Tuning correlation effects with electron-phonon interactions
J. P. Hague, N. d'Ambrumenil
We investigate the effect of tuning the phonon energy on the correlation effects in models of electron-phonon interactions using DMFT. In the regime where itinerant electrons, inst…

Spin-Charge Separation, Anomalous Scaling and the Coherence of Hopping in exactly solved Two Chain Models
Nic Shannon, Yanmin Li, Nicholas d'Ambrumenil
The coherence of transport between two one-dimensional interacting Fermi liquids, coupled by single particle hopping and interchain interaction, is examined in the context of two e…

Bosonization for 2D Interacting Fermion Systems: Non-Fermi Liquid Behavior
Y. Yu, Y. M. Li, N. d'Ambrumenil
Non-Fermi liquid behavior is found for the first time in a two-dimensional (2D) system with non-singular interactions using Haldane's bosonization scheme. The bosonized system is s…
