Sommerfeld expansion, a method for approximating integrals used in statistical and solid-state physics
In 1910, following a 1909 publication of Sommerfeld, he applied hyperbolic geometry to the special theory of relativity.

In 1925, Born and Werner Heisenberg, who got his doctorate from Sommerfeld in 1923 and completed his Habilitation under Born in 1924, introduced the matrix mechanics formulation of quantum mechanics.
The task brought Sommerfeld close to General Hugh Lenox Scott and American Secretary of War, Lindley Miller Garrison, both of whom he assisted numerous times when American citizens found themselves in trouble in Mexico.
Gerhard Domagk attended school in Sommerfeld until he was 14; the scientist would later win the Nobel Prize in Physiology or Medicine in 1939.
As Maria, had an interest in astronomy from an early age, she took the opportunity of studying with Christopher Arnold, a self-taught astronomer who worked as a farmer in Sommerfeld, near Leipzig.
Through his agent Felix Sommerfeld who became Madero's secret service chief, the German ambassador kept up with political developments in the capital and the fight against uprisings along the Mexican-American border, most notably the revolt of Bernardo Reyes in the fall of 1911 and the uprising of Pascual Orozco in the spring of 1912.
(a) the Bohr–Sommerfeld “solar system” atomic model (with electron spin and the Madelung principle), which provides the magic-number elements that end each row of the table and gives the number of elements in each row,
They maintained close scientific and personal exchanges with the institutes for theoretical physics at the Universities in Munich (Sommerfeld), Göttingen (Max Born), and Copenhagen (Niels Bohr).
