Lenses in Minkowski space optimize queues by hiding bottleneck units
Eitan Bachmat, Sveinung Erland, Vidar Frette +1
We mathematically construct focal lenses for positive-mass particles in Minkowski space. Particles emanating from a point source, refocus with synchronized proper time regardless o…

Lorentzian geometry based analysis of airplane boarding policies highlights slow passengers first as better
Sveinung Erland, Jevgenijs Kaupužs, Vidar Frette +2
We study airplane boarding in the limit of large number of passengers using geometric optics in a Lorentzian metric. The airplane boarding problem is naturally embedded in a 1+1 di…
