Unusual quasi-one-dimensional electron dispersions in the spin-1/2 quantum magnet TiOCl
M. Hoinkis, M. Sing, J. Schaefer +8
We have studied the electronic structure of the spin-1/2 quantum magnet TiOCl by polarization-dependent momentum-resolved photoelectron spectroscopy. From that, we confirm the quas…
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…
BCS-BEC crossover at finite temperature in the broken-symmetry phase
P. Pieri, L. Pisani, G. C. Strinati
The BCS-BEC crossover is studied in a systematic way in the broken-symmetry phase between zero temperature and the critical temperature. This study bridges two regimes where quantu…
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…
