One variant of this phenomenon can be used to tune the electronic properties of boron nitride nanotubes from nearly insulating to metallic. Another variant of this phenomenon is induced by interference of standing laser waves to trap atoms of a Bose-Einstein condensate loaded into an optical lattice. Schrdinger's third article from his 1926 series of papers presented his perturbation theory treatment of this effect's modification of the Balmer and Lyman series. Along with van der Waals broadening and resonance broadening, this effect can produce pressure broadening of spectral lines. In addition to the giant version and the AC or Autler-Townes form of this effect, it exhibits variants that are linear and quadratic in the applied field. FTP name this shifting and splitting of spectral lines due to an external electric field, the analogue of the Zeeman effect.

The artists friend Meyer de Haan appears with two semi-nude women surrounded by flowers in his Barbarian Tales. A naked black woman lies on her stomach on a green bed in one painting by this painter. He drew a tree branch to set off the main action taking place on a vermillion background in another work. This painter of Spirits of the Dead Keep Watch and Jacob Wrestling with the Angel also painted a religious figure surrounded by Breton women. He depicted an old woman with a white bird at her feet representing the final stage of life in another painting. For 10 points, name this French painter who painted The Yellow Christ and Where Do We Come From What Are We Where Are We Going while living out his life on Tahiti.

The tensor analog of this quantity can be diagonalized by defining a coordinate system along the principal axes, and its middle eigenvalue corresponds to unstable motion according to Euler's Equations of Motion. The deflection of a cantilevered beam is inversely proportional to Young's modulus and this quantity. It is given by "cross-sectional area times the square of the radius of gyration", and it can be found by the parallel axis theorem. For a sphere it is equal to "two-fifths m r squared", while it has half the value for a disc that it has for a ring. For 10 points, name this quantity symbolized "I", the rotational analog of mass.
