Geant4 implementation for quantum-dot scintillation in bulk materials

Implement physics processes and material models in Geant4 that simulate quantum dots embedded in bulk scintillators and accurately model nanophotonic scintillation across diverse high-energy particles, scintillator hosts, and nanophotonic environments, moving beyond simplified approaches.

Background

The authors explain that Geant4 excels at particle-matter interaction simulations but currently lacks implementations specific to quantum-dot behavior and nanophotonic scintillation in bulk scintillators used in particle physics contexts.

They point out that existing methods resort to simplifications that do not generalize across particle types or nanostructured environments, creating a gap that must be addressed to accurately predict detector response in quantum-dot–enhanced calorimetry.

The Geant4 toolkit offers advanced capabilities for simulating particle interactions, but its applications have been limited in some important areas. Specifically, there has yet to be an implementation for simulating quantum dots within bulk scintillators in the context of particle physics, nor for modelling nanophotonic scintillation in many existing experiments. Existing approaches often involve simplifications or generalizations that only partially account for arbitrary types of high-energy particles, scintillator materials, and nanophotonic environments.
