An Effective Field Theory Model for One-Dimensional $\mathrm{CH}$ Chains: Effects at Finite Chemical Potential, Temperature and External Zeeman Magnetic Field

Abstract

In this work we use an effective field theory model to investigate doped $(\mathrm{CH}{)}_{\mathrm{x}}$ chains under the influence of an external constant Zeeman magnetic field $B_0$, at zero and finite temperature, in the mean-field approximation and beyond. We consider both homogeneous and inhomogeneous $\Delta (x)$ condensates and briefly discuss the possibility of using these materials as partially polarized 1D organic conductors.
