Josephson current flowing through a nontrivial geometry: The role of pairing fluctuations across the BCS-BEC crossover
Verdiana Piselli, Leonardo Pisani, Giancarlo Calvanese Strinati
A realistic description of the Josephson effect at finite temperature with ultra-cold Fermi gases embedded in nontrivial geometrical constraints (typically, a trap plus a barrier)…
Spatial emergence of Off-Diagonal Long-Range Order throughout the BCS-BEC crossover
L. Pisani, P. Pieri, G. Calvanese Strinati
In a superfluid system, Off-Diagonal Long-Range Order (ODLRO) is expected to be exhibited in the appropriate reduced density matrices when the relevant particles (either bosons or…
Gap equation with pairing correlations beyond mean field and its equivalence to a Hugenholtz-Pines condition for fermion pairs
L. Pisani, P. Pieri, G. Calvanese Strinati
The equation for the gap parameter represents the main equation of the pairing theory of superconductivity. Although it is formally defined through a single-particle property, phys…
Entanglement between pairing and screening in the Gorkov-Melik-Barkhudarov correction to the critical temperature throughout the BCS-BEC crossover
L. Pisani, A. Perali, P. Pieri +1
The theoretical description of the critical temperature Tc of a Fermi superfluid dates back to the work by Gor'kov and Melik-Barkhudarov (GMB), who addressed it for a weakly-couple…
Competing electronic states in high temperature phase of NaTiO
Monika Dhariwal, L. Pisani, T. Maitra
First principle density functional theory (DFT) calculations on the high temperature phase of layered triangular lattice system NaTiO have revealed that there exists a collecti…
Density functional study of the electronic and vibrational properties of TiOCl
L. Pisani, R. Valenti, B. Montanari +1
We present the phonon spectrum of TiOCl computed using hybrid density functional theory (DFT). A complete analysis of the spectrum is performed for the space group Pmmn (high symme…
