Theory of Coexisting Charge and Spin - Density Waves in s TMTTF d 2 Br , s TMTSF d 2 PF 6 , and a - s BEDT - TTF d 2 M Hg
نویسنده
چکیده
Recent experiments indicate that the spin-density waves (SDWs) in sTMTTFd2Br, sTMTSFd2PF6, and a-sBEDT-TTFd2MHgsSCNd4 are highly unconventional and coexist with charge-density waves (CDWs). We present a microscopic theory of this unusual CDW-SDW coexistence. A complete understanding requires the explicit inclusion of strong Coulomb interactions, lattice discreteness, the anisotropic two-dimensional nature of the lattice, and the correct band filling within the starting Hamiltonian.

Bond-order and charge-density waves in the isotropic interacting two-dimensional quarter-filled band and the insulating state proximate to organic superconductivity
We report three surprising results regarding the nature of the spatial broken symmetries in the twodimensional ~2D!, quarter-filled band with strong electron-electron interactions that provides a microscopic model of the 2:1 cationic organic charge-transfer solids ~CTS’s!. First, in direct contradiction to the predictions of one-electron theory, we find a coexisting ‘‘bond-order and charge-dens...
متن کاملLow-Dimensional Organic Conductors under High Maghetic Fields
Novel electromc properties of Iow-dimensional organic conductors.under high magnetic fields are briefly reviewed and some topical problems are discussed. Magnetic field effects to electron spins and electron orbital motions are discussed in the quasi one-dimensional conductors (RIR2DCNQI)2Cu and (TMTSF)2X and in the quasi two-dimensional conductor (BEDT-TTF)2XHg(SCN)4. Electronic properties in ...

Quasi-One and quasi-two dimensional organic conductors consisting of TTF derivatives such as BEDT-TTF (bis-(ethylene-dithio)-tetra-thia-fulvalene) and TMTCF (C = S; TMTTF: tetra-methyl-tetra-thia-fulvalene, C = Se; TMTSF: tetra-methyl-tetraselena-fulvalene) have been well investigated in condensed matter physics because of interest in the emerging electric and magnetic properties, such as the s...
متن کاملPhase diagram of quarter-filled band organic salts [EDT-TTF-CONMe2]2X, X=AsF6 and Br.
An investigation of the P-T phase diagram of the quarter-filled organic conductors, [EDT-TTF-CONMe2]2X is reported on the basis of transport and NMR studies of two members, X=AsF6 and Br of the family. The strongly insulating character of these materials in the low-pressure regime has been attributed to a remarkably stable charge-ordered state confirmed by 13C NMR and the only existence of 1/4 ...
متن کاملAspects of unconventional density waves
Recently many people discuss unconventional density waves (i.e. unconventional charge density waves (UCDW) and unconventional spin density waves (USDW)). Unlike in conventional density waves, the quasiparticle spectrum in these systems is gapless. Also these systems remain metallic. Indeed it appears that there are many candidates for UDW. The low temperature phase of α-(BEDT-TTF)2KHg(SCN)4, th...
