In all three cases, statistical mechanics attempts to evaluate the probability from first principles, using the Hamiltonian of the closed system. In an equilibrium state, the probability does not depend on t ...

It is obvious that after our single collision the particle’s density matrix ˆ , whatever it was before the collision, becomes perfect diagonal in P储. Gradually, after many collisions, the state ˆ becomes a mixture of plane waves, no off ...

Topological Coherence and Decoherence
... How do REAL Solids (%99.9999) behave at low Energy? In almost all real solids, a combination of frustrating interactions, residual long-range interactions, and boundaries leads to a very complex hierarchy of states. These often have great difficulty communicating with each other, so that the long-t ...
