Resumen:
The notion of entanglement in systems of distinguishable constituents is built upon the tensor product structure of the joint Hilbert space. In fermionic systems this structure is no longer present, which prevents the straightforward extension to such systems of entanglement measures already defined in the distinguishable case. Mainly two different approaches have been taken in generalizing the concept of entanglement to fermion systems: Entanglement between modes, and entanglementbetween particles. In this work we introduce a new measure of entanglement betweenmodes and show that its minimum over unitary transformations in single particlespace is a measure of entanglement between particles, which reduces to anothermeasure previously introduced for two-fermion systems.
