The fidelity approach to the Hubbard model
L. Campos Venuti, M. Cozzini, P. Buonsante +3
We use the fidelity approach to quantum critical points to study the zero temperature phase diagram of the one-dimensional Hubbard model. Using a variety of analytical and numerica…
Maximally entangled fermions
Dirk-M. Schlingemann, Marco Cozzini, Michael Keyl +1
Fermions play an essential role in many areas of quantum physics and it is desirable to understand the nature of entanglement within systems that consists of fermions. Whereas the…
Tkachenko modes in a superfluid Fermi gas at unitarity
Gentaro Watanabe, Marco Cozzini, Sandro Stringari
We calculate the frequencies of the Tkachenko oscillations of a vortex lattice in a harmonically trapped superfluid Fermi gas. We use the elasto-hydrodynamic theory by properly acc…
