IQC Student seminar featuring Tales Rick Perche

A description of the spin-spin interaction from Quantum Electrodynamics

by Tales Rick Perche

When implementing entangling operations in two quantum systems, it is usual to consider interactions prescribed by Hamiltonians that directly couple the different systems (e.g. the J-coupling). On the other hand, a fundamental description of these systems using quantum field theory is entirely local, which forbids coupling disjoint systems directly. 

In this talk we will discuss how a fully quantum field theoretic treatment of electrons in atoms gives rise to the spin-spin interaction, focusing on the assumptions necessary to reach the effective J-coupling model and the corrections that arise in this more detailed description.
