Quantum Pasts and the Utility of History
James B. Hartle
From data in the present we can predict the future and retrodict the past. These predictions and retrodictions are for histories -- most simply time sequences of events. Quantum me…
Comment on ``Consistent Sets Yield Contrary Inferences in Quantum Theory''
Robert B. Griffiths, James B. Hartle
In a recent paper Kent has pointed out that in consistent histories quantum theory it is possible, given initial and final states, to construct two different consistent families of…
Generalized Quantum Theory in Evaporating Black Hole Spacetimes
James B. Hartle
Quantum mechanics for matter fields moving in an evaporating black hole spacetime is formulated in fully four-dimensional form according to the principles of generalized quantum th…
Comparing Formulations of Generalized Quantum Mechanics for Reparametrization-Invariant Systems
James B. Hartle, Donald Marolf
A class of decoherence schemes is described for implementing the principles of generalized quantum theory in reparametrization-invariant `hyperbolic' models such as minisuperspace…
Quantum Cosmology: Problems for the 21st Century
James B. Hartle
Two fundamental laws are needed for prediction in the universe: (1) a basic dynamical law and (2) a law for the cosmological initial condition. Quantum cosmology is the area of bas…
Sources of Predictability
James B. Hartle
Sources of predictability in the basic laws of physics are described in the most general theoretical context -- the quantum theory of the universe as a whole. (To appear in the Pro…
