Can matter and antimatter be present in equal amounts on large scale structure of the universe?

If we believe in baryon number conservation as a universal law. The matter and antimatter must have created in equal amounts during the first few microseconds of big-bang. Therefore the antimatter...

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...

Chemical potential is zero for bosonic system like in superfluid system?

Why we cant apply in other ensembles?

Riyaz Ahmed Bhat

No I do not mean that....my mean is whether we need to modify the formula for non-zero chemical potential or the same formula holds even for mu=0. please comment
