Doped two-leg ladder with ring exchange
G. Roux, S. R. White, S. Capponi +2
The effect of a ring exchange on doped two-leg ladders is investigated combining exact diagonalization (ED) and density matrix renormalization group (DMRG) computations. We focus o…
Numerical Contractor Renormalization Method for Quantum Spin Models
Sylvain Capponi, Andreas Laeuchli, Matthieu Mambrini
We demonstrate the utility of the numerical Contractor Renormalization (CORE) method for quantum spin systems by studying one and two dimensional model cases. Our approach consists…
Current Carrying Ground State in a Bi-layer Model
Sylvain Capponi, Congjun Wu, Shou-Cheng Zhang
Strongly interacting systems have been conjectured to spontaneously develop current carrying ground states under certain conditions. We conclusively demonstrate the existence of a…
Spin and charge dynamics of the ferromagnetic and antiferromagnetic two-dimensional half-filled Kondo lattice model
S. Capponi, F. F. Assaad
We present a detailed numerical study of spin and charge dynamics of the two-dimensional Kondo lattice model with hopping t and exchange J. At T=0 and J > 0, the competition betwee…
