De Broglie wave

15 The Principles of Quantum Mechanics. I. De Broglie Waves and the Schrodinger Equation 

Prince Louis Victor de Brogiie, 1892-1977, won the Nobei Prize in physics in 1929 for this work. 

According to Einstein s theory of relativity, a particle of energy E has a mass m such that 

We omit de Broglie s argument, which is more complicated than simply saying that Eq. (15.1-3) is analogous to Eq. (15.1-2). 

De Broglie had shown that it was not necessary to assume quantization in the hydrogen atom as a hypothesis if one assumes the matter-wave relation of Eq. (15.1-3) for the motion of the electron. This proposal of matter waves was revolutionary. When

In wave mechanics the wave function 4>a(x) of a system in a state is specified by the label a. For example, in the case of a free particle a could be the momentum p, and ipa(x) would be the de Broglie wave function,... 

Atomic-beam diffraction was first demonstrated in 1930, as a verification of the concept of the de Broglie wave (Estermann and Stem, 1930). In the 1970s, it was developed into an extremely informative method for determining topography and atomic structure of solid surfaces (Steele, 1974 Goodman and Wachman, 1976).

Matter is classically particulate in nature, but it also manifests wave character. The wave property of matter is related to its particle nature by de Broglie s relation A = hip, where A is known as the de Broglie wave length. 

A nonrelativistic particle is moving five times as fast as a proton. The ratio of their de Broglie wave lengths is 10. Calculate the mass of the particle. 

This is an example of the de Broglie wave-particle duality. The resulting wave equation is... 

It is assumed that the eigenfunction (x) operated on by these infinitesimal field generators is such that the same relation (803) holds between eigenvalues of the field. In order for this to be true, the eigenfunction must be the de Broglie wave function, specifically, the phase of the classical electromagnetic field. On the 0(3) level, this is a line integral, as we have seen.

However, the results obtained for de Broglie waves of the particles in the deuteron nucleus are in favor of presence of muons rather than pions, in the deuteron. The reason for this conclusion is that there is resonance between a nucleon s and a muon s de Broglie waves [5], which would not be the case if pions were taken as participating objects in the deuteron.2... 

The possibility for resonance between photons with de Broglie waves of the particles is elaborated on in Refs. 4 and 14. 

It is however possible to discuss several special cases analytically. The zero temperature correlation length can still be observed as long as this is smaller than the thermal de Broglie wave length At which can be rewritten for K not too close to Ku as t < f/y Kt(, KtK" 1 with tu Lpl, where we defined tk via = jj-, analogously to the definition of At, and used (30). We call this domain the quantum disordered region. 

Fig. 5. The low temperature crossover diagram of a one-dimensional CDW. t and K are proportional to the temperature and the strength of quantum fluctuations, respectively. The amount of disorder corresponds to a reduced temperature tu 0.1. In the classical and quantum disordered region, respectively, essentially the t = 0 behavior is seen. The straight dashed line separating them corresponds to At 1, i.e., K 1, where At is the de Broglie wave length. In the quantum critical region, the correlation length is given by At- Pinning (localization) occurs only for t = 0, K
