Decoherence and Classicality in Quantum Systems

This chapter examines the role of decoherent histories in quantum mechanics, illustrating how quantum states can lead to branching multiverse paths. It highlights the relationship between quantum systems and classical behavior, discussing the conditions under which quantum phenomena can be perceived classically. Through the exploration of open quantum systems and particle interactions, the chapter uncovers the complexities of decoherence and its implications in both experimental setups and theoretical models.
