Theory of carrier concentration-dependent electronic behavior in layered cobaltates

H. Li, R. T. Clay, S. Mazumdar

A natural explanation for the carrier concentration-dependent electronic behavior in the layered cobaltates emerges within correlated-electron Hamiltonians with finite on-site and…

Cooperative orbital ordering and Peierls instability in the checkerboard lattice with doubly degenerate orbitals

R. T. Clay, H. Li, S. Sarkar +2

It has been suggested that the metal-insulator transitions in a number of spinel materials with partially-filled t_2g d-orbitals can be explained as orbitally-driven Peierls instab…

Bipolaron Density-Wave Driven By Antiferromagnetic Correlations and Frustration in Organic Superconductors

R. T. Clay, H. Li, S. Mazumdar

We describe the Paired Electron Crystal (PEC) which occurs in the interacting frustrated two-dimensional 1/4-filled band. The PEC is a charge-ordered state with nearest-neighbor sp…

The Paired-Electron Crystal in the Two-Dimensional Frustrated Quarter-Filled Band

H. Li, R. T. Clay, S. Mazumdar

The competition between antiferromagnetic and spin-singlet ground states within quantum spin models and the 1/2-filled band Hubbard model has received intense scrutiny. Here we dem…

Local singlets, frustration, and unconventional superconductivity in the organic charge-transfer solids

R. T. Clay, S. Mazumdar, H. Li

We suggest that superconductivity (SC) in the organic charge transfer solids (CTS) is reached from a Bond-Charge Density Wave (BCDW). We discuss an effective model for the BCDW to…

From valence bond solid to unconventional superconductivity in the organic charge-transfer solids

S. Mazumdar, R. T. Clay, H. Li

We show that superconductivity is absent within the 1/2-filled band triangular lattice repulsive Hubbard model that has been proposed for organic charge-transfer solids. We posit t…
