Correlated Electronic Properties of Some Graphene Nanoribbons: A DMRG Study
V. M. L. Durga Prasad Goli, Suryoday Prodhan, Sumit Mazumdar +1
The significant electron-electron interactions that characterize the π-electrons of graphene nanoribbons (GNRs) necessitate going beyond one-electron tight-binding description. Exi…
Coulomb Enhanced Superconducting Pair Correlations in the Frustrated Quarter-Filled Band
Niladri Gomes, W. Wasanthi De Silva, Tirthankar Dutta +2
A necessary condition for superconductivity (SC) driven by electron correlations is that electron-electron (e-e) interactions enhance superconducting pair-pair correlations, relati…
The chemical physics of unconventional superconductivity
S. Mazumdar, R. T. Clay
Attempts to explain correlated-electron superconductivity have largely focused on the proximity of the superconducting state to antiferromagnetism. Yet, there exist many correlated…
Organic superconductors: the need to go beyond effective 1/2-filled band models
N. Gomes, R. T. Clay, S. Mazumdar
A frustrated, effective 1/2-filled band Hubbard-Heisenberg model has been proposed to describe the strongly dimerized charge-transfer solid families kappa-(ET)_2X and Z[Pd(dmit)_2]…
Similarities in electronic properties of organic charge-transfer solids and layered cobaltates
Sumit Mazumdar, R. Torsten Clay, Hongtao Li
The apparently counterintuitive carrier concentration-dependent electronic properties of layered cobaltates have attracted wide interest. Here we point out that very similar carrie…
Ground state and finite temperature behavior of 1/4-filled band zigzag ladders
R. T. Clay, J. P. Song, S. Dayal +1
We consider the simplest example of lattice frustration in the 1/4-filled band, a one-dimensional chain with next-nearest neighbor interactions. For this zigzag ladder with electro…
