Over 50 years ago, Quantum Chromodynamics (QCD) emerged as the fundamental description of the strong nuclear interactions. Another major milestone was the formulation in 1974 of the large N limit of QCD where the planar Feynman diagrams make the dominant contributions. This exhibited a connection of QCD with weakly coupled string theory, which has stimulated […]

The Alps (Advanced Lectures in Physics in Switzerland) is a series of junior schools in theoretical physics taking place in the Swiss Mountains. Its principal aim is to lay the foundation for fruitful collaborations between young researchers with a variety of backgrounds.

CERN, CC BY 4.0, via Wikimedia Commons   The year 2024 marks the 60th anniversary of Bell’s theorem, a result that arguably had the single strongest impact on modern foundations of quantum physics, both at the conceptual and methodological level, as well as at the level of its applications in information theory and technology. We […]

  Stage d’initiation à la recherche mathématique aux Diablerets     À qui s’adresse-t-il ?    En priorité aux collégiennes genevoises de 2ème année intéressées par les mathématiques, en raison du grand nombre de demandes l’année passée. Nous accepterons des 3ème années s’il nous reste de la place. Aucune connaissance ou niveau préalable n’est requis, autrement […]

The concept of information permeates both our everyday life as well as our understanding of the universe. With quantum theory and not classical theory at the base, our concept of information needs a fundamental revision. This workshop will take a fresh look at this maturing subject bringing together thinkers of all levels of seniority. Focus […]

This is a recurring workshop, held in Les Diablerets every February for the last 15 years. Workshop will cover current developments in mathematical physics. The emphasis will be on hot topics in statistical mechanics and neighboring areas, to be chosen three motnths before the workshop. There will be 2-3 minicourses, a few invited talks by […]

Quantum physics provides unprecedented possibilities for metrology. In this workshop we aim at exploring new opportunities and challenges arising from the presence of interactions and dissipation in quantum sensors. Many-body interactions lead to non-trivial many-body states and dynamics, which open a whole range of possibilities for metrology. On the one hand, it offers new resources […]

The connections between kinetic theory and fluid mechanics are deeply rooted in the multitude of phenomena that these theories describe. From the classic examples of gas and plasmas dynamics to the recent applications in collective behavior, the multiscale nature of these problems is undoubtedly a fundamental common feature. Kinetic equations are paramount in modeling large […]

The Hilbert scheme of n points on a manifold parametrizes length-n subschemes of M. On the one hand, this is a classifying space of finite codimension ideals in polynomial rings, on the other hand, being one of the most natural moduli spaces, it plays a major role in many classical problems in enumerative geometry, complex […]

Two dimensional conformal field theories (CFTs) are ubiquitous in mathematical physics and as such provide surprising connections between different areas of research. The past decade has seen a surge of powerful techniques using supersymmetry, integrability, and more recently, random geometry/probability to study different aspects of CFTs. For instance, the task of explicitly computing conformal blocks […]

This is the first event in the Quantum Topology Biennial series (QTB), with a particular focus on the interplay between quantum topology and representation theory. The workshop will study interactions between the two fields, including pDG stuctures, non-semisimple TQFTs, modified traces, and the relation between Hilbert schemes of points and triply graded homology. Poster Quantum […]

Registrations are open until December 5. This edition will feature mini courses by Francis Brown (Oxford), Eveliina Peltola (Aalto & Bonn) and Maxim Zabzine (Uppsala).

The quantisation of moduli spaces is of fundamental interest for applications both in mathematics and physics. Such a quantisation has applications in diverse fields such as Chern-Simons theory and knot theory, conformal field theories, integrability (Painlev´e theory,…), gauge theory, the geometric Langlands correspondence and furthermore, it can be obtained from different perspectives and methods. The […]

The mapping class group (in short, MCG) of a surface is a fundamental object of study in topology and in geometry, where it is regarded as the orbifold fundamental group of the moduli space of Riemann surfaces homeomorphic to the surface.

The aim of this workshop is to bring together researchers from both physics- in topological quantum field theory, high energy physics, and condensed matter- and mathematics- higher categories, representation theory, and topology- to report on recent progress and open questions in the study of generalised notions of symmetry. There have been significant recent developments in […]

This is the fifth edition of this informal workshop that brings together researchers working on non-perturbative approaches to Quantum Field Theory (QFT), with special emphasis on scattering amplitudes. Ample time will be allocated for discussions among the specialists on different topics like the conformal bootstrap, 2D integrable S-matrices, lattice field theory, effective field theories and […]
