Quantum fluctuations and vortex-antivortex unbinding in the 2D BCS-BEC crossover
L. Salasnich, G. Bighin
Very recently quasi two-dimensional (2D) systems made of attractive fermionic alkali-metal atoms with a widely tunable interaction due to Fano-Feshbach resonances have been realize…
Superfluid density in cuprates: hints on gauge compositeness of the holes
P. A. Marchetti, G. Bighin
We show that several features (the three-dimensional XY universality for moderate underdoping, the almost-BCS behaviour for moderate overdoping and the critical exponent) of the su…
Gaussian fluctuations in the two-dimensional BCS-BEC crossover: finite temperature properties
G Bighin, L Salasnich
The role of fluctuations is enhanced in lower dimensionality systems: in a two dimensions off-diagonal long-range order is destroyed by the fluctuations at any finite temperature,…
Universality in cuprates: a gauge approach
P. A. Marchetti, G. Bighin
In high- cuprates many quantities exhibit a non-Fermi liquid universality hinting at a very peculiar structure of the underlying pairing mechanism for superconductivity: in th…
