Are there any papers demonstrating phase-measurement sensitivity beyond the standard quantum limit?

All the research papers I found so far, are just showing measurement of the squeezing parameter or quantum Fisher Information (QFI). Of course authors mention that, due to large QFI or strong...

Are there any numerical packages to study Fermi-Hubbard model?

I need to determine numerically the ground state energy of the Fermi-Hubbard model when total filling is n=1, but the number of fermions with spin up: 'n_up', and spin down: 'n_down' can take any...

What is the finite size scaling of the Bose-Hubbard energy gap?

I would like to know if the energy gap between ground state and the first excited state in a Bose-Hubbard model have been determined? In particular I would like to know how does it scale with the...

Where can I find s-wave scattering lengths of optical transition states for Sr-88 and Yb-174?

Strontium-88 and Ytterbium-174 are bosonic isotopes with clock transition between singlet and triplet states: 1S0 - 3P0. Do you know of a paper where s-wave scattering lengths for collisions...
