De broglie thesis english translation

He has been a member of the Bureau des Longitudes since Incidentally, this rejection of the hypothesis of a massless photon enabled him to doubt the hypothesis of the expansion of the universe. When I conceived the first basic ideas of wave mechanics in —24, I was guided by the aim to perform a real physical synthesis, valid for all particles, of the coexistence of the wave and of the corpuscular aspects that Einstein had introduced for photons in his theory of light quanta in He has published numerous notes and several papers on this subject, and is the author of more than twenty-five books on the fields of his particular interests.

Sincetogether with young colleagues, Louis de Broglie has resumed the study of an attempt which he made in under the name of the theory of the double solution to give a causal interpretation to wave mechanics in the classical terms of space and time, an attempt which he had then abandoned in the face of the almost universal adherence of physicists to the purely probabilistic interpretation of BornBohrand Heisenberg.

His last work made a single system of laws from the two large systems of thermodynamics and of mechanics: The angular dependence of the diffracted electron intensity was measured, and was determined to have the same diffraction pattern as those predicted by Bragg for x-rays.

Duality of the laws of nature[ edit ] Far from claiming to make "the contradiction disappear" which Max Born thought could be achieved with a statistical approach, de Broglie extended wave—particle duality to all particles and to crystals which revealed the effects of diffraction and extended the principle of duality to the laws of nature.

A Causal Interpretation, Elsevier, Amsterdam, More recent experiments prove the quantum nature of molecules made of atoms and with a mass of 10, amu. Just as the photoelectric effect demonstrated the particle nature of light, the Davisson—Germer experiment showed the wave-nature of matter, and completed the theory of wave—particle duality.

It was later edited and republished in Nobel Lectures. It is also close to that of Leibnizwho posited the necessity of "architectonic principles" to complete the system of mechanical laws.

When Boltzmann and his continuators developed their statistical interpretation of Thermodynamics, one could have considered Thermodynamics to be a complicated branch of Dynamics.

Using Bragg diffraction of atoms and a Ramsey interferometry technique, the de Broglie wavelength of cold sodium atoms was explicitly measured and found to be consistent with the temperature measured by a different method. Furthermore, neutral atoms and even molecules have been shown to be wave-like.

The effect has also been used to explain the spatial version of the quantum Zeno effectin which an otherwise unstable object may be stabilised by rapidly repeated observations. For physicists this idea was important because it meant that not only could any particle exhibit wave characteristics, but that one could use wave equations to describe phenomena in matter if one used the de Broglie wavelength.

At these temperatures, the thermal de Broglie wavelengths come into the micrometre range. While taking an interest in the experimental work carried out by his elder brother, Maurice, and co-workers, he specialized in theoretical physics and, in particular, in the study of problems involving quanta.

However, according to him, there is less duality, in the sense of opposition, than synthesis one is the limit of the other and the effort of synthesis is constant according to him, like in his first formula, in which the first member pertains to mechanics and the second to optics: At the end of the war Louis de Broglie resumed his studies of general physics.

Atom optics Experiments with Fresnel diffraction [8] and an atomic mirror for specular reflection [9] [10] of neutral atoms confirm the application of the de Broglie hypothesis to atoms, i.

He was then conscripted for military service and posted to the wireless section of the army, where he remained for the whole of the war of In addition, he believed that the true mass of particles is not constant, but variable, and that each particle can be represented as a thermodynamic machine equivalent to a cyclic integral of action.

Many French and foreign students have come to work with him and a great deal of doctorate theses have been prepared under his guidance.

This thesis contained a series of important findings which he had obtained in the course of about two years. The purpose of that Institute is to teach and develop mathematical and theoretical physics. Up to his final work, he appeared to be the physicist who most sought that dimension of action which Max Planckat the beginning of the 20th century, had shown to be the only universal unity with his dimension of entropy.

However, until the end of his life de Broglie returned to a direct and real physical interpretation of matter-waves, following the work of David Bohm. That idea seems to match the continuous—discontinuous duality, since its dynamics could be the limit of its thermodynamics when transitions to continuous limits are postulated.

Originally, de Broglie thought that real wave i. This wavefunction gives an appearance of wave behavior to matter, without making real physical waves appear.Using four-vectors, the De Broglie relations form a single equation: = De Broglie's thesis started from the hypothesis, English translation by A.F.
