Sensitivity of arrest in mode-coupling glasses to low-q structure
M. J. Greenall, Th. Voigtmann, P. Monthoux +1
We quantify, within mode coupling theory, how changes in the liquid structure affect that of the glass. Apart from the known sensitivity to the structure factor at wavevecto…
Density Fluctuation Mediated Superconductivity
P. Monthoux, G. G. Lonzarich
We conpare predictions of the mean-field theory of supercnductivity for metallic systems on the border of a density instability for cubic and tetragonal lattices. The calculations…
Diagrammatic perturbation theory and the pseudogap
P. Monthoux
We study a model of quasiparticles on a two-dimensional square lattice coupled to Gaussian distributed dynamical fields. The model describes quasiparticles coupled to spin or charg…
Field-induced Antiferromagnetism and the Kondo Insulator-to-Metal Transition
K. S. D. Beach, Patrick A. Lee, P. Monthoux
The Kondo lattice model, augmented by a Zeeman term, serves as a useful model of a Kondo insulator in an applied magnetic field. A variational mean field analysis of this system on…
On Migdal's theorem and the pseudogap
P. Monthoux
We study a model of quasiparticles on a two-dimensional square lattice coupled to Gaussian distributed dynamical molecular fields. The model describes quasiparticles coupled to spi…
Sensitivity of the Superconducting Transition Temperature to Changes in the Spin-Fluctuation Spectral Weight
P. McHale, P. Monthoux
In the simplest model of magnetic pairing, the transition temperature to the superconducting state depends on the dynamical susceptibility . We discuss how is a…
