Spin Glass Transition at Nonzero Temperature in a Disordered Dipolar Ising System: The Case of LiHoxY{1-x}F4
Ka-Ming Tam, Michel J. P. Gingras
The physics of the spin glass (SG) state, with magnetic moments (spins) frozen in random orientations, is one of the most intriguing problems in condensed matter physics. While mos…
Retardation effects in the Holstein-Hubbard chain at half-filling
Ka-Ming Tam, S. -W. Tsai, D. K. Campbell +1
The ground state phase diagram of the half-filled one-dimensional Holstein-Hubbard model contains a charge-density-wave (CDW) phase, driven by the electron-phonon (e-ph) coupling,…
Phase Diagram of the Holstein-Hubbard Two-Leg Ladder
Ka-Ming Tam, S. -W. Tsai, D. K. Campbell +1
Using a functional renormalization group method, we obtain the phase diagram of the two-leg ladder system within the Holstein-Hubbard model, which includes both electron-electron a…
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…
