Photoinduced melting and charge order in quarter-filled organic conductors: Itinerant electron systems with competing interactions
Photoinduced charge dynamics in oneand two-dimensional organic conductors are studied theoretically in extended Peierls-Hubbard models. For quasi-one-dimensional (EDO-TTF)2PF6, photoinduced change in the charge order pattern from (0110) to (1010) is accompanied by probe-energy-dependent oscillations of conductivity. This is caused by coexistence of charge order and delocalized electrons. For qu...
متن کاملMetal-insulator and insulator-insulator transitions in the quarter-filled band organic conductors.
The theory of the 2k F and 4k F instabilities in quarter-lled band organic conductors is revisited. The phase angles of the 2k F bond and charge density waves are shown to change as electron correlation is turned on, and this switching of the phase angle is critical for understanding the bond distortion patterns in the real materials. Intersite Coulomb interactions in the real materials must be...
متن کاملCharge order and superconductivity in low-dimensional organic conductors.
We study the coexistent state of the spin density wave (SDW) and the charge density wave (CDW) in a one-dimensional extended Hubbard model. We find that the coexistent state of SDW and CDW is stabilized in various electron-filling cases when band parameters are for organic conductors. The ground state energies have cusp-like minima at n/4m-fillings, where n and m are integers. The maxima of the...
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 ...
