10. An overview of Efimov physics from three to two dimensions

Marcelo Takeshi Yamashita (Institute of Theoretical Physics - Sao Paulo State University)

Oral Presentation

Efimov states were theoretically predicted for the first time in 1970. They appear in a bosonic three-body system with zero total orbital angular momentum when at least two of the two-body subsystems have an s-wave state at zero energy. In this situation, an infinite number of three-body bound states is formed as a consequence of the appearance of an effective potential proportional to...

23. Accelerating the Clean Energy Transition through Data-Driven Computational Materials Design

Dr Kiprono Korir Kiptiemoi (Moi University)

26/10/2026, 14:45

Oral Presentation

The transition to sustainable energy requires the rapid discovery of advanced materials for energy conversion, storage, carbon utilization and clean fuels. The vast materials space and complex structure–property relationships make conventional trial-and-error approaches costly and time-consuming. Computational materials physics, integrating Density Functional Theory (DFT), atomistic modelling,...

43. Shifting Landscape in Materials Modelling — Integrating First-Principles and Machine Learning for Accelerated Materials Discovery (online)

Kingsley Onyebuchi Obodo (University of KwaZulu-Natal, Pietermaritzburg)

26/10/2026, 15:15

Oral Presentation

The rapid evolution of computational materials science is redefining how materials are designed, understood, and optimized. This presentation highlights the transition from traditional first-principles modelling to data-driven materials discovery frameworks. Early work, grounded in Density Functional Theory (DFT), focused on elucidating the electronic, magnetic, and structural properties of...

29. Entering the 2nd decade of Gravitational Wave observations and implications for Multi-Messenger Astronomy

Monos Naidoo (Rhodes University)

26/10/2026, 15:45

Oral Presentation

Detection of Gravitational Waves (GWs) in 2015 provided yet further vindication of Einstein’s General Relativity and its predictions that were made more than a century before. Rates of detection have far surpassed those initially projected. As instrument sensitivity refines and with new detectors coming online in a few years, we expect an explosion of detections to add to the growing...
