Spin and charge excitations in the anisotropic Hubbard ladder at quarter filling with charge-ordering instability
Y. Ohta, T. Nakaegawa, S. Ejima
Quantum Monte Carlo and density-matrix renormalization group methods are used to study the coupled spin-pseudospin Hamiltonian in one-dimension (1D) that models the charge-ordering…
