  2. Lambda function - Wikipedia

    en.wikipedia.org/wiki/Lambda_function

    Dirichlet lambda function, λ(s) = (1 – 2 −s)ζ(s) where ζ is the Riemann zeta function; Liouville function, λ(n) = (–1) Ω(n) Von Mangoldt function, Λ(n) = log p if n is a positive power of the prime p; Modular lambda function, λ(τ), a highly symmetric holomorphic function on the complex upper half-plane

  3. Uncertainty principle - Wikipedia

    en.wikipedia.org/wiki/Uncertainty_principle

    where = is the reduced Planck constant.. The quintessentially quantum mechanical uncertainty principle comes in many forms other than position–momentum. The energy–time relationship is widely used to relate quantum state lifetime to measured energy widths but its formal derivation is fraught with confusing issues about the nature of time.

  4. Lennard-Jones potential - Wikipedia

    en.wikipedia.org/wiki/Lennard-Jones_potential

    The Lennard-Jones potential is a simple model that still manages to describe the essential features of interactions between simple atoms and molecules: Two interacting particles repel each other at very close distance, attract each other at moderate distance, and eventually stop interacting at infinite distance, as shown in the Figure.

  5. Lambda - Wikipedia

    en.wikipedia.org/wiki/Lambda

    The lambda particle is a type of subatomic particle in subatomic particle physics. Lambda is the set of logical axioms in the axiomatic method of logical deduction in first-order logic. There is a poetical allusion to the use of Lambda as a shield blazon by the Spartans. [citation needed] [4] Lambda is the von Mangoldt function in mathematical ...

  6. Zero-point energy - Wikipedia

    en.wikipedia.org/wiki/Zero-point_energy

    In ordinary atomic physics, the zero-point energy is the energy associated with the ground state of the system. The professional physics literature tends to measure frequency, as denoted by ν above, using angular frequency, denoted with ω and defined by ω = 2πν.

  7. Bell's theorem - Wikipedia

    en.wikipedia.org/wiki/Bell's_theorem

    Bell's theorem is a term encompassing a number of closely related results in physics, all of which determine that quantum mechanics is incompatible with local hidden-variable theories, given some basic assumptions about the nature of measurement.

  8. Lambda calculus - Wikipedia

    en.wikipedia.org/wiki/Lambda_calculus

    Recursion is the definition of a function invoking itself. A definition containing itself inside itself, by value, leads to the whole value being of infinite size. Other notations which support recursion natively overcome this by referring to the function definition by name. Lambda calculus cannot express this: all functions are anonymous in ...

  9. Introduction to Solid State Physics - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_Solid...

    Introduction to Solid State Physics, known colloquially as Kittel, is a classic condensed matter physics textbook written by American physicist Charles Kittel in 1953. [1] The book has been highly influential and has seen widespread adoption; Marvin L. Cohen remarked in 2019 that Kittel's content choices in the original edition played a large ...
