Ground state and finite temperature signatures of quantum phase transitions in the half-filled Hubbard model on a honeycomb lattice
Thereza Paiva, R. T. Scalettar, W. Zheng +2
We investigate ground state and finite temperature properties of the half-filled Hubbard model on a honeycomb lattice using quantum monte carlo and series expansion techniques. Unl…

Order and disorder in the triangular-lattice t-J-V model at 2/3 electron density
W. Zheng, J. Oitmaa, C. J. Hamer +1
Motivated by the recent discovery of superconductivity in NaCoOHO, we use series expansion methods and cluster mean-field theory to study spontaneous charge orde…
