4:30 pm:

I will first introduce the Luttinger model, solve it using a bosonic description and obtain the spin-charge separation. Then, I will use the Luttinger model as a case study of the field theoretical bosonization. And finally, I will discuss why we can rewrite a fermionic theory in terms of boson degrees of freedom by introducing a constructive approach of bosonization.
