castilho Alcaraz, Marcio Jose Martins

The authors derive the operator content of the spin-S XXZ quantum chain with generalised toroidal boundary conditions compatible with the U(1) symmetry of the model. These results are derived by solving numerically the associated Bethe ansatz equations for finite chains and exploring the consequences of the conformal invariance of the infinite system. They also show that, as in the spin-1/2 case, the conformal anomaly and dimensions of general extended SU(2) algebras can be obtained from these spin-S chains by choosing properly the coupling constant and the boundary condition.

Toroidal boundary conditions in n-state quantum chains

P. Chaselon

The author considers one-dimensional n-state quantum chains having as symmetry an Abelian group A of order n (generalised Ising chain). These Hamiltonians depend on 2(n-1) coupling constants. For special values of the coupling constants the symmetry of the quantum chains is larger than A corresponding to a (in general non-Abelian) group G with m elements (m)n). For each element of G he finds explicitly a boundary condition which leaves the Hamiltonian translationally invariant. This problem is relevant in finite-size scaling studies at the critical point of a second-order phase transition.

'Duality twisted' boundary conditions in n-state Potts models

Gunter Markus Schutz

The author discusses a new class of toroidal boundary conditions for one-dimensional quantum Hamiltonians with S n symmetry which are related to two-dimensional n-state Potts models in the extreme anisotropic Hamiltonian limit. At their self-dual point (a point where a second-order phase transition occurs for n=2, 3, 4) the duality transformation is shown to be an additional symmetry giving rise to a new class of 'duality twisted' toroidal boundary conditions. The corresponding Hamiltonians are given in terms of generators of the periodic Temperley-Lieb algebra with an odd number of generators. The author discusses as an example the critical Ising model. Here the complete spectrum for the new boundary conditions can be obtained from a projection mechanism in the spin-1/2 XXZ Heisenberg chain.

Emergence of Kac-Moody symmetry in critical quantum spin chains

Ruoshui Wang, Yijian Zou, Guifré Vidal

Given a critical quantum spin chain with a microscopic Lie group symmetry, corresponding, e.g., to $U(1)$ or $SU(2)$ spin isotropy, we numerically investigate the emergence of Kac-Moody symmetry at low energies and long distances. In that regime, one such critical quantum spin chain is described by a conformal field theory where the usual Virasoro algebra associated with conformal invariance is augmented with a Kac-Moody algebra associated with conserved currents. Specifically, we first propose a method to construct lattice operators corresponding to the Kac-Moody generators. We then numerically show that, when projected onto low-energy states of the quantum spin chain, these operators indeed approximately fulfill the Kac-Moody algebra. The lattice version of the Kac-Moody generators allows us to compute the so-called level constant and to organize the low-energy eigenstates of the lattice Hamiltonian into Kac-Moody towers. We illustrate the proposal with the XXZ model and the Heisenberg model with a next-to-nearest-neighbor coupling.

Operator content of the Ising model with three-spin coupling

T. Wittlich

The Ising quantum-chain with staggered three-spin coupling is studied for free and toroidal boundary conditions. The operator content of the finite-size limit of the spectra is conjectured. It is found to be related to the operator content of the Ashkin-Teller model (1943).
