Absence of long-range superconducting correlations in the frustrated 1/2-filled band Hubbard model
S. Dayal, R. T. Clay, S. Mazumdar
We present many-body calculations of superconducting pair-pair correlations in the ground state of the half-filled band Hubbard model on large anisotropic triangular lattices. Our…
Beyond the quantum spin liquid concept in frustrated two dimensional organic superconductors
R. T. Clay, S. Dayal, H. Li +1
The occurrence of antiferromagnetism in kappa-(ET)_2X can be understood within an effective 1/2-filled band with dimers of ET molecules containing one hole each. We argue that whil…
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…
The Paired Electron Crystal: order from frustration in the quarter-filled band
S. Dayal, R. T. Clay, H. Li +1
We present a study of the effects of simultaneous charge- and spin-frustration on the two-dimensional strongly correlated quarter-filled band on an anisotropic triangular lattice.…
