Anomalous Weak Pointer Shifts as Postselected Interference among Coarse-Grained Histories
Cody Charles Payne, Eliahu Cohen
Anomalous weak values and superoscillations allow a pointer to exhibit an effective shift outside the eigenvalue range of the measured observable. We reformulate this effect in a p…
On trivial Jones--Vassiliev polynomials
Avishy Carmi, Eliahu Cohen
We develop a finite-type framework for studying the Jones polynomial and its ability to distinguish the unknot. The main difficulty is to propagate the vanishing of its finite-type…
Regularization from Superpositions of Time Evolutions
Yakir Aharonov, Eliahu Cohen, Tomer Shushi
Short-time approximations and path integrals can be dominated by high-energy or large-field contributions, especially in the presence of singular interactions, motivating regulator…
Current cross-correlation spectroscopy of Majorana bound states
Michael Ridley, Eliahu Cohen, Christian Flindt +1
The clock speed of topological quantum computers based on Majorana zero mode (MZM)-supporting nanoscale devices is limited by the time taken for electrons to traverse the device. W…
Two times or none?
Michael Ridley, Eliahu Cohen
Attempts to treat time on an equivalent footing with space in quantum mechanics have been apparently dominated by `timeless' approaches, such as the one of Page and Wootters, which…
