Bipairing and the Stripe Phase in 4-Leg Ladders
Ming-Shyang Chang, Ian Affleck
Density Matrix Renormalization Group (DMRG) calculations on 4-leg t-J and Hubbard ladders have found a phase exhibiting "stripes" at intermediate doping. Such behavior can be viewe…
Impurity Entanglement Entropy and the Kondo Screening Cloud
Erik S. Sørensen, Ming-Shyang Chang, Nicolas Laflorencie +1
The screening of an impurity spin by conduction electrons is associated with the formation of a large Kondo screening cloud, of size xi_K. We study the quantum entanglement between…
Boundary effects in the critical scaling of entanglement entropy in 1D systems
Nicolas Laflorencie, Erik S. Sorensen, Ming-Shyang Chang +1
We present exact diagonalization and density matrix renormalization group results for the entanglement entropy of critical spin-1/2 XXZ chains. We find that open boundary condition…
Renormalization Group Potential for Quasi-One-Dimensional Correlated Systems
Ming-Shyang Chang, Wei Chen, Hsiu-Hau Lin
We studied the correlated quasi-one-dimensional systems by one-loop renormalization group techniques in weak coupling. In contrast to conventional g-ology approach, we formulate th…
Potential Flow of Renormalization Group in Quasi-One-Dimensional Systems
Wei Chen, Ming-Shyang Chang, Hsiu-Hau Lin +2
We address the issue why the phase diagrams for quasi-one-dimensional systems are rather simple, while the renormalization group equations behind the scene are non-linear and messy…
