- Abstract
An impurity coupling to both spin and charge degrees of freedom is added to a periodic t- J chain such that its interaction with the bulk can be varied continuously without losing integrability. Ground state properties, impurity contributions to the susceptibilities and low temperature specific heat are studied as well as transport properties. The impurity phase shifts are calculated to establish the existence of an impurity bound state in the holon sector.
