Exploring the unification of quantum theory and general relativity with a Bose–Einstein condensate

R Howl, R Penrose, I Fuentes - New Journal of Physics, 2019 - iopscience.iop.org
Despite almost a century's worth of study, it is still unclear how general relativity (GR) and
quantum theory (QT) should be unified into a consistent theory. The conventional approach …

Perspectives for a new realization of the pascal by optical methods

K Jousten, J Hendricks, D Barker, K Douglas… - Metrologia, 2017 - iopscience.iop.org
