Comparison between a diagrammatic theory for the BCS-BEC crossover and Quantum Monte Carlo results
P. Pieri, L. Pisani, G. C. Strinati
Predictions for the chemical potential and the excitation gap recently obtained by our diagrammatic theory for the BCS-BEC crossover in the superfluid phase are compared with novel…
Broad versus narrow Fano-Feshbach resonances in the BCS-BEC crossover with trapped Fermi atom
S. Simonucci, P. Pieri, G. C. Strinati
With reference to the broad and narrow Fano-Feshbach resonances of 6Li at about 822 G and 543 G, we show that for the broad resonance a molecular coupled-channel calculation can be…
Conserving and gapless approximations for the composite bosons in terms of the constituent fermions
G. C. Strinati, P. Pieri
A long-standing problem with the many-body approximations for interacting condensed bosons has been the dichotomy between the ``conserving'' and ``gapless'' approximations, which e…
Pairing fluctuation effects on the single-particle spectra for the superconducting state
P. Pieri, L. Pisani, G. C. Strinati
Single-particle spectra are calculated in the superconducting state for a fermionic system with an attractive interaction, as functions of temperature and coupling strength from we…
Fermi liquids and Luttinger liquids
H. J. Schulz, G. Cuniberti, P. Pieri
In these lecture notes, the basic physics of Fermi liquids and Luttinger liquids is presented. Fermi liquids are discussed both from a phenomenological viewpoint, in relation to mi…
