Correlations and confinement in non-planar two-dimensional dimer models
A. W. Sandvik, R. Moessner
We study classical hard-core dimer models on the square lattice with links extending beyond nearest-neighbors. Numerically, using a directed-loop Monte Carlo algorithm, we find tha…
No sliding in time
Kirill Shtengel, Chetan Nayak, Waheb Bishara +1
In this letter, we analyse the following apparent paradox: As has been recently proved by Hastings (cond-mat/0305505), under a general set of conditions, if a local Hamiltonian has…
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…
Weak ferromagnetism and spiral spin structures in honeycomb Hubbard planes
M A N Araujo, N M R Peres
Within the Hartree Fock- RPA analysis, we derive the spin wave spectrum for the weak ferromagnetic phase of the Hubbard model on the honeycomb lattice. Assuming a uniform magnetiza…
