Quantum Mechanical in a sentence

Dirac's approach is also called second quantization or quantum field theory ; citation citation citation earlier quantum mechanical treatments only treat material particles as quantum mechanical, not the electromagnetic field.

Assume the following time average exists: : For quantum mechanical systems, an important assumption made in the quantum logic approach to quantum mechanics is the identification of yes-no questions to the lattice of closed subspaces of a Hilbert space.

In quantum field theory, quantum mechanical interactions between particles are described by interaction terms between the corresponding underlying quantum fields.

Quantum numbers main Because of the quantum mechanical nature of the electrons around a nucleus, atomic orbitals can be uniquely defined by a set of integers known as quantum numbers.

Formal quantum mechanical definition Atomic orbitals may be defined more precisely in formal quantum mechanical language.

Quantum mechanical description The complete quantum mechanical description was first performed by Bethe and Heitler.

At these scales, quantum mechanical effects are important — which coined the term " quantum wires ".

For example, it is an open question whether all quantum mechanical events are Turing-computable, although it is known that rigorous models such as quantum Turing machines are equivalent to deterministic Turing machines.

Helium II is a superfluid, a quantum mechanical state (see: macroscopic quantum phenomena ) of matter with strange properties.

Logic gates can be made from quantum mechanical effects (though quantum computing usually diverges from boolean design).

One of the first quantum effects to be explicitly noticed (but not understood at the time) was a Maxwell observation involving hydrogen, half a century before full quantum mechanical theory arrived.

String theories are quantum theories of gravity in the sense that they reduce to classical general relativity plus field theory at low energies, but are fully quantum mechanical, contain a graviton, and are thought to be mathematically consistent.

The relative state interpretation of quantum mechanics is an attempt to understand the experience of observers using only quantum mechanical notions.

The enhancement of chemical reactions via quantum mechanical processes has been a long-sought research goal for some time now.

All possibilities co-exist forever and the only reality is the quantum mechanical wave function.

An external electromagnetic field at a frequency associated with a transition can affect the quantum mechanical state of the atom.

A paper on "A Quantum Mechanical Calculation of the Elastic Constants of Monovalent Metals" was published in the Proceedings of the Royal Society in 1936.

A quantum mechanical state being a summary of the observer's information about an individual physical system changes both by dynamical laws, and whenever the observer acquires new information about the system through the process of measurement.

Aspect's results show experimentally that Bell's inequality is in fact violated—meaning that the relevant quantum mechanical predictions are correct.

A theory by Ahmed Farag Ali and Saurya Das adds quantum mechanical corrections (using Bohm trajectories) to general relativistic geodesics.
