This is the fourth video in my quantum theory playlist. i give a detailed explanation of bra ket notation (aka dirac notation) and highlight why it works due.
Bra Ket Notation Youtube Hello!this is the sixth chapter in my series "maths of quantum mechanics." in this episode, we'll intuitively understand what the bra is in quantum mechanics. The bra ket notation is a simple way to refer to a vector with complex elements, any number of dimensions, that represents one state in a state space. the probability of any state equals the magnitude of its vector squared. math explained in easy language, plus puzzles, games, quizzes, videos and worksheets. Where we used the notation in (6.6). our bras are labelled by vectors: the object inside the (| is a vector. but bras are : not. vectors. if kets are viewed as column vectors, then bras are viewed as row vectors. in this way a bra to the left of a ket makes sense: matrix multiplication of a row vector times. Lecture 9: dirac's bra and ket notation. description: in this lecture, the professor talked from inner products to bra kets, projection operators, adjoint of a linear operator, hermitian and unitary operators, uncertainty of the hermitian operator, etc. instructor: barton zwiebach. transcript. download video.

In quantum mechanics, bra–ket notation is used ubiquitously to denote quantum states. the notation uses angle brackets, and , and a vertical bar , to construct "bras" and "kets". a ket is of the form . mathematically it denotes a vector, , in an abstract (complex) vector space , and physically it represents a state of some quantum system. The first thing that bra ket notation is really used a lot for is to denote very simply the eigenvectors of a (usually hermitian) operator associated with an eigenvalue. suppose we have an eigenvalue equation a(v) = λv, this can be denoted as a|λ = λ|λ , and probably some extra label k if there is some degeneracy a|λ, k = λ|λ, k .
