Effect of a Spin-1/2 Impurity on the Spin-1 Antiferromagnetic Heisenberg Chain
Makoto Kaburagi, Takashi Tonegawa
Low-lying excited states as well as the ground state of the spin-1 antiferro- magnetic Heisenberg chain with a spin-1/2 impurity are investigated by means of a variational method a…

Impurity-Bond Effect on the Spin-1 Antiferromagnetic Heisenberg Chain
Makoto Kaburagi, Isao Harada, Takashi Tonegawa
Low-lying excited states of the spin-1 antiferromagnetic Heisenberg chain with an impurity bond are investigated in terms of domain-wall excitations by means of analytical methods…
