Phase locking a clock oscillator to a coherent atomic ensemble
R. Kohlhaas, A. Bertoldi, E. Cantin +3
The sensitivity of an atomic interferometer increases when the phase evolution of its quantum superposition state is measured over a longer interrogation interval. In practice, a l…
Weak Unit Disk and Interval Representation of Planar Graphs
Md. Jawaherul Alam, Stephen G. Kobourov, Sergey Pupyrev +1
We study a variant of intersection representations with unit balls, that is, unit disks in the plane and unit intervals on the line. Given a planar graph and a bipartition of the e…
Happy Edges: Threshold-Coloring of Regular Lattices
Md. Jawaherul Alam, Stephen G. Kobourov, Sergey Pupyrev +1
We study a graph coloring problem motivated by a fun Sudoku-style puzzle. Given a bipartition of the edges of a graph into {\em near} and {\em far} sets and an integer threshold $t…
