The Nature of Light - What are Photons
... Some seem self-evident, some seem irrelevant, and some seem nonsense to any given person. Yet no two people, even if they are working in the same discipline, agree on which is which. And all of these ideas are, in one way or another, effectively shaping current scientific discussion. ...

Classical Mechanics should be obtained as a limiting case of a Quantum Mechanics formulation.5 Even though in quantum mechanics there is no such a concept as “the velocity of a particle” in the classical sense, still (as we will see in the coming chapters) the new theory provides a reasonable defini ...

Entanglement, which-way measurements, and a quantum erasure Christian Ferrari Bernd Braunecker
... We have presented a simple model that requires knowledge only of two-level systems. Nonetheless, it allows us to explain interesting effects about one-particle quantum interference: Quantum interference appears when a particle can take different indistinguishable paths to arrive at a detector. The k ...

Density-Matrix Description of the EPR “Paradox”
... Pi in eq. (23) summarize our ignorance/knowledge of which pure states are present, while the coefficients ψj in eq. (6) represent intrinsic probabilities (strictly, probability amplitudes) as to what can be observed of the pure state |ψ. Mixed states and their density-matrix description are therefore ...

Because of Heisenberg’s Principle of Uncertainty, we cannot know both the position and the momentum of an electron at a given time. Rather than give exact location of an electron, the q ...

Term Symbols
... Note: Molecular orbitals have symbols corresponding to the quantum number as follows: Symbol: for 0 Symbol: for 1 Symbol: for 2 etc… Further discussions of these topics can be found in Mortimer pages 651 and 663. Term symbols can be used to determine the allowed electronic tran ...

Since every physical quantum system is subject to un-controlled perturbations and we want our Hamiltonian to represent a stable p ...

Quantum Mechanics from Periodic Dynamics: the bosonic case
... we have obtained a consistent interpretation of the wave/particle duality and of the double slit experiment. The uncertainty relation can be easily obtained (we have standing waves) by absorbing the periodic invariance of the phase factor Ēt/~ + 2π either as a time or as an energy variation: ∆E × ∆ ...
