"Noise in a chargeless Fermi liquid"
We study the charge of carriers close to the singlet-doublet (parity changing) transition of a superconductor-quantum dot- normal metal junction. Our goal is, in particular, to understand if this charge is influenced by strong interactions. As a first step, we establish a mapping to the Anderson model, and generalize Nozieres' Fermi liquid theory to this latter. We then use our generalized Fermi liquid theory to describe transport in the superconducting device. Though quasiparticles do not have a definite charge in the emerging "chargeless" Fermi liquid theory, a hidden U(1) symmetry - unrelated to the real charge of excitations - and a corresponding pseudo-charge still emerges. In contrast to other correlated Fermi-liquids, the back scattering noise reveals an effective charge equal to the charge of Cooper pairs, e* = 2e, which remains completely unrenormalized by interactions. We also predict a strong suppression of (non-linear) noise at resonance.

"The bag approach to strongly correlated fermions"
The auxiliary field method is the traditional method of choice to perform quantum Monte Carlo calculations in strongly correlated fermion systems. Over the past decade we have developed an alternate method, called "the fermion bag approach" that is complementary to the auxiliary field method. In this talk we discuss the essential ideas behind this approach and show how it allows us to solve some sign problems that seem impossible to solve with the auxiliary field methods. We also show some results from large scale Monte Carlo calculations near a semi-metal-insulator transition that were obtained using the bag approach.
have a nice day!
