Breaking the Conventions : Shakespeare, the Fair Young Man and the Dark Lady

The aim of this essay is to show how Shakespeare’s sonnets violated and reversed the conventional ideas in terms of beauty and idealisation. Furthermore, I will examine the way Shakespeare presented his beloved woman as an absolute opposite of the one created by Petrarch, and how he shifted all the divine metaphors from a woman to a fair young man, creating a new object of praise and admiration.

Limits to phase resolution in matter-wave interferometry

We study the quantum dynamics of a two-mode Bose-Einstein condensate in a time-dependent symmetric double-well potential using analytical and numerical methods. The effects of internal degrees of freedom on the visibility of interference fringes during a stage of ballistic expansion are investigated varying particle number, nonlinear interaction sign and strength, as well as tunneling coupling. Expressions for the phase resolution are derived and the possible enhancement due to squeezing is discussed. In particular, the role of the superfluid-Mott insulator crossover and its analog for attractive interactions is recognized.
