چکیده
Convergent expansions of the wavefunctions for the ground state and low-lying excited states of quantum transverse Ising systems are obtained. These expansions are employed to prove that the dispersion relation for a single quasi-particle has a convergent expansion.

متن کاملSpin - dependent charge of quasiparticle clusters in
A state with 2 electons has a charge of 1/2. The states of 3 electrons have quasiparticle charge of 4/11 and 5/13; the one with 5 electrons have quasiparticle charges 4/13 and 6/17. The state with 7 electrons exhibits quasiparticle charges of 5/17 and 12/17. When spin is reversed, the charge of three particle state changes from 4/11 to 7/11. These predicted results agree with the recent experim...
متن کاملSingle hole dynamics in dimerized spin liquids
The dynamics of a single hole in quantum antiferromagnets is influenced by magnetic fluctuations. In the present work we consider two situations. The first one corresponds to a single hole in the two leg t − J spin ladder. In this case the wave function renormalization is relatively small and the quasiparticle residue of the S = 1/2 state remains close to unity. However at large t/J there are h...
متن کاملA Perturbative Approach to Spectrum and Correlation Functions of the Chiral Potts Model
The massive high-temperature phase of the chiral Potts quantum chain is studied using perturbative methods. For the Z 3-chain we present high-temperature expansions for the groundstate energy and the dispersion relations of the two single-particle states as well as two-particle states at general values of the parameters. We also present a perturbative argument showing that a large class of mass...

The formation of bound states of holes in an antiferromagnetic spin-1/2 background is studied using numerical techniques applied to the t− J Hamiltonian on clusters with up to 26 sites. An analysis of the binding energy as a function of cluster size suggests that a two hole bound state is formed for couplings larger than a “critical” value J/t]c. The symmetry of the bound state is dx2−y2 . We a...
