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…
Pearling Instabilities of Membrane Tubes with Anchored Polymers
Ilan Tsafrir, Dror Sagi, Tamar Arzi +4
We have studied the pearling instability induced on hollow tubular lipid vesicles by hydrophilic polymers with hydrophobic side groups along the backbone. The results show that the…
Coiling of Cylindrical Membrane Stacks with Anchored Polymers
Vidar Frette, Ilan Tsafrir, Marie-Alice Guedeau-Boudeville +3
We study experimentally a coiling instability of cylindrical multilamellar stacks of phospholipid membranes, induced by polymers with hydrophobic anchors grafted along their hydrop…
Tracer Dispersion in a Self-Organized Critical System
Kim Christensen, Álvaro Corral, Vidar Frette +2
We have studied experimentally transport properties in a slowly driven granular system which recently was shown to display self-organized criticality [Frette {\em et al., Nature} {…
