The spin-squeezing protocols allow the dynamical generation of massively correlated quantum many-body states, which can be utilized in entanglement-enhanced metrology and technologies. We study a simulator generating twisting dynamics realized two-component Bose-Hubbard model with dipolar interactions. show that interplay contact long-range interactions between atoms superfluid phase activates ...

We study spectral form factor in periodically kicked bosonic chains. consider a family of models where Hamiltonian with the terms diagonal Fock space basis, including random chemical potentials and pairwise interactions, is by another nearest-neighbor hopping pairing terms. show that, for intermediate-range phase approximation can be used to rewrite bistochastic many-body process generated an e...

We investigate in a simple model whether a Jastrow-based approach for a many-body system containing two-body interactions can be exact. By comparison with recent assertions to the contrary, we find that in general the exact wave function is not purely two-body correlated. Nonetheless, we show that the energy estimate obtained from the calculations is as accurate as it can possibly be, suggestin...
