Quantum Multicriticality
G. T. Oliver, A. J. Schofield
Several quantum critical compounds have been argued to have multiple instabilities towards orders with distinct dynamical exponents. We present an analysis of a quantum multicritic…
Thermoelectric Effects in Anisotropic Systems: Measurement and Applications
T. W. Silk, A. J. Schofield
The Harman method for measuring the thermal conductivity of a sample using the Peltier effect, may also be used to determine the dimensionless figure of merit from just two electri…
Symmetry-breaking Fermi surface deformations from central interactions in two dimensions
J. Quintanilla, M. Haque, A. J. Schofield
We present a mean field theory of the Pomeranchuk instability in two dimensions, starting from a generic central interaction potential described in terms of a few microscopic param…
Effect of disorder on a Pomeranchuk instability
A. F. Ho, A. J. Schofield
We study the effect of disorder on the order parameter equation and transition temperature of a Pomeranchuk-type Fermi-surface instability using replica mean field theory. We consi…
Pomeranchuk instability: symmetry breaking and experimental signatures
J. Quintanilla, C. Hooley, B. J. Powell +2
We discuss the emergence of symmetry-breaking {\it via} the Pomeranchuk instability from interactions that respect the underlying point-group symmetry. We use a variational mean-fi…
Phase diagram and quasiparticle properties of the Hubbard model within cluster two-site DMFT
E. C. Carter, A. J. Schofield
We present a cluster dynamical mean-field treatment of the Hubbard model on a square lattice to study the evolution of magnetism and quasiparticle properties as the electron fillin…
