Generators of the SU(10) group

Now, with the implementation of evolution operators deriving from the generators of the SU(10) group, complete control over the quantum state of the nuclear spins is achievable. This is an opportunity to use the full Hilbert space of strontium 87 atoms in experiments and for quantum technologies, that we explore in our published paper. For example, we use it to measure simultaneously two non-commuting observables of pseudo-spin ensembles!

Probing coherences and itinerant magnetism

We use dynamical decoupling to preserve spin coherence against magnetic fluctuations, which allows us to study itinerant magnetism of lattice-trapped magnetic atoms, driven by magnetic dipole-dipole interactions, in the low-entropy and close-to-unit filling regime. The results are presented in our new paper.

Effective light-induced Hamiltonian for atoms with large nuclear spin

In this paper, we present a systematic derivation of the effective Hamiltonian for the nuclear spin states of ultracold fermionic atoms due to such an off-resonance light. We obtain compact expressions for the scalar, vector, and tensor light shifts taking into account both linear and quadratic contributions to the hyperfine splitting.
