Paul Adrien Maurice Dirac was born at his parents' home in Bristol, England, on 8 August 1902, [43] and grew up in the Bishopston area of the city. [44] His father, Charles Adrien Ladislas Dirac, was an immigrant from Saint-Maurice, Switzerland, of French descent, [45] who worked in Bristol as a French teacher.
Bra–ket notation, also called Dirac notation, is a notation for linear algebra and linear operators on complex vector spaces together with their dual space both in the finite-dimensional and infinite-dimensional case.
Gamma matrices were introduced by Paul Dirac in 1928. [1] [2] ... The Dirac algebra can be regarded as a complexification of the real algebra Cl 1,3 ...
In mathematical physics, the Dirac algebra is the Clifford algebra, ().This was introduced by the mathematical physicist P. A. M. Dirac in 1928 in developing the Dirac equation for spin- 1 / 2 particles with a matrix representation of the gamma matrices, which represent the generators of the algebra.
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 .
The Dirac delta function as such was introduced by Paul Dirac in his 1927 paper The Physical Interpretation of the Quantum Dynamics. [9] He called it the "delta function" since he used it as a continuous analogue of the discrete Kronecker delta. Mathematicians refer to the same concept as a distribution rather than a function.
The Dirac–von Neumann axioms can be formulated in terms of a C*-algebra as follows.. The bounded observables of the quantum mechanical system are defined to be the self-adjoint elements of the C*-algebra.
The Dirac bracket is a generalization of the Poisson bracket developed by Paul Dirac [1] to treat classical systems with second class constraints in Hamiltonian mechanics, and to thus allow them to undergo canonical quantization.
