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…
