Topic: localisation

Yi-Ting Tu develops a theoretical account of localisation in quasiperiodic potentials. Regularly spaced deep wells separate the timescales for particle transport and information spreading, producing nonergodic extended behaviour. Local mirror symmetries generate hierarchical resonances when interactions are present and support many-body critical states. The talk also examines how these resonances can create rare-region effects despite the absence of the low-disorder regions familiar from random systems.

There are over 30 million people with drug-resistant epilepsy worldwide. When neuroimaging and non-invasive neural recordings fail to localise seizure onset zones (SOZ), intracranial recordings become the best chance for localisation and seizure-freedom in those patients. However, intracranial neural activities remain hard to visually discriminate across recording channels, which limits the success of intracranial visual investigations. In this presentation, I present methods which quantify intracranial neural time series and combine them with explainable machine learning algorithms to localis
