Navigating Quantum and AI Career Trajectories: A Beginner’s Mini-Course on Computational Methods and their Applications
The dynamic field of quantum physics and artificial intelligence is expanding across both academic and industrial landscapes. This mini-course offers an introduction to computational techniques currently utilized in the quantum sector, highlighting non-academic career paths for individuals interested in quantum physics and machine learning. The program features two lecture series: one on generative modeling - covering topics (such as restricted Boltzmann machines, recurrent neural networks, and transformers) - and the other on quantum machine learning algorithms. Participants will also benefit from practical coding tutorials, networking opportunities, and related events about the landscape of Quantum and AI.

Theoretical and Practical Perspectives in Geophysical Fluid Dynamics
The Earth’s climate is dictated by atmospheric and oceanic dynamics, spanning over a wide range of temporal and spatial scales that undergo multi-scale interactions resulting in energy transfers across a multitude of scales. The energy transfers across these multi-scale regimes are key to the understanding of the energy cycle, but their quantification remains poorly constrained. Physical processes such as turbulent mixing and instabilities are difficult to observe or resolve in the numerical models and are often parametrized. Consequently, the question of energy-consistent closure in ocean and climate models, which heavily rely on parametrizations, remains open and challenging to address. To address these questions, a combination of analytical theories, numerical models, and observational measurements is necessary to advance our understanding of oceanic and atmospheric dynamics.The meeting spans two weeks addressing multi-scale and multi-physics topics in geophysical fluid dynamics inc...

Theoretical and empirical approaches to understand polygenic adaptation
Understanding phenotypic variation in terms of the underlying genetic variation is one of the central problems in biological evolution. During the last decade, valuable insights into the genetic architecture of phenotypic traits have been obtained and it is found that many phenotypic traits ranging from crop yield and human height to complex diseases are polygenic, that is, they are influenced by a large number of genetic variants. Despite this evidence, evolutionary biology continues to be dominated by two extreme views of adaptive dynamics where adaptation occurs either via large changes at a few genetic loci or infinitesimal changes at a very large number of them. The aim of this program is to integrate these two seemingly disparate ideas into a single framework and extend their ambit to include other modes of adaptation, and address how one can describe other scenarios quantitatively and relate them to empirical data.The program will feature pedagogical lectures, research seminars ...

Workshop on Data Assimilation in Weather and Climate models
Data assimilation is a mathematical approach employed by leading operational weather forecast centers worldwide. Its primary purpose is to estimate the most accurate atmospheric state and its associated uncertainties by integrating observations and short-range forecasts. Data assimilation methodologies extend beyond weather prediction; they play a crucial role in monitoring and comprehending climate and its variability through reanalysis of historical data. This versatile tool is instrumental in investigating processes within the domains of Land, Atmosphere, and Oceans.The field of Data Assimilation is unfortunately constrained by a scarcity of well-trained scientists and researchers familiar with its theoretical foundations and practical applications. To address this gap, we are organizing a two-week workshop with a specific focus. This workshop aims to provide comprehensive training by introducing fundamental data assimilation theory and facilitating hands-on sessions, particularly f...

Foundations of Quantum Computational Advantage
The workshop marks the halfway point of the similarly named (FoQaCiA, pronounced "focaccia") collaboration between researchers in Canada and Europe, funded as part of a flagship partnership between NSERC and Horizon Europe.
https://www.foqacia.org/
The goal of FoQaCiA is to develop new foundational approaches to shed light on the relative computational power of quantum devices and classical computers, helping to find the "line in the sand" separating tasks admitting a quantum speedup from those that are classically simulable.
The workshop will focus on the four central interrelated themes of the project:
1. Quantum contextuality, non-classicality, and quantum advantage
2. The complexity of classical simulation of quantum computation
3. The arithmetic of quantum circuits
4. The efficiency of fault-tolerant quantum computation
Our view is that the future success of quantum computing critically depends on advances at the most fundamental level, and that large-scale investments in quantum implementations will only pay off if they can draw on additional foundational insights and ideas:: :: ::

Understanding the Universe Through Neutrinos
The Standard Model (SM) of particle physics has been very successful in numerous tests over the past several decades. However, the SM can not be the ultimate theory to explain all the fundamental interactions in the Universe because of critical gaps. The neutrino sector is one of the few places where the physics beyond standard has been confirmed through the observation of neutrino oscillations, a phenomenon which cannot occur with the massless neutrinos predicted by the standard model. Neutrinos are elementary particles with spin ½, zero electric charge, and tiny but non-zero masses. They come in three distinct flavors and can oscillate among themselves as they propagate. Since they only feel the weak force, their cross section for interacting with matter is extremely small. In collider experiments, they can only be identified as “missing energy.” Consequently, large specialized experiments had to be built for studying neutrinos. These neutrino experiments have evolved from single-pur...

Strong Gravity 2023/24
This course will introduce some advanced topics in general relativity related to describing gravity in the strong field and dynamical regime. Topics covered include properties of spinning black holes, black hole thermodynamics and energy extraction, how to define horizons in a dynamical setting, formulations of the Einstein equations as constraint and evolution equations, and gravitational waves and how they are sourced. -
Quantum Gravity 2023/24
The course centers on an in-depth study of the symmetry structure of General Relativity and how this is intimately related to its dynamics and to the challenges posed to its quantization. To achieve this understanding, we will introduce a host of concepts and techniques, broadly (and loosely) known under the name of “Covariant Phase Space Method”. This provides a different perspective on GR’s physics, a perspective in which phase space, rather than spacetime, is front and center. We will apply these ideas and techniques to discuss the so-called Problem of Time, Wald's approach to black hole entropy as a Noether charge, and the relationship between Dirac's Hypersurface Deformation Algebra and GR's symmetries and dynamics. We will also discuss the problem of detecting single gravitons as well as crucial analogies and differences between a quantum electromagnetic and gravitational field. Lecture notes specific for the course will be provided. -
String Theory 2023/24
