چکیده

We analyze the possibility to prepare a Heisenberg antiferromagnet with cold fermions in optical lattices, starting from a band insulator and adiabatically changing the lattice potential. The numerical simulation of the dynamics in 1D allows us to identify the conditions for success, and to study the influence that the presence of holes in the initial state may have on the protocol. We also extend our results to two-dimensional systems.

Low-energy singlets in the Heisenberg antiferromagnet on the kagomé lattice.

The spin-1/2 Heisenberg antiferromagnet on the kagomé lattice, is mapped by contractor renormalization to a spin-pseudospin Hamiltonian on the triangular superlattice. Variationally, we find a ground state with columnar dimer order. Dimer orientation fluctuations are described by an effective O(2) model at energies above an exponentially suppressed clock mass scale. Our results explain the larg...

Frustrated honeycomb Heisenberg antiferromagnet: A Schwinger-boson approach.

We analyze the frustrated Heisenberg antiferromagnet defined on a honeycomb lattice using a Schwinger-boson mean-field theory. The spin-wave velocity and the susceptibility are presented as functions of the strength of the frustrating interaction for spin S = 12 , and the dynamic structure factor is calculated for various temperatures and frustrations. For large S, we find an increased Néel sta...

Chern-Simons theory of the anisotropic quantum Heisenberg antiferromagnet on a square lattice.

We consider the anisotropic quantum Heisenberg antiferromagnet (with anisotropy λ) on a square lattice using a Chern-Simons (or Wigner-Jordan) approach. We show that the Average Field Approximation (AFA) yields a phase diagram with two phases: a Neèl state for λ > λc and a flux phase for λ < λc separated by a second order transition at λc < 1. We show that this phase diagram does not describe t...

حالت RVB بهینه در شبکه مربعی: حالت پایه و برانگیخته

We consider RVB state as a variational estimate for the ground state of Heisenberg antiferromagnet in square lattice. We present numerical calculation of energy, spin-spin correlation function and spin excitation spectrum. We show, that the quantum flactuations reduce of magnetization respect to Neel order. Our results are in good agreement with other methods such as spin-wave calculation a...

An Upper Bound for the Spin-Wave Spectrum of the Heisenberg Antiferromagnet

We study the spin-wave spectrum of the Heisenberg antiferromagnet on a bipartite lattice. The spin-wave spectrum on a Néel-ordered ground state is bounded as ε(k) ≤ c|k|, where c gives an upper bound for the spin-wave velocity. In the large-S limit, the upper bound c coincides with the result of the spin-wave theory.
