We show that quantum interference can be interpreted in terms of a phase invariant quantity, not unlike the Berry’s phase. Under this interpretation, closed loops in time become fundamental quantum entities, and all quantum states become periodic. Decoherence is then seen to occur naturally as a consequence. This formalism, although counterintuitive, provides another useful way of assigning meaning to quantum probabilities and quasi-probabilities. 
Quantum Interference and Many Worlds: A New Family of Classical Analogies
We present a new way of constructing classical analogies of quantum interference. These analogies share one common factor: they treat closed loops as fundamental entities. Such analogies can be usedExpand


Quantum Mechanical Histories and the Berry Phase
We elaborate on the distinction between geometric and dynamical phase in quantum theory and we show that the former is intrinsically linked to the quantum mechanical probabilistic structure. InExpand
Quantum mechanics: Where the weirdness comes from
Quantum entities can behave like waves, forming interference patterns. But the patterns disappear if you try to watch where each particle goes. An atom interferometer experiment now shows that thisExpand

Modern developments of atomic theory have required alterations in some of the most fundamental physical ideas. This has resulted in its being usually easier to discover the equations that describeExpand
“Quantal” Behavior in Classical Probability
A number of phenomena generally believed characteristic of quantum mechanics and seen as interpretively problematic—the incompatibility and value-indeterminateness of variables, the non-existence ofExpand
Topological transitions in Berry's phase interference effects.
We consider a topological transition which is an abrupt variation from \ensuremath{\pi} to zero of Berry's phase, in the case when it is a phase difference of interfering waves. It manifests itselfExpand
REVIEW ARTICLE: Manifestations of Berry's phase in molecules and condensed matter
Since the appearance of Berry's seminal paper in 1984, geometric phases have been discovered in virtually all fields of physics. Here we address molecules and solids, and we limit our scope to theExpand
The Ithaca interpretation of quantum mechanics
I list several strong requirements for what I would consider a sensible interpretation of quantum mechanics and discuss two simple recent theorems which have important implications for such anExpand
Consistent histories and the interpretation of quantum mechanics
The usual formula for transition probabilities in nonrelativistic quantum mechanics is generalized to yield conditional probabilities for selected sequences of events at several different times,Expand

Space-Time Approach to Non-Relativistic Quantum Mechanics
Non-relativistic quantum mechanics is formulated here in a different way. It is, however, mathematically equivalent to the familiar formulation. In quantum mechanics the probability of an event whichExpand
