Quantum limit in a quasi-one-dimensional conductor in a high tilted magnetic field
DOI: 10.7868/S0370274X1720005X
Abstract
Recently, we have suggested Fermi-liquid - non-Fermi-liquid angular crossovers which may exist in quasi-one-dimensional (Q1D) conductors in high tilted magnetic fields [see A.G. Lebed, Phys. Rev. Lett. 115, 157001 (2015).] All calculations in the Letter were done by using the quasi-classical Peierls substitution method, whose applicability in high magnetic fields was questionable. Here, we solve a fully quantum mechanical problem and show that the main qualitative conclusions of the above mentioned Letter are correct. In particular, we show that in high magnetic fields, applied along one of the two main crystallographic axis, we have 2D electron spectrum, whereas, for directions of high magnetic fields far from the axes, we have 1D electron spectrum. The later is known to promote non-Fermi-liquid properties. As a result, we expect the existence of Fermi-liquid - non-Fermi-liquid angular crossovers or phase transitions. Electronic parameters of Q1D conductor (Per)2Pt(mnt)2 show that such transitions can appear in feasible high magnetic fields of the order of H \simeq20{-}25 T.
