Ghirardi

Ghirardi may refer to:

• Gian Carlo Ghirardi (1935-2018): An Italian physicist known for his work on the foundations of quantum mechanics, particularly the Ghirardi-Rimini-Weber (GRW) theory. He also contributed to the understanding of spontaneous localization models.

• Ghirardi-Rimini-Weber (GRW) Theory: A model of spontaneous wave function collapse in quantum mechanics, proposed by Gian Carlo Ghirardi, Alberto Rimini, and Tullio Weber. The theory attempts to address the measurement problem in quantum mechanics by modifying the Schrödinger equation to include spontaneous collapses of the wave function.

• Contributions related to spontaneous localization: The concept and mathematical formulation of models that describe the spontaneous collapse of wave functions, leading to the localization of quantum systems in space. Ghirardi's research significantly influenced the development of these models.
