Instability of charge ordered states in doped antiferromagnets
Leonid P. Pryadko, Steven Kivelson, Daniel W. Hone
We analyze the induced interactions between localized holes in weakly-doped Heisenberg antiferromagnets due to the modification of the quantum zero point spin wave energy; i.e. the…
Crossovers and Phase Coherence in Cuprate Superconductors
V. J. Emery, S. A. Kivelson
High temperature superconductivity is a property of doped antiferromagnetic insulators. The electronic structure is inhomogeneous on short length and time scales, and, as the tempe…
Doped Antiferromagnets in High Dimension
E. W. Carlson, S. A. Kivelson, Z. Nussinov +1
The ground-state properties of the t-J model on a d-dimensional hypercubic lattice are examined in the limit of large d. It is found that the undoped system is an ordered antiferro…
Electronic Liquid Crystal Phases of a Doped Mott Insulator
S. A. Kivelson, E. Fradkin, V. J. Emery
The character of the ground state of an antiferromagnetic insulator is fundamentally altered upon addition of even a small amount of charge. The added charges agglomerate along dom…
Pairing and Phase Coherence in High Temperature Superconductors
V. J. Emery, S. A. Kivelson, O. Zachar
Mobile holes in an antiferromagnetic insulator form a slowly fluctuating array of quasi one-dimensional metallic stripes, which induce a spin gap or pseudogap in the intervening Mo…
Landau Theory of Stripe Phases in Cuprates and Nickelates
Oron Zachar, S. A. Kivelson, V. J. Emery
We consider a Landau theory of coupled charge and spin-density wave order parameters as a simple model for the ordering that has been observed experimentally in the La_2NiO_4 and L…
