Magnetism and superconductivity of strongly correlated electrons on the triangular lattice
Cédric Weber, Andreas Laeuchli, Frédéric Mila +1
We investigate the phase diagram of the \tj Model on a triangular lattice using a Variational Monte-Carlo approach. We use an extended set of Gutzwiller projected fermionic trial w…
On simplicity of reduced C*-algebras of groups
Pierre de la Harpe
A countable group is C*-simple if its reduced C*-algebra is a simple algebra. Since Powers recognised in 1975 that non-abelian free groups are C*-simple, large classes of groups wh…
Discovery of a bright quasar without a massive host galaxy
Pierre Magain, Geraldine Letawe, Frederic Courbin +4
Quasars are thought to be powered by the infall of matter onto a supermassive black hole at the centre of massive galaxies. As the optical luminosity of quasars exceeds that of the…
An exactly solvable dissipative transport model
Eric Bertin
We introduce a class of one-dimensional lattice models in which a quantity, that may be thought of as an energy, is either transported from one site to a neighbouring one, or local…
Quantum-to-classical correspondence in open chaotic systems
Henning Schomerus, Philippe Jacquod
We review properties of open chaotic mesoscopic systems with a finite Ehrenfest time tau_E. The Ehrenfest time separates a short-time regime of the quantum dynamics, where wave pac…
Charge fluctuations in open chaotic cavities
M. Buttiker, M. L. Polianski
We present a discussion of the charge response and the charge fluctuations of mesoscopic chaotic cavities in terms of a generalized Wigner-Smith matrix. The Wigner-Smith matrix is…
