Effect of van Hove Singularities on a Spin Liquid
L. B. Ioffe, A. J. Millis
We determine the properties and leading instabilities of a spin liquid with a Fermi surface passing near a van Hove singularity. Our study is motivated by recent photoemission expe…
Glass Formation in a Periodic Long-Range Josephson Array
P. Chandra, M. V. Feigelman, L. B. Ioffe
We present an analytic study of a dynamical instability in a periodic long-range Josephson array frustrated by a weak transverse field. This glass transition is characterized by a…
Theory of the Spin Gap in High Temperature Superconductors
B. L. Altshuler, L. B. Ioffe, A. J. Millis
We analyze pairing in two dimensional spin liquids. We argue that interplane pairing enhanced by magnetic correlations is the most plausible explanation of the spin gap phenomenon…
The density wave phase transition in a two dimensional Fermi liquid is first order
B. L. Altshuler, L. B. Ioffe, A. J. Millis
We study spin density wave transitions in two dimensional Fermi liquids in which the ordering wavevector is such that the tangents to the Fermi line at the points con…
Pedestrian Approach to the Two-Channel Kondo Model
P. Coleman, L. Ioffe, A. M. Tsvelik
We reformulate the two-channel Kondo model to explicitly remove the unscattered charge degrees of freedom. This procedure permits us to move the non-Fermi liquid fixed point to inf…
Magnetic Properties of High Temperature Superconductors: a Spin Liquid Approach. Talk given at Stanford Spectroscopy Meeting, 1995.
L. B. Ioffe, A. J. Millis
We argue that strongly correlated two dimensional electrons form a spin liquid in some regimes of density and temperature and give the theory of the magnetic properties of this spi…
