Space and time dependent temepreture correlation fucntions in the Hiesenberg XXO chain are evaluated in the magnetic field. The other name of the model is isotropic xy model in the transverse magnetic field. In the thermodynamic limit correlations in the model are represented as Fredhom determinanat. We expect this to to solve the problem of evaluation of asymptotics of temperature correlations.

Thermodynamic Interpretation of the Quantum Error Correcting Criterion
TLDR
This note extends the connection between quantum information theory and thermodynamics to include quantum error correction, and shows that this criterion has a thermodynamical interpretation.
