A surname from German.

plural of Heisenberg picture

(quantum mechanics) A formulation of quantum mechanics in which the operators (observables and others) incorporate a dependency on time, but the state vectors are time-independent, an arbitrary fixed basis rigidly underlying the theory. It stands in contrast to the Schrödinger picture in which the operators are constant, and further serves to define a third, hybrid picture, the interaction picture.

Synonym of Heisenberg uncertainty principle

plural of Heisenberg cut

(quantum mechanics, philosophy of physics) A conceptualised division separating the quantum system being observed from the classical system that comprises the observer's information, knowledge and conscious awareness.

(mathematics) The group of 3×3 upper triangular matrices of the form 1ac\0 1b\0 0 1\ under the operation of matrix multiplication, arising in the description of one-dimensional quantum-mechanical systems.

(physics, quantum mechanics) The principle that there is an absolute limit on the combined accuracy of certain pairs of simultaneous, related measurements, especially that of the position and momentum of a particle. Originally posited as a problem of measurement, it was soon refined as an inherent property of the universe.

(rare) Someone who agrees with the philosophy and theories of Werner Heisenberg.

Of or pertaining to, characteristic of, associated with, or suggestive of Werner Heisenberg, a German theoretical physicist and one of the key pioneers of quantum mechanics.
