This colloquium will be held at 3 pm on Friday 21st August.

The usual wisdom is that only particles with integer spin obey Bose statistics and hence only those particles can form Bose condensate. However, in some cases the spin-statistics relation can be violated and particles with half-integer spin obey Bose statistics. Examples of such violation are under discussion in solids and in cosmology (dark matter).
