A Philosophical Approach to Quantum Field Theory
This text presents an
intuitive and robust mathematical image of fundamental particle physics based on a novel approach to quantum field theory,
which is guided by four carefully motivated metaphysical postulates. In particular, the book explores a dissipative approach
to quantum field theory, which is illustrated for scalar field theory and quantum electrodynamics, and proposes an attractive
explanation of the Planck scale in quantum gravity. Offering a radically new perspective on this topic, the book focuses on
the conceptual foundations of quantum field theory and ontological questions. It also suggests a new stochastic simulation
technique in quantum field theory which is complementary to existing ones. Encouraging rigor in a field containing many mathematical
subtleties and pitfalls this text is a helpful companion for students of physics and philosophers interested in quantum field
theory, and it allows readers to gain an intuitive rather than a formal understanding.
