Spin squeezing and Bell correlations with ultra-cold atoms in one-dimensional optical lattice
I will discuss a method to obtain scalable spin squeezing in isotropic Heisenberg spin chains that can be obtained using either bosonic or fermionic ultra-cold atoms in optical lattices. In this scheme, spin-flip coupling induces effective interactions among individual spins allowing the production of scalable spin squeezing. I will discuss the influence of boundary conditions on squeezing dynamics. In addition, I will show how to quantify the level of many-body Bell correlations generated in the systems. The schemes can be directly implemented experimentally with state-of-the-art techniques.
