An effective field theory model for one-dimensional CH chains: effects at finite chemical potential, temperature and external Zeeman magnetic field

In this work we use an effective field theory model to investigate doped (CH)x chains under the influence of an external constant Zeeman magnetic field B0, at zero and finite temperature, in the mean-field approximation and beyond. We consider both homogeneous and inhomogeneous Δ(x) condensates and calculate the Pauli magnetization and the magnetic susceptibility of these chains in various situations for the temperature and chemical potentials. We also briefly discuss the possibility of using these materials as partially polarized 1D organic conductors
