چکیده
The interplay between doping and antiferromagnetism is a central issue in theories of the oxide superconductors. Undoped La2Cu04 is known to be an antiferromagnetic insulator, and may be modeled by Cu02 planes with a spin2 local moment on each Cu. Sr doping introduces holes into the oxygen p orbitals. Following Anderson's suggestion, ' there has been considerable interest in the "t-J"model of a doped antiferromagnet

Contrasting Pathways to Mott Gap Collapse in Electron and Hole Doped Cuprates
Recent ARPES measurements on the electron-doped cuprate Nd2−xCexCuO4 can be interpreted in a mean field model of uniform doping of an antiferromagnet, with the Mott gap closing near optimal doping. Mode coupling calculations confirm the mean field results, while clarifying the relation between the Mott gap and shortrange magnetic order. The same calculations find that hole doped cuprates should...
متن کاملBosonic mean-field theory of the spiral phases of Heisenberg antiferromagnets on a chain.
We develop a novel bosonic mean field theory to describe the spiral phases of a Heisenberg antiferromagnet on a one-dimensional chain, in terms of three bosons at each site. The ground state is disordered and for large values of the spin S, two different and exponentially small energy gaps are found. The spin-spin correlation function is computed and is shown to decay exponentially at large dis...
متن کاملEffective Theories for Magnetic Systems
In complete analogy to chiral perturbation theory, systematic low-energy effective theories can be used to describe the lightly doped antiferromagnetic precursors of high-temperature superconductors. The spinwaves or magnons are the Goldstone bosons of the spontaneously broken SU(2)s symmetry. The comparison of analytic effective field theory results at the two-loop level and Monte Carlo data o...
متن کاملMean-field theory for alkali-metal-doped polyacetylene.
The Landau theory used by Choi and Mele (CM) to treat their rotor model on a triangular lattice for the orientational ordering of polyacetylene chains in alkali-metal-doped polyacetylene is studied. A reanalysis of the higher-order terms in the Landau expansion indicates that cosine ordering can support a nonzero cubic term in the Landau expansion whereas the sine-ordered phase has no such term...
متن کاملSupersolid phases of a doped valence-bond quantum antiferromagnet: evidence for a coexisting superconducting order parameter.
Motivated by numerical evidence of the valence-bond ground state of the two-dimensional Heisenberg pyrochlore lattice, we argue using a t-J model that it evolves under doping into novel phases characterized by superconductivity coexisting with the underlying valence-bond solid order. A fermionic mean-field theory supplemented by exact diagonalization results provide strong arguments in favor of...
