... should be equal to – cos2a. Thus if a=0 there is perfect anti-correlation, no two parallel spins to be detected. If a=1800, both measurements are perfectly correlated. If a=900 the measurements are not correlated. If, however, the axis form some other angle the measurements exhibits some non-trivial ...

5 Bose-Einstein condensate (BEC)
... We show, using an exactly solvable model, that nonlinear dynamics is induced in a double-well BoseEinstein condensate (BEC) by collisions with a thermal reservoir. This dynamics can facilitate the creation of phase or number squeezing and, at longer times, the creation of macroscopic nonclassical su ...

Quantum Condensed Matter Field Theory
... From analytical dynamics and fluid mechanics, to electrodynamics and quantum mechanics, lectures can often leave an impression that to each problem in physics a specific and formal exact solution is at hand. Such misconceptions are often reinforced by the allure of sophisticated analytical machinery ...
