Charge-order transition in the extended Hubbard model on a two-leg ladder
Matthias Vojta, R. E. Hetzel, R. M. Noack
We investigate the charge-order transition at zero temperature in a two-leg Hubbard ladder with additional nearest-neighbor Coulomb repulsion V using the Density Matrix Renormaliza…

Vortex-Loop Unbinding and Flux-Line Lattice Melting in Superconductors
Anh Kiet Nguyen, A. Sudbo, R. E. Hetzel
We study the interplay between a novel vortex-loop unbinding in finite magnetic field at T=T_V and flux-line lattice (FLL) melting at T=T_M in type-II superconductors. The FLL melt…
