DESCRIPTION:Speakers: Asbjørn Bækgaard Lauritsen (Université Paris-Daup
 hine)\n\nGiven a time-dependent one-particle density\, we show that there 
 exist a unique external potential such that the Schrödinger evolution wit
 h this potential has the prescribed one-particle density. The uniqueness o
 f this potential is the famous Runge--Gross theorem\, which however requir
 es unphysical assumptions. In our approach we can treat also singular inte
 ractions such as Coulomb. The key insight is to use the translation invari
 ance of the system with no external potential.Joint work with Mathieu Lewi
 n and Jakob Oldenburg.\n\nhttps://indico.fysik.su.se/event/9848/
