2025-03-03 15:00 - 16:00
We investigate cosmic censorship in anti-de Sitter space in holographic models in which the ground state is described by a good singularity.

In Search of Cosmic Topology Using Artificial Intelligence
2025-02-27 15:00 - 16:00
While there has been tremendous success in measuring the geometry of the Universe the question of cosmic topology remains unresolved.

The Standard model and the lattice
2025-01-27 15:00 - 16:00
Chiral symmetry is hard to engineer on the lattice. The origin of this problem can be traced to the Nielsen Ninomiya theorem which in its most naive form forbids the existence of unpaired Weyl fermions on the lattice.

Non-invertible symmetries in Non-Linear Sigma Models
2025-01-13 15:00 - 16:15
By this point it is fairly well known that symmetries can be generalised in many ways including the case where the topological operator that generates the symmetry does not have an inverse.

Design and Implementation of Quantum Algorithms in the Noisy Intermediate Scale Quantum Era
2025-01-10 00:00 - 14:00
Abstract:

Quantum computing is an emerging paradigm that leverages the principles of quantum mechanics to perform calculations potentially more efficiently than classical computing. It is currently at a crucial stage of its development. Despite its rapid advancement and adoption in both academia and industry, there are still significant theoretical and practical challenges that must be overcome before quantum computing can materialize on a large scale. An essential step on this path is the identification of problems that are intractable for classical algorithms, but can be efficiently solved by a quantum computer, thus demonstrating quantum advantage. Although there are various technologies for the implementation of quantum computers, all are affected to a greater or lesser extent by the presence of errors in the qubits. Therefore, it is common to perform a classical post-processing of the results to mitigate these errors. This thesis focuses on the development of quantum algorithms to address problems in fields as varied as Condensed Matter Physics, Game Theory, and Quantum Machine Learning. In addition, advanced error mitigation techniques are presented that allow their implementation on current quantum devices.
