On Possible Coexistence of Superconductivity and Charge Density Wave in Hole-doped C60
Superconductivity in C60 materials is modeled in terms of an intramolecular, nonretarded attraction. It was shown previously that, at intermediate coupling, the model possesees a state in which s-wave superconductivity coexists with a charge density wave, the latter stabilized by intersite repulsion. The CDW causes Tc to decrease near half filling. We argue that hole-doped C60, for which Tc pea...
متن کاملConventional superconductivity and charge-density-wave ordering in Ba1xNaxTi2Sb2O
We have investigated the low-temperature physical properties of BaTi2Sb2O and Ba1−xNaxTi2Sb2O (x=0.05, 0.1, 0.15, 0.2, 0.25, 0.3) by means of muon spin rotation (�SR) and SQUID magnetometry. Our measurements reveal the absence of magnetic ordering below TDW=58 K in the parent compound. Therefore the phase transition at this temperature observed by magnetometry is most likely due to the formatio...
متن کاملSuperconductivity and Charge Density Wave in ZrTe3−xSex
Charge density wave (CDW), the periodic modulation of the electronic charge density, will open a gap on the Fermi surface that commonly leads to decreased or vanishing conductivity. On the other hand superconductivity, a commonly believed competing order, features a Fermi surface gap that results in infinite conductivity. Here we report that superconductivity emerges upon Se doping in CDW condu...
متن کاملSuperconductivity and charge density wave formation in TlxV6S8
We report on specific heat and resistivity measurements under hydrostatic pressure on the quasi-one dimensional metal TlxV6S8. We studied the interplay between the low temperature superconducting (SC) ground state and a high temperature charge density wave (CDW) instability. We observed a clear dependency of the physical properties of TlxV6S8 on the Tl concentration x. The CDW anomaly is presen...
متن کاملCharge density wave in graphene: magnetic-field-induced Peierls instability
We suggest that a magnetic-field-induced Peierls instability accounts for the recent experiment of Zhang et al. in which unexpected quantum Hall plateaus were observed at high magnetic fields in graphene on a substrate. This Peierls instability leads to an out-of-plane lattice distortion resulting in a charge density wave (CDW) on sublattices A and B of the graphene honeycomb lattice. We also d...
