8. [PLENARY TOPIC] Watching Efimov trimers form across the critical dimension: digital quantum simulation of few-boson unitarity

Gastão Krein (Instituto de Física Teórica, Universidade Estadual Paulista)

Oral Presentation

Modeling nonequilibrium few-body dynamics beyond static ground states presents a fundamental challenge for classical computing due to exponential Hilbert space scaling and real-time sign problems. As a hallmark of universal few-body physics, the Efimov effect dictates that three identical bosons at the unitarity limit ($a \to \infty$) form an infinite geometric cascade of bound trimers. While...

25. Thermal Responses of shifted Newing Function to Topological Defects

Uduakobong Okorie (University of South Africa)

Oral Presentation

Topological defects have attracted considerable interest because of their significant influence on the behaviour and interactions of molecular systems. This study therefore investigates their effects on the thermal properties of selected diatomic molecules within the shifted Newing function framework. The radial Schrodinger equation is solved using the Nikiforov–Uvarov functional analysis...

18. FASnI₂Br as a solid-state materials platform for photovoltaic applications

Duke Oeba (University of South Africa)

28/10/2026, 09:30

Oral Presentation

Solar cells being a clean and renewable energy source help achieve SDG number 7; Affordable and clean energy. The recent solar energy developments are quantum dots, nanomaterials, and perovskite solar cells. Perovskite solar cells have attracted the attention of researchers due to their exemplary high-power conversion efficiencies and numerous advantages over other solar cell generation. It...
