Quite recently Mitas [79] proved a conjecture due to Ceperley [73], stating that the reach of the higher dimensional Fermi gas is ‘maximal’ in the sense that, for a given R 0 and τ
We find in our analysis that the QCP is indeed unstable towards a first order transition as a result of competition. Obviously details of the collapse of a QCP and the resulting
Instead of using the Fermi gas pair susceptibility (as in conventional BCS), we rely on the fact that conformal invariance fixes the analytical form of this response function in
Using a SIN tunneling junction, experimentalists can measure the imaginary part of the full dynamical pair susceptibility χ 00 p in the normal state of the quantum critical metals..
The basic observation of the Hubbard model is that pairing in the critical region is due to an algebraic temperature-dependence of the bare pair susceptibility rather than an
Simons, Condensed Matter Field Theory (Cambridge University Press, Cambridge, UK, 2006)..
Verrassend genoeg zijn er verscheidene wisselwerkende fermionische systemen, bijvoorbeeld normale metalen en 3 He bij lage temperaturen, die op een bevredi- gende manier
In Chapter 6, we propose to use the second order Josephson effect as a di- rect probe of the Cooper channel of quantum critical metals, to shed light on the problem of
