Broglie

(brô`yə, brôglē`), French noble family of Piedmontese origin, who settled in France in the 17th cent. Victor Maurice, comte de Broglie, 1647–1727, was marshal of France and fought in the wars of King Louis XIV. His son François Marie, duc de Broglie, 1671–1745, marshal of France, fought at Malplaquet (1709), in the War of the Polish Succession, and in the War of the Austrian Succession. King Louis XV conferred on him the ducal title inherited by his son Victor François, duc de Broglie, 1718–1804, marshal of France, who distinguished himself in the War of the Austrian Succession and the Seven Years War. Holy Roman Emperor Francis I made him prince of the Holy Roman Empire (1757), a title that remained in the family. In the French Revolution he emigrated and commanded (1792) the army of the princes against the revolutionary forces. Charles François, comte de Broglie, 1719–81, brother of Victor François, was ambassador to Poland (1752) and later headed the "secret cabinet" of Louis XV, the king's secret organization of political advisers and spies. Achille Charles Léon Victor, duc de Broglie, 1785–1870, grandson of Victor François, was a statesman and diplomat under Emperor Napoleon I and a leader of the moderate liberals after the Restoration. He occupied several cabinet posts, including that of premier (1835–36), under King Louis Philippe, and was (1847–48) ambassador to London. After the February Revolution (1848) he was elected (1849) to the assembly. He opposed Emperor Napoleon III. He married a daughter of Mme de Staël. His son, Jacques Victor Albert, duc de Broglie, 1821–1901, was a historian and politician. He was a member of the national assembly (1871), ambassador to London (1871–72), premier (1873–74; 1877), and a liberal monarchist leader in the senate. He wrote Histoire de l'église et de l'empire romain au IVe siècle (6 vol., 1856–66), an apologia for the Church as preserver of civilization in the late Roman period, and also edited the memoirs of his father (tr. 1887). He was the grandfather of the scientists Maurice, duc de BroglieBroglie, Maurice, duc de,

In the PV theory the interaction of the electron with the vacuum state leads to the Compton-(de Broglie) relations [3]
Experimental confirmation of the hypothesis of de Broglie wave properties of electrons was carried out outstanding Britain experimental physicist George Thomson (1892-1975)--the son of the previously mentioned master of the world of physics Joseph John Thomson, who, irrespective of American experimental physicists Clinton Davisson (1881-1958) and Lester Germer (1896-1971) in 1927 discovered the diffraction of low-energy electrons (<<cathode rays>>) on a single crystal of nickel Ni [3, 4].
As mentioned previously, the solutions of the STCED wave equations are similar to Louis de Broglie's "double solution".
Treating this vanishing force as a Lorentz invariant constant then leads to the important Compton-(de Broglie) relations for the electron [6]
Louis de Broglie first put the wavesinto quantum mechanics with his theory of matter waves: that every piece of matter has a wave associated with it or a wave aspect to its nature.
The force difference [DELTA][F'.sub.3] = 0 in (7) gives the de Broglie relation
In agreement with de Broglie and Bohm most proponents of hidden variables would now say that the hidden variable [lambda] of the system actually present in box 1 should not depends of the overall phase existing between [[PSI].sub.1] and [[PSI].sub.2].
Thus Beckmann's de Broglie relation is in relativistic agreement with the PV result.
That is, the classical concept of two particles exerting a force on each other corresponds to the quantum mechanical concept that the de Broglie wave of one particle influences the de Broglie wave of another particle.
The wave-particle duality was first enunciated by Louis de Broglie in 1923.
