Recurrent Variational Approach to the Two-Leg Hubbard Ladder
Eugene H. Kim, German Sierra, Daniel Duffy
We applied the Recurrent Variational Approach to the two-leg Hubbard ladder. At half-filling, our variational Ansatz was a generalization of the resonating valence bond state. At f…
From the Hubbard to the SO(5) Ladder: A Numerical Study
Daniel Duffy, Stephan Haas, Eugene Kim
The Hubbard Hamiltonian on a two-leg ladder is studied numerically using quantum Monte Carlo and Exact Diagonalization techniques. A rung interaction, , is turned on such that t…
Hole Doping Evolution of the Quasiparticle Band in Models of Strongly Correlated Electrons for the High-T_c Cuprates
Daniel Duffy, Alexander Nazarenko, Stephan Haas +3
Quantum Monte Carlo (QMC) and Maximum Entropy (ME) techniques are used to study the spectral function of the one band Hubbard model in strong coupling including a ne…
Specific Heat of the 2D Hubbard Model
Daniel Duffy, Adriana Moreo
Quantum Monte Carlo results for the specific heat c of the two dimensional Hubbard model are presented. At half-filling it was observed that at very low temperatures.…
