Cosmology quantum field theory

Is quantum physics part of cosmology?
Cosmology is the study of the very large, while quantum physics is the study of the very small.
Cosmology is the branch of astronomy that studies the structures of the universe..
What is effective field theory in cosmology?
Effective field theory of large-scale structure.
The density fluctuations seeded during inflation can be observed through perturbations of the CMB and large-scale structure.
Large-scale structure is the distribution of matter on cosmological scales at low redshifts..
What is quantum cosmological theory?
Quantum cosmology is the attempt in theoretical physics to develop a quantum theory of the universe.
This approach attempts to answer open questions of classical physical cosmology, particularly those related to the first phases of the universe..
What is the concept of quantum field theory?
quantum field theory, body of physical principles combining the elements of quantum mechanics with those of relativity to explain the behaviour of subatomic particles and their interactions via a variety of force fields..
What is the cosmos quantum theory?

This approach attempts to answer open questions of classical physical cosmology, particularly those related to the first phases of the universe..

What is the quantum theory of the universe?
Quantum theory is the theoretical basis of modern physics that explains the nature and behavior of matter and energy on the atomic and subatomic level.
The nature and behavior of matter and energy at that level is sometimes referred to as quantum physics and quantum mechanics..
What is the theory of the quantum field?
In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics.
QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of quasiparticles..
N e i l s B o h r and M a x P l a n c k are credited with fathering quantum theory.
When German physicist Max Planck published his work on the effect of radiation on a black body he was able to illustrate how radiant energy are made up of particle-like components d믭 as "quanta".
QFT treats particles as excited states (also called quanta) of their underlying quantum fields, which are more fundamental than the particles.
The equation of motion of the particle is determined by minimization of the action computed for the Lagrangian, a functional of fields associated with the particle.

The Field Theory in Cosmology course will cover three related topics: quantum field theory and inflation, statistical field theory and large scale

This course introduces quantum field theory from scratch and then develops the theory of the quantum fluctuations of fields and particles. We will focus, in

Quantum field theory with a Lie group base manifold

Group field theory (GFT) is a quantum field theory in which the base manifold is taken to be a Lie group.
It is closely related to background independent quantum gravity approaches such as loop quantum gravity, the spin foam formalism and causal dynamical triangulation.
It can be shown that its perturbative expansion can be interpreted as spin foams and simplicial pseudo-manifolds (depending on the representation of the fields).
Thus, its partition function defines a non-perturbative sum over all simplicial topologies and geometries, giving a path integral formulation of quantum spacetime.

This is a list of quantum field theories.
The first few sections are organized according to their matter content, that is, the types of fields appearing in the theory.
This is just one of many ways to organize quantum field theories, but reflects the way the subject is taught pedagogically.
