At the nanoscale, quantum effects become significant and classical methods may fail to capture essential properties of systems. PIMC is particularly valuable for studying systems where thermal and quantum fluctuations play a major role. Examples include:
Quantum Dots: PIMC helps in understanding the electronic properties and excitonic effects in quantum dots, which are essential for applications in optoelectronics and quantum computing. Nanowires: The method aids in investigating transport properties and superconductivity in nanowires, impacting the design of nanoscale circuits. Graphene: PIMC can be used to explore the thermal and electronic properties of graphene, which is vital for developing new materials with extraordinary mechanical and electrical properties.
