MSCA TIMES doctoral researcher Petru Milev has published new research results in a peer-reviewed scientific journal, marking an important achievement in his PhD. The work focuses on improving computational methods used to study the optical and electronic properties of materials at the quantum level.
In this study, Petru and collaborators investigate advanced numerical strategies to solve the Bethe–Salpeter equation, a key theoretical framework for describing how electrons interact in materials and how excitations such as excitons emerge. The research compares different computational approaches—based on direct diagonalization and iterative solvers—to efficiently handle large and complex systems.
A central contribution of the work is the demonstration that these methods can significantly improve performance and scalability, enabling simulations of much larger systems than previously feasible. This is particularly relevant for modern high-performance computing architectures, including CPU and GPU platforms, and opens the door to more accurate and predictive simulations in materials science.
These developments are crucial for advancing the theoretical description of materials and can have important implications for the design of next-generation technologies in areas such as optoelectronics and quantum devices.
This publication represents a key milestone in Petru’s doctoral research within the MSCA TIMES project, highlighting the strong progress of its early-stage researchers and their contribution to cutting-edge computational physics.
