Entangled Chemistry: Objectives
Having the electrons participating into the chemical bond all “merged” in the
new bondon—which is a bosonic particle—induces a de-facto
bosonization of
the electrons
in the resulting chemical field. Qualitatively, this is depicted by the
side-by-side diagrams of Fig.

“translating” the MOs of bonding in the actual
bosonic-bondonic picture.
Quantitatively, the bosonization transforms the fermionic field

quantify the (quasi) one-dimensional systems. It roots in the breaking down of
the Fermi liquid theory for 1D-excitations of electrons with linear dispersion
