Correlation functions of an interacting spinless fermion model at finite temperature
Kohei Motegi, Kazumitsu Sakai
We formulate correlation functions for a one-dimensional interacting spinless fermion model at finite temperature. By combination of a lattice path integral formulation for thermod…

Form factors and correlation functions of an interacting spinless fermion model
Kohei Motegi, Kazumitsu Sakai
Introducing the fermionic R-operator and solutions of the inverse scattering problem for local fermion operators, we derive a multiple integral representation for zero-temperature…
