Quasi-bound states of two magnons in the spin-1/2 XXZ chain

Y Morita M Kohmoto T Koma

JOURNAL OF STATISTICAL PHYSICS 88(3-4) 745-780 1997年8月

We study two-magnon Bethe states in the spin-1/2 XXZ chain. The string hypothesis assumes that complex rapidities of the bound states take special forms. It is known, however, that there exist ''non-string states,'' which substantially disagrees w...

Mutual-exclusion statistics in exactly solvable models in one and higher dimensions at low temperatures

Y Hatsugai M Kohmoto T Koma YS Wu

PHYSICAL REVIEW B 54(8) 5358-5367 1996年8月

We study statistical characterization of the many-body states in exactly solvable models with internal degrees of freedom. The models under consideration include the isotropic and anisotropic Heisenberg spin chains, the Hubbard chain, and a model ...

Finite-size scaling for correlations of quantum spin chains at criticality

T Koma N Mizukoshi

JOURNAL OF STATISTICAL PHYSICS 83(3-4) 661-726 1996年5月

We study the finite-size scaling behavior of two-point correlation functions of translationally invariant many-body systems al criticality. We propose an efficient method for calculating the two-point correlation functions in the thermodynamic lim...
