Importance of phase fluctuations in superconductors with small superfluid density

VJ Emery, SA Kivelson - Nature, 1995 - nature.com
THE superconducting state of a metal is characterized by a complex order parameter with
an amplitude and a phase. In the BCS-Eliashberg mean-field theory1, which is a very good …

Ising Model for the Transition and Phase Separation in - Mixtures

M Blume, VJ Emery, RB Griffiths - Physical review A, 1971 - APS
A spin-1 Ising model, which simulates the thermodynamic behavior of He 3-He 4 mixtures
along the λ line and near the critical mixing point, is introduced and solved in the mean-field …

Electronic liquid-crystal phases of a doped Mott insulator

SA Kivelson, E Fradkin, VJ Emery - Nature, 1998 - nature.com
The character of the ground state of an antiferromagnetic insulator is fundamentally altered
following addition of even a small amount of charge 1 . The added charge is concentrated …

Phase separation in the t-J model

VJ Emery, SA Kivelson, HQ Lin - Physical review letters, 1990 - APS
It is shown that, for the tJ model, dilute holes in an antiferromagnet are unstable against
phase separation into a hole-rich and a no-hole phase. When the spin-exchange interaction J …

Superconductivity in bad metals

VJ Emery, SA Kivelson - Physical Review Letters, 1995 - APS
We introduce a model of the superconducting transition in a bad metal, and show that quantum
and classical phase fluctuations prevent long-range order unless the resistivity ρ (T) falls …

Backward scattering in the one-dimensional electron gas

A Luther, VJ Emery - Physical Review Letters, 1974 - APS
An exact solution to the one-dimensional electron gas with a particular attractive-interaction
strength for scattering across the Fermi" surface" is given. It is shown that conductivity …

Spin-gap proximity effect mechanism of high-temperature superconductivity

VJ Emery, SA Kivelson, O Zachar - Physical Review B, 1997 - APS
When holes are doped into an antiferromagnetic insulator they form a slowly fluctuating
array of “topological defects”(metallic stripes) in which the motion of the holes exhibits a self-…

Frustrated electronic phase separation and high-temperature superconductors

VJ Emery, SA Kivelson - Physica C: Superconductivity, 1993 - Elsevier
There is a strong tendency for dilute holes in an antiferromagnet to phase separate. (This is
a generic feature of doping into a commensurate correlated insulating state.) We review the …

Stripe phases in high-temperature superconductors

VJ Emery, SA Kivelson… - Proceedings of the …, 1999 - National Acad Sciences
Stripe phases are predicted and observed to occur in a class of strongly correlated materials
describable as doped antiferromagnets, of which the copper-oxide superconductors are the …
