Hi,

Can anyone please explain the physical meaning of coherence(Quantum Mechanics).

Thanks is advance

Physical meaning of coherence would be that beams of particles (or two parts of the same beam) are coherent if they show interference pattern when they overlap with different offsets.
 
A term "coherent state" has two different meanings: a narrow one meant by A. Neumaier and a broad one meant by zonde.

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
