QM Talks@CBPF: Alexander Bouvrie – 05.02, 16h

Quantum Information Group @ CBPF

Last week we had a great talk by Andrea on the entanglement dynamics of fermionic systems. But think now that a system is composed by two (distinguishable) fermions… is the whole system a fermion in itself? Well, that is exactly the topic of our next QM Talks@CBPF! Alexander Bouvrie (CBPF), aka Alex, will tell us about the statistics of co-fermions and co-bosons. See the details below, and be sure to be around!

Speaker: Alexander Bouvrie (CBPF)

Title: Composite bosons: entangled parts or bosonic whole?

Abstract: Most bosons in nature are composites made of more elementary bosons and fermions. Still, from hadrons to ultracold molecules, these composites behave very similarly to elementary bosons, because the statistics of the underlying constituents is negligible. The deviation from ideal bosonic behavior is quantified by the normalization ratio of the quantum state of N composites. Using tools from quantum information science, the normalization ratio for…
