  2. Spin model - Wikipedia

    en.wikipedia.org/wiki/Spin_model

    A spin model is a mathematical model used in physics primarily to explain magnetism. Spin models may either be classical or quantum mechanical in nature. Spin models have been studied in quantum field theory as examples of integrable models. Spin models are also used in quantum information theory and computability theory in theoretical computer ...

  3. Lectures on Theoretical Physics - Wikipedia

    en.wikipedia.org/.../Lectures_on_Theoretical_Physics

    Lectures on Theoretical Physics is a six-volume series of physics textbooks translated from Arnold Sommerfeld's classic German texts Vorlesungen über Theoretische Physik. The series includes the volumes Mechanics , Mechanics of Deformable Bodies , Electrodynamics , Optics , Thermodynamics and Statistical Mechanics , and Partial Differential ...

    en.wikipedia.org/wiki/Lothar_Wolfgang_Nordheim

    Lothar [note 1] Wolfgang Nordheim (November 7, 1899, Munich – October 5, 1985, La Jolla, California) was a German-born Jewish American theoretical physicist.He was a pioneer in the applications of quantum mechanics to solid-state problems, such as thermionic emission, work function of metals, [1] field electron emission, rectification in metal-semiconductor contacts and electrical resistance ...

  5. Pauli–Villars regularization - Wikipedia

    en.wikipedia.org/wiki/Pauli–Villars_regularization

    In theoretical physics, Pauli–Villars regularization (P–V) is a procedure that isolates divergent terms from finite parts in loop calculations in field theory in order to renormalize the theory. Wolfgang Pauli and Felix Villars published the method in 1949, based on earlier work by Richard Feynman, Ernst Stueckelberg and Dominique Rivier. [1]

  6. CPT symmetry - Wikipedia

    en.wikipedia.org/wiki/CPT_symmetry

    The CPT theorem appeared for the first time, implicitly, in the work of Julian Schwinger in 1951 to prove the connection between spin and statistics. [3] In 1954, Gerhart Lüders and Wolfgang Pauli derived more explicit proofs, [4] [5] so this theorem is sometimes known as the Lüders–Pauli theorem.

  7. Theoretical physics - Wikipedia

    en.wikipedia.org/wiki/Theoretical_physics

    Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict natural phenomena. This is in contrast to experimental physics , which uses experimental tools to probe these phenomena.

  8. Spin–statistics theorem - Wikipedia

    en.wikipedia.org/wiki/Spin–statistics_theorem

    The spin–statistics theorem proves that the observed relationship between the intrinsic spin of a particle (angular momentum not due to the orbital motion) and the quantum particle statistics of collections of such particles is a consequence of the mathematics of quantum mechanics.

  9. He argued that the toolbox of physics enables a practitioner like Edward Witten to go beyond standard mathematics, in particular the geometry of 4-manifolds. The tools of a physicist are cited as quantum field theory , special relativity , non-abelian gauge theory , spin , chirality , supersymmetry , and the electromagnetic duality .
