Bogoliubov inner product

ID: bogoliubov-inner-product

The Bogoliubov inner product is a concept that arises in the context of quantum field theory and many-body physics, particularly in the study of fermionic and bosonic systems. It provides a way to define an inner product for quantum states that involve particle creation and annihilation operators, allowing for the treatment of states that have a varying number of particles.
