DESCRIPTION:Speakers: Thierry Giamarchi (University of Geneva\, Switzerlan
 d)\n\nTo describe the materials that surround us and that we use daily\, q
 uantum physics has proven to be an essential tool. Through a description l
 argely based on a physics without interaction between particles\, it has a
 llowed to understand many properties of materials. However\, this descript
 ion without interaction has its limitations\, and understanding the effect
 s of interactions represents a huge challenge. In the case of systems that
  are one-dimensional\, the interactions between particles even lead to a r
 adically new physics compared to what we are familiar with in three-dimens
 ional systems. What may seem like nothing more than a mathematical game or
  an academic curiosity is\, in fact\, extremely important for many systems
  existing in condensed matter or cold atomic gases. The need to understand
  such systems has now become a central point in the physics of quantum sys
 tems\, both in terms of the physics itself and in terms of the methods for
  solving such problems.\nIn this presentation\, I will provide an overview
  of this very particular physics and its consequences\, such as the existe
 nce of fractional charge excitations and topological phase transitions. I 
 will also showcase the experimental scenarios that recent advancements in 
 materials science\, nanotechnology\, and ultracold gas physics have offere
 d\, in particular with the possibility to perform quantum simulations of s
 uch problems and discuss the state of the field and its prospects and chal
 lenges for the 21st century.\n \n\nhttps://indico.hiskp.uni-bonn.de/event
