Chapter 8 The quantum theory of motion
... Classical mechanics It is impossible for a particle to surmount over a barrier with potential energy high than its kinetic energy. Quantum mechanics If the barrier is thin and the barrier energy is not infinite, particles have the probability to penetrate into the potential region forbidden by class ...

Generalising Unitary Time Evolution
... Physics has come a long way by assuming that the laws of nature are invariant under certain space-time transformations. These can include displacements, rotations and changes between frames of reference in uniform relative motion. In quantum theory, transformations of both states |ψi → |ψ 0 i and ob ...

Electron transport in 3D topological insulators
... Topological insulators (TI) are new states of matter, where there exist topologically protected surface and edge states which exhibit spin‐momentum locking. Here, we investigate the theory of electron transport on the topological surface states of topological insulators. The techniq ...

Remember, relativity implies that photons don’t experience time so they cannot change or evolve. • But we can do something to make them change their polarization ...
