Disproportionation and Critical Interaction Strength in NaCoO: Concentration Dependence
K. -W. Lee, W. E. Pickett
We present results of studies of charge disproportionation (CD) and spin differentiation in NaCoO using the correlated band theory approach (local-density approximation+Hub…
NaCoO in the x -> 0 Regime: Coupling of Structure and Correlation effects
K. -W. Lee, W. E. Pickett
The study of the strength of correlations in NaCoO is extended to the x=0 end of the phase diagram where Mott insulating behavior has been widely anticipated. Inclusion of…
Disproportionation Transition at Critical Interaction Strength: NaCoO
K. -W. Lee, J. Kunes, P. Novak +1
Charge disproportionation (CD) and spin differentiation in NaCoO are studied using the correlated band theory approach. The simultaneous CD and gap opening seen previou…
Charge Disproportionation and Spin-Ordering Tendencies in Na(x)CoO2 at x=1/3
J. Kunes, K. -W. Lee, W. E. Pickett
The strength and effect of Coulomb correlations in the (superconducting when hydrated) x~1/3 regime of Na(x)CoO(2) have been evaluated using the correlated band theory LDA+U method…
