Functional Renormalization Group Analysis of the Half-filled One-dimensional Extended Hubbard Model
Ka-Ming Tam, Shan-Wen Tsai, David K. Campbell
We study the phase diagram of the half-filled one-dimensional extended Hubbard model at weak coupling using a novel functional renormalization group (FRG) approach. The FRG method…
Metal-Insulator-Like Behavior in Semimetallic Bismuth and Graphite
Xu Du, Shan-Wen Tsai, Dmitrii L. Maslov +1
When high quality bismuth or graphite crystals are placed in a magnetic field directed along the c-axis (trigonal axis for bismuth) and the temperature is lowered, the resistance i…
Weak-coupling functional renormalization-group analysis of the Hubbard model on the anisotropic triangular lattice
Shan-Wen Tsai, J. B. Marston
Motivated by experiments on the layered compounds -(BEDT-TTF)X, CsCuCl, and very recently NaCoOHO, we present a weak-coupling functional renormal…
Study of critical behavior of the supersymmetric spin chain that models plateau transitions in the integer quantum Hall effect
Shan-Wen Tsai, J. B. Marston
We use the density-matrix renormalization-group (DMRG) algorithm and finite-size scaling to study a supersymmetric (SUSY) spin chain that models plateau transitions in the integer…
