What are quantum dynamics?
In physics, quantum dynamics is the quantum version of classical dynamics. Quantum dynamics deals with the motions, and energy and momentum exchanges of systems whose behavior is governed by the laws of quantum mechanics. Quantum dynamics is relevant for burgeoning fields, such as quantum computing and atomic optics.
When was the quantum mechanical model created?
1926
In 1926 Erwin Schrödinger, an Austrian physicist, took the Bohr atom model one step further. Schrödinger used mathematical equations to describe the likelihood of finding an electron in a certain position. This atomic model is known as the quantum mechanical model of the atom.
What is quantum holonomy theory?
The theory is based on a C*-algebra that involves holonomy-diffeomorphisms on a 3-dimensional manifold and which encodes the canonical commutation relations of canonical quantum gravity formulated in terms of Ashtekar variables. …
Who created supersymmetry?
Supersymmetry or SUSY, developed in the early 1970s at the European Center for Nuclear Research (CERN) in Geneva, Switzerland, by Zumino and Julius Wess, was conceived to explain particle interactions involving three of the four main forces in nature – the strong, electromagnetic and weak forces.
What is supersymmetry and supergravity?
supergravity, a type of quantum field theory of elementary subatomic particles and their interactions that is based on the particle symmetry known as supersymmetry and that naturally includes the gravitational force along with the other fundamental interactions of matter—the electromagnetic force, the weak force, and …
What is quantum gravity?
Updated March 21, 2018 Quantum gravity is an overall term for theories that attempt to unify gravity with the other fundamental forces of physics (which are already unified together). It generally posits a theoretical entity, a graviton, which is a virtual particle that mediates the gravitational force.
What are the 4 types of quantum gravity theories?
Some unified field theories that are classified as quantum gravity theories include: String theory / Superstring theory / M-theory. Supergravity. Loop quantum gravity. Twistor theory. Noncommutative geometry. Euclidean quantum gravity.
Is there a quantum field theory for the gravitational force?
General relativity, like electromagnetism, is a classical field theory. One might expect that, as with electromagnetism, the gravitational force should also have a corresponding quantum field theory .
What is M-theory and loop quantum gravity?
The field of quantum gravity is actively developing, and theorists are exploring a variety of approaches to the problem of quantum gravity, the most popular being M-theory and loop quantum gravity. All of these approaches aim to describe the quantum behavior of the gravitational field.
