Wrong!!. You are only considering classical phenomena but quantum mechanics has more to say. At absolute zero kelvin, the motion does not ceases and the maximum velocity of a electron corresponds to the kinetic energy equal to the Fermi Energy.
To quote from the link:Even the entropy is not zero for non perfectly-crystalline/ solids at zero kelvin. This is called Residual Entropy. Ice, for example has a residual entropy of 3.4J/K/mol.
Did you not read the first 4 lines?
Assumptions:
vibrations, matter, particles
Definitions:
Zero Kelvin is defined as the state in which all particle motion ceases and entropy is zero/infinite
Actually, I had not even heard of Fermi Energy - thanks for the links!
I especially like the part about "...frustration... may lead to highly degenerate ground states with a nonzero entropy at zero temperature. This implies that if we were to send the crystal lattice to a 'massage parlor' it would end up with zero entropy at zero temperature.
