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…

Renormalization Group Approach to Strong-Coupled Superconductors
S. -W. Tsai, A. H. Castro Neto, R. Shankar +1
We develop an asymptotically exact renormalization group (RG) approach that treats electron-electron and electron-phonon interactions on equal footing. The approach allows an unbia…

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…
