TITLE: Has there been further work on Bender-Brody-Müller approach to RH?
QUESTION [12 upvotes]: Earlier this year (April 4, 2017), a seemingly tantalizing approach of the Riemann Hypothesis based on ideas dating back to Hilbert and Pólya by Bender, Brody and Müller was made publicly available. I remember having read a criticism thereof later, but remain ignorant of what happened since then. A quick googling only brings out blog articles that don't seem to give real news on its status. So, has the heuristics presented in the considered paper been comforted by some further work or not ?

REPLY [3 votes]: A new paper in Physical Review Letters on related approaches:https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.127.241602
Also, a summary appears in Physics :https://physics.aps.org/articles/v14/s157
