Autor: M. Milićević, G. Montambaux, T. Ozawa, O. Jamadi, B. Real, I. Sagnes, A. Lemaître, L. Le Gratiet, A. Harouri, J. Bloch, A. Amo
Publikováno v: Physical Review X, Vol 9, Iss 3, p 031010 (2019)
The extraordinary electronic properties of Dirac materials, the two-dimensional partners of Weyl semimetals, arise from the linear crossings in their band structure. When the dispersion around the Dirac points is tilted, one can predict the emergence

Persistent Current of Interacting Electrons: a Simple Hartree-Fock Picture
Autor: G. Montambaux
Publikováno v: Journal de Physique I. 6:1-4
The average persistent current of diffusive electrons in the Hartree-Fock approximation is derived in a simple non-diagrammatic picture. The Fourier expansion directly reflects the winding number decomposition of the diffusive motion around the ring.

Quasi-1D conductors in a magnetic field
Autor: G. Montambaux
Publikováno v: Phase Transitions. 30:27-34
This short paper describes some basic features of the magnetic field-induced series of phase transitions in quasi-1D conductors and of their theoretical description. In Bechgaard salts, the nature of the CDW and SD W ordering is changed because of th

Field induced spin density waves in quasi-1D conductors
Autor: G Montambaux
Publikováno v: Physica Scripta. :188-193
We present a review of the unusual physics of the quasi-1D conductors in a magnetic field. They have an open Fermi surface and dramatic magnetic field effects were a priori not expected in these compounds. But they present a very rich phase diagram i

Stabilization of flux states on two-dimensional lattices
Autor: Yasuhiro Hatsugai, Mahito Kohmoto, Yukio Hasegawa, G. Montambaux
Publikováno v: Physical Review B. 41:9174-9182
The total energy of two-dimensional electrons in a uniform magnetic field is systematically calculated for the square lattice, the triangular lattice, and the honeycomb lattice for various ratios of transfer integrals. It has many cusps as a function

Specific-heat study of the anomalous quantum limit of (TMTSF)2ClO4
Autor: James S. Brooks, Jos A. A. J. Perenboom, Long Y. Chiang, G. Montambaux, D. Althof, Michael Graf, N. A. Fortune
Publikováno v: Physical Review Letters. 64:2054-2057
We report calorimetric measurements of the organic conductor (TMTSF${)}_{2}$${\mathrm{ClO}}_{4}$ in the quantum limit. In addition to the field-induced spin-density-wave (FISDW) phases, we have measured the magnetic-field-dependent specific heat asso
