Universal Field-Induced Charge-Density-Wave Phase Diagram: Theory versus Experiment

Abstract

We suggest a theory of the Field-Induced Charge-Density-Wave (FICDW) phases, generated by high magnetic fields in quasi-low-dimensional conductors. We demonstrate that, in layered quasi-one-dimensional conductors, the corresponding critical magnetic fields ratios are universal and do not depend on any fitting parameter. In particular, we find that $H_1/H_0=0.73,H_2/H_0=0.59,H_3/H_0=0.49,H_4/H_0=0.42$, where $H_n$ is a critical field of a phase transition between the FICDW phases with numbers $n$ and $n+1$. The suggested theory is in very good qualitative and quantitative agreements with the existing experimental data in $\alpha$-(ET)${}_2$KHg(SCN)${}_4$ material.
