Â For 10 points, name this 20th century French physicist who developed the concept of special unit cells in reciprocal lattice space, which are his namesake 'zones'.
A function developed by this scientist takes the form of a difference of hyperbolic cotangents with arguments proportional to the ratio of a magnetic moment's Zeeman energy to its thermal energy and is used to determine the magnetization of a paramagnet. He offered a 1951 solution to the problem of Maxwell's demon which introduced uncertainties due to blackbody radiation and introduced a term to link thermodynamics with information, (*) 'negentropy'. This man studied how light undergoes a frequency shift when interacting with acoustic modes, now called his namesake 'scattering'. With Kramers and Wentzel, he developed a method to solve the Schrodinger equation by expanding the wavefunction in the semiclassical limit.
