About this document
Second Quantisation of Operators Explained by Дмитро Скорубський is a document available to read on EtoBox.
Lecture V discusses the second quantised representation of operators in many-particle quantum systems, focusing on one-body and two-body operators. It explains how these operators can be expressed in second quantised form and provides examples, including the total number operator and electron spin operator. The lecture also highlights applications of second quantisation in phonons and interacting electron gases, emphasizing the complexity of interacting field theories compared to free field theories.
