Quantum Mechanics of Photons
نویسنده
چکیده
We present a short review of the concept of photon wave function and the photon wave equation which represents the Schrödinger equation for the photon. Photon wave function puts the photon on the same footing as particles with mass and presents the first quantization formulation for electromagnetic fields. Because the photon has zero rest mass and it always moves with speed of light, the quantum mechanical formulation is somewhat different from other particles. We present how the concept of photon wave function is developed from the works of Bialynicki-Birula and Sipe and the recent applications of this concept.

Modulation Response and Relative Intensity Noise Spectra in Quantum Cascade Lasers
Static properties, relatively intensity noise and intensity modulation response in quantum cascade lasers (QCLs) studied theoretically in this paper. The present rate equations model consists of three equations for the electrons density in the conduction band and one equation for photons density in cavity length. Two equations were derived to calculate the noise and modulation response. Calcula...
متن کاملQuantum Mechanics and the Mechanism of Sexual Reproduction
There are many claims that quantum mechanics plays a key role in the origin and/or operation of biological organisms. The mechanism of the meiosis, mitosis and gametes life cycle from the view-point of quantum for human has been represented. The quantum gates have been used to simulate these processes for the first time. The reason of several hundred sperms has been explained in the male too

متن کاملA Non-Demolition Photon Counting Method by Four-Level Inverted Y-Type Atom
The semi-classical model of atom-field interaction has been fully studied for some multilevel atoms, e.g. Vee, L, Cascade X , Y, and inverted Y and so on. This issue is developed into the full-quantum electrodynamics formalism, where the probe and coupling electromagnetic fields are quantized. In this article, we investigate the full-quantum model of absorption and dispersion spectrum of trappe...

Innovative Laboratory Design 1 1 3 Advances in several technologies have created an educational opportunity for curricular innovation in physics. Experiments with correlated photons can be used in the upper-level physics curriculum to complement the teaching of an otherwise theoretical topic: quantum mechanics. Undergraduates can now recreate, on a tabletop setup, experiments with correlated ph...
متن کاملPhoton quantum mechanics and beam splitters
We are developing materials for classroom teaching about the quantum behavior of photons in beam splitters as part of a project to create five experiments that use correlated photons to exhibit nonclassical quantum effects vividly and directly. Pedagogical support of student understanding of these experiments requires modification of the usual quantum mechanics course in ways that are illustrat...
