Bogoliubov Transformations Beyond Shale-Stinespring: Generic for bosons
Sascha Lill
We construct an extension of Fock space and prove that it allows for implementing bosonic Bogoliubov transformations in a certain extended sense. While an implementation in the reg…

Implementing Bogoliubov Transformations Beyond the Shale-Stinespring Condition
Sascha Lill
We provide two extensions of a dense subspace of Fock space, such that Bogoliubov transformations become implementable on them, even though they violate the Shale-Stinespring condi…
