Destruction of long-range antiferromagnetic order by hole doping
We study the renormalization of the staggered magnetization of a twodimensional antiferromagnet as a function of hole doping, in the framework of the t-J model. It is shown that the motion of holes generates decay of spin waves into ”particle-hole” pairs, which causes the destruction of the long-range magnetic order at a small hole concentration. This effect is mainly determined by the coherent...
متن کامل1/N expansion and long range antiferromagnetic order.
The staggered magnetization of the Heisenberg antiferromagnet in two dimensions can be systematically approximated by a 1/N expansion. Cancellation between self energy diagrams leads to a Luttingerlike theorem for the ground state. We prove (for a smooth enough self energy) that the long range order of mean field theory (N=∞) survives corrections to all orders of 1/N . Divergences of this serie...
متن کاملQuantum measurement-induced antiferromagnetic order and density modulations in ultracold Fermi gases in optical lattices
Ultracold atomic systems offer a unique tool for understanding behavior of matter in the quantum degenerate regime, promising studies of a vast range of phenomena covering many disciplines from condensed matter to quantum information and particle physics. Coupling these systems to quantized light fields opens further possibilities of observing delicate effects typical of quantum optics in the c...
متن کاملQuantum melting of the long - range antiferromagnetic order and spin - wave condensation in t − J − V model
We consider two-dimensional t − J − V model. The wave function of the ground state is constructed. We demonstrate that the doping by holes results in condensation of the spin-waves, destruction of the long-range antiferromagnetic order and formation of the gap in the spin-wave spectrum. PACS numbers: 71.27.+a, 74.20.Hi, 75.50.Ee It is well known that the long-range antiferromagnetic (AF) order ...
متن کاملLong Range Order and Giant Components of Quantum Random Graphs
Mean field quantum random graphs give a natural generalization of classical Erdős-Rényi percolation model on complete graph GN with p = β/N . Quantum case incorporates an additional parameter λ > 0, and the short-long range order transition should be studied in the (β, λ)-quarter plane. In this work we explicitly compute the corresponding critical curve γc, and derive results on two-point funct...
