Winner of the European Union Literature Prize, Peter Terrin's The Guard is a haunting novel of perceived oppression by the an omnipresent, but unknown, authority. In the near future, Harry and Michel live in the basement of a luxury apartment block, guarding the inhabitants. No one goes outside. The world might be at war, it might even have been plunged into nuclear winter. No one knows. But one weekend, all of the residents leave the block, one by one. All but the man on floor 29. Harry and Michel stick to their posts. All they know, all they can hope for, is that if they are vigilant, the "Organization" will reward them with a promotion to an elite cadre of security officers. But what if there were no one left to guard? Playing on our darkest fears, The Guard is a tautly observed novel by a writer of striking and stylish originality.

Sommario/riassunto

This book explores Lieb's Simplified approach to the ground state of systems of interacting bosons. While extensive research has delved into the behavior of interacting bosons, persistent challenges, such as proving Bose-Einstein condensation, remain. Introduced by Lieb in 1963, the Simplified approach has been the object of renewed attention in recent years, revealing surprising and promising results. Notably, this approach provides ground state energy predictions that agree with many-body systems asymptotically at both low and high densities. It further predicts a condensate fraction and correlation function that agree with Bogolyubov theory at low densities, and numerical



predictions match quantum Monte Carlo simulations across all densities. This suggests that Lieb's Simplified approach could serve as a potent tool for reimagining the study of interacting bosons. The book defines Lieb's Simplified approach, discusses its predictions, and presents known analytical and numerical results. It is designed for advanced students and young researchers working in the fields of mathematical physics, quantum many-body physics and Bose-Einstein condensates.
