An Introduction to Lieb's Simplified approach to the Bose gas
Ian Jauslin
This is a book about Lieb's Simplified approach to the Bose gas, which is a family of effective single-particle equations to study the ground state of many-body systems of interact…

Evidence of a liquid phase in interacting Bosons at intermediate densities
Ian Jauslin
In this paper, we present evidence for a liquid-like phase in systems of many interacting Bosons at intermediate densities. The interacting Bose gas has been studied extensively in…

The Simplified approach to the Bose gas without translation invariance
Ian Jauslin
The Simplified approach to the Bose gas was introduced by Lieb in 1963 to study the ground state of systems of interacting Bosons. In a series of recent papers, it has been shown t…
