Há 4 dias · In particle physics, the Dirac equation is a relativistic wave equation derived by British physicist Paul Dirac in 1928. In its free form , or including electromagnetic interactions, it describes all spin-1/2 massive particles , called "Dirac particles", such as electrons and quarks for which parity is a symmetry .
Há 1 dia · In mathematical analysis, the Dirac delta function (or δ distribution ), also known as the unit impulse, [1] is a generalized function on the real numbers, whose value is zero everywhere except at zero, and whose integral over the entire real line is equal to one. [2] [3] [4] Since there is no function having this property ...
Há 3 dias · People. Paul Adrien Maurice Dirac OM FRS [6] ( / dɪˈræk /; 8 August 1902 – 20 October 1984) was an English mathematical and theoretical physicist who is considered to be one of the founders of quantum mechanics and quantum electrodynamics. [7] [8] He is credited with laying the foundations of quantum field theory.

Há 4 dias · Now, topological insulators, hosting Dirac-type surface states, provide a unique platform to experimentally examine such quantum Hall physics in curved space. Hence, extending previous work we consider solutions of the Dirac equation for the pseudosphere for both the case of an overall perpendicular magnetic field and a homogeneous ...
Há 3 dias · The Dirac Equation, proposed by Paul Dirac in 1929, describes the behavior of fermions, particles such as electrons, in a relativistic quantum mechanical framework. This equation bridged the gap between quantum mechanics and Einstein’s theory of relativity. Dirac predicted the existence of antimatter.
Há 3 dias · In this paper, the time-independent Klein-Gordon equation in R3 is treated with a decomposition of the operator Δ−γ2I by the Clifford algebra Cl (V3,3). Some properties of integral operators associated the kind of equations and some Riemann-Hilbert boundary value problems for perturbed Dirac operators are investigated.
