Thermodynamics & Correlation Functions

Turn spectral data into equilibrium states, finite-volume spectra, matrix elements and physical response.

This volume will develop the subjects in the chapter map below. Use the outline to locate the methods and examples you want to study; the individual readings are still being developed.

For a worked entrance available now, the Learn sequence From Bethe states to correlations calculates normalized matrix elements and an exact five-site spin correlation. Its complete finite final-state sum makes selection rules, degeneracy and frequency signs explicit; thermodynamic-limit methods remain future coverage here.
