Quantum Simulation and Data Science Lab
Major Competencies
The Quantum Simulation and Data Science Lab have experience in developing and using ab initio based methods and scientific software codes for quantum materials modelling and atomistic simulations in response to external stimuli such as light, and electric/magnetic fields. Simulations provide valuable new insights into the chemical and physical process and help us to discover new materials for renewable and sustainable energy. The lab seeks to advance quantum materials modelling and atomistic simulations by exploiting emerging technologies in high-performance computing (HPC), data science (artificial intelligence and machine learning), and quantum computers.
