Question: What American scientist was the De Broglie–Bohm theory named after?
Context: Louis-Victor-Pierre-Raymond, 7e duc de Broglie ( ; ] or ] ; 15 August 1892 – 19 March 1987) was a French physicist who made groundbreaking contributions to quantum theory.  In his 1924 PhD thesis he postulated the wave nature of electrons and suggested that all matter has wave properties.  This concept is known as the de Broglie hypothesis, an example of wave–particle duality, and forms a central part of the theory of quantum mechanics. Matter waves are a central part of the theory of quantum mechanics, being an example of wave–particle duality.  All matter can exhibit wave-like behavior.  For example, a beam of electrons can be diffracted just like a beam of light or a water wave.  The concept that matter behaves like a wave, proposed by Louis de Broglie in 1924, is also referred to as the de Broglie hypothesis ( ).  Matter waves are referred to as "de Broglie waves". Victor François de Broglie, 2nd duc de Broglie (19 October 171830 March 1804) was a French aristocrat and soldier and a marshal of France.  He served with his father, François-Marie, 1st duc de Broglie, at Parma and Guastalla, and in 1734 obtained a colonelcy. Achille Léonce Victor Charles, 3rd Duke of Broglie (] ; 28 November 1785 – 25 January 1870), fully Victor de Broglie, was a French peer, statesman, and diplomat.  He was the third duke of Broglie and served as president of the Council during the July Monarchy, from August 1830 to November 1830 and from March 1835 to February 1836.  Victor de Broglie was close to the liberal "Doctrinaires" who opposed the ultra-royalists and were absorbed, under Louis-Philippe's rule, by the Orléanists. Maurice-Jean Madeleine de Broglie (Broglie, Eure, 5 September 1766 – 20 June 1821, Paris) was a French aristocrat and bishop.  He was the son of Marshal of France Victor-Francois, Duc de Broglie, created, by Emperor Francis I, Prince of the Holy Roman Empire, a title which was to be hereditary in the family. The de Broglie–Bohm theory, also known as the pilot-wave theory, Bohmian mechanics, the Bohm (or Bohm's) interpretation, and the causal interpretation, is an interpretation of quantum theory.  In addition to a wavefunction on the space of all possible configurations, it also postulates an actual configuration that exists even when unobserved.  The evolution over time of the configuration (that is, the positions of all particles or the configuration of all fields) is defined by the wave function by a guiding equation.  The evolution of the wave function over time is given by Schrödinger's equation.  The theory is named after Louis de Broglie (1892–1987) and David Bohm (1917–1992). Quantum non-equilibrium is a concept within stochastic formulations of the De Broglie–Bohm theory of quantum physics. In physics, the thermal de Broglie wavelength (formula_1) is roughly the average de Broglie wavelength of the gas particles in an ideal gas at the specified temperature.  We can take the average interparticle spacing in the gas to be approximately ("V"/"N") where V is the volume and N is the number of particles.  When the thermal de Broglie wavelength is much smaller than the interparticle distance, the gas can be considered to be a classical or Maxwell–Boltzmann gas.  On the other hand, when the thermal de Broglie wavelength is on the order of or larger than the interparticle distance, quantum effects will dominate and the gas must be treated as a Fermi gas or a Bose gas, depending on the nature of the gas particles.  The critical temperature is the transition point between these two regimes, and at this critical temperature, the thermal wavelength will be approximately equal to the interparticle distance.  That is, the quantum nature of the gas will be evident for David Joseph Bohm FRS (December 20, 1917 – October 27, 1992) was an American scientist who has been described as one of the most significant theoretical physicists of the 20th century and who contributed unorthodox ideas to quantum theory, neuropsychology and the philosophy of mind. Victor-François Marie Léon, 8th duc de Broglie (Paris, 25 March 1949 – Broglie, 12 February 2012) was a French aristocrat and holder of the title of duc de Broglie.
