[Infopoint]

Dear All,

You are most cordially invited to the ICTP Colloquium on "The bizarre 
one-dimensional quantum physics" by Prof. Thierry Giamarchi, Department 
of Quantum Matter Physics, University of Geneva, Switzerland.

The Colloquium will take place TODAY, Wednesday 25 September 2024 at 
14:00 hrs CET, and live-streamed.

Biosketch:

Thierry Giamarchi is a professor in the Department of Quantum Matter 
Physics (DQMP) at the University of Geneva, as well as a member of the 
French Academy of Sciences, and a fellow of the American Physical Society.

His research deals with the effects of interactions in low dimensional 
quantum systems, such as Luttinger liquids, and on the effects of 
disorder in classical and quantum systems with works showing the 
existence of novel disordered phases such as the Bose glass and the 
Bragg glass. His research focusses both on condensed matter realizations 
of these systems, such as organic superconductors and quantum spin 
chains and ladders, but also on cold atomic gases systems that have 
provided a fantastic new playground for looking at quantum physics in 
low dimensions.

Abstract:

To describe the materials that surround us and that we use daily, 
quantum physics has proven to be an essential tool. Through a 
description largely based on a physics without interaction between 
particles, it has allowed to understand many properties of materials. 
However, this description without interaction has its limitations, and 
understanding the effects of interactions represents a huge challenge. 
In the case of systems that are one-dimensional, the interactions 
between particles even lead to a radically new physics compared to what 
we are familiar with in three-dimensional 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 systems, both in terms of the physics itself and 
in terms of the methods for solving such problems.
In this presentation, I will provide an overview of this very particular 
physics and its consequences, such as the existence 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 offered and discuss the 
state of the field and its prospects and challenges for the 21st century.

Light refreshments will be served after the event.
