Measuring the time a tunnelling atom spends in the barrier
Ramón Ramos, David Spierings, Isabelle Racicot +1
Tunnelling is one of the most paradigmatic and evocative phenomena of quantum physics, underlying processes such as photosynthesis and nuclear fusion, as well as devices ranging fr…

Interpreting weak value amplification with a toy realist model
Josiah Sinclair, David Spierings, Aharon Brodutch +1
Constructing an ontology for quantum theory is challenging, in part due to unavoidable measurement back-action. The Aharonov-Albert-Vaidman weak measurement formalism provides a me…

Atom-optics knife-edge: Measuring narrow momentum distributions
Ramón Ramos, David Spierings, Shreyas Potnis +1
By employing the equivalent of a knife-edge measurement for matter-waves, we are able to characterize ultra-low momentum widths. We measure a momentum width corresponding to an eff…
