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

Strongly Correlated Electrons 2015-05-13 v1

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 H1/H0=0.73, H2/H0=0.59,H3/H0=0.49,H4/H0=0.42H_1/H_0 = 0.73, \ H_2/H_0 = 0.59, H_3/H_0 = 0.49, H_4/H_0 = 0.42, where HnH_n is a critical field of a phase transition between the FICDW phases with numbers nn and n+1n+1. The suggested theory is in very good qualitative and quantitative agreements with the existing experimental data in α\alpha-(ET)2_2KHg(SCN)4_4 material.
