Topological Bose-Mott insulators in a one-dimensional optical superlattice.
We study topological properties of the Bose-Hubbard model with repulsive interactions in a one-dimensional optical superlattice. We find that the Mott insulator states of the single-component (two-component) Bose-Hubbard model under fractional fillings are topological insulators characterized by a nonzero charge (or spin) Chern number with nontrivial edge states. For ultracold atomic experiment...
متن کاملPair Correlations in Doped Hubbard Ladders
Hubbard ladders are an important stepping stone to the physics of the two-dimensional Hubbard model. While many of their properties are accessible to numerical and analytical techniques, the question of whether weakly hole-doped Hubbard ladders are dominated by superconducting or charge-density-wave correlations has so far eluded a definitive answer. In particular, previous numerical simulation...
متن کاملMott domains of bosons confined on optical lattices.
In the absence of a confining potential, the boson-Hubbard model exhibits a superfluid to Mott insulator quantum phase transition at commensurate fillings and strong coupling. We use quantum Monte Carlo simulations to study the ground state of the one-dimensional bosonic Hubbard model in a trap. Some, but not all, aspects of the Mott insulating phase persist. Mott behavior occurs for a continuo...
متن کامل2 00 2 Competing phases in the extended U - V - J Hubbard model near the van Hove fillings
The phase diagram of the two-dimensional extended U-V-J Hubbard model is considered within a mean-field approximation and a renormalization group (RG) approach near the van Hove band fillings. While charge-and spin-flux phases are not stable at the mean-field level, they are identified as possible ground states in some parameter range within the RG treatment. We argue that in the parameter rang...
متن کاملروش انتگرال مسیر برای مدل هابارد تک نواره
We review various ways to express the partition function of the single-band Hubard model as a path integral. The emphasis is made on the derivation of the action in the integrand of the path integral and the results obtained from this approach are discussed only briefly. Since the single-band Hubbard model is a pure fermionic model on the lattice and its Hamiltonian is a polynomial in creat...
