Green's functions are just a powerful mathematical technique to simplifying calculations in quantum many-body theory. Central to these applications is the theory of barrier and potential scattering,which, through application of the Green's function method yields transcendental equations for the scattered wave function thereby requiring approximation methods to be employed. At this scale, the physics of the devices becomes very complex, and shows signatures typical of quantum mechanics, such as confinement and tunneling.

Whatever doesn't parse neatly in a given linguistic system can become a source of anxiety to the culture that speaks this language, calling forth special ritual acts whose function, Douglas argues, is actually to acknowledge the limits of language itself. Physics itself is riven by the competing frameworks of quantum theory and general relativity, whose differing descriptions of our world eerily mirror the wave-particle tension. In a sense they have no real physical content. The Helmholtz, Schr¨odinger and Klein-Gordon equations all have a similar form (for constant wavelength) and have applications in optics, quantum mechanics and relativistic quantum mechanics, respectively. Quantum Bayesianists interpret this as meaning that the quantum state or the wave function, i.e. In this context, theory and modeling are expected to play an increasing role in the exploration of innovative concepts for The most versatile approach for that purpose is the non equilibrium Green's functions method. Green's function - Wikipedia, the free encyclopedia Green's functions are also a useful tool in solving wave equations, diffusion equations, and in quantum mechanics,. We obtain a general expression for the noise kernel of a quantum field defined at two distinct points in an arbitrary curved spacetime as products of covariant derivatives of the quantum field's Green function. The basic idea, I believe, is to frame quantum theory as if it were a guide for an observer to bet on the outcome of experiments (of course this is more of an analogy as betting does not actually comes into it).
