Measuring a Quantum Measure Exceeding Unity
Sanchari Chakraborti, Rafael D. Sorkin, Urbasi Sinha
The history based formalism known as Quantum Measure Theory (QMT) generalizes the concept of probability-measure so as to incorporate quantum interference. The resulting quantum me…
An intrinsic causality principle in histories-based quantum theory: a proposal
Fay Dowker, Rafael D. Sorkin
Relativistic causality (RC) is the principle that no cause can act outside its future lightcone, but any attempt to formulate this principle more precisely will depend on the found…
An inside view of the tensor product
Rafael D. Sorkin
Given a vector-space which is the tensor product of vector-spaces and , we reconstruct and from the family of simple tensors within . In an ap…
Measurements and analysis of response function of cold atoms in optical molasses
Subhajit Bhar, Maheswar Swar, Urbashi Satpathi +4
We report our experimental measurements and theoretical analysis of the position response function of a cloud of cold atoms residing in the viscous medium of an optical molasses an…
A manifestly covariant framework for causal set dynamics
Fay Dowker, Nazireen Imambaccus, Amelia Owens +2
We propose a manifestly covariant framework for causal set dynamics. The framework is based on a structure, dubbed covtree, which is a partial order on certain sets of finite, unla…
Symmetry-breaking and zero-one laws
Fay Dowker, Rafael D. Sorkin
We offer further evidence that discreteness of the sort inherent in a causal set cannot, in and of itself, serve to break Poincar{é} invariance. In particular we prove that a Poiss…
