   3. Mai 2024 · This may seem discouraging when attempting to formulate a quantum field theory of gravity without introducing new symmetry principles, for example supersymmetry, to remove additional free parameters. A loophole is provided by Kenneth Wilson’s modern understanding of renormalisation. Here, the basic idea is to organise quantum fluctuations ...

   13. Mai 2024 · And indeed, were you to take a quantum field theory class at a university somewhere or pick up a real quantum field theory textbook, they almost never do this. 0:39:31.8 SC: This thing that I just told you, assigning a complex number to every possible field configuration, that is a perfectly valid way of thinking about quantum field theory.

   3. Mai 2024 · We give a rigorous proof that in any free quantum field theory with a finite group global symmetry G, on a compact spatial manifold, at sufficiently high energy, the density of states ρα(E) for each irreducible representation α of G obeys a universal formula as conjectured by Harlow and Ooguri. We further prove that this continues to hold in a weakly coupled quantum field theory, given an ...

   20. Mai 2024 · quantum mechanics, science dealing with the behaviour of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents— electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons. These properties include the interactions ...

   3. Mai 2024 · From the mid-1980s, string theory set up a possible framework to approach quantum gravity using a ‘top-down’ approach. The effective field theory approach to strong forces drove the development of the ‘bottom-up’ perspective, culminating in the mid-1990s. Recently, physicists have started a new program called Swampland to overcome the ...

   15. Mai 2024 · The interaction terms. The unrestricted configuration space of string field theory is the subcomplex of the BRST complex of the closed ( super -) string, regarded as a ℕ - graded vector space with respect to the ghost number grading, on those elements Ψ that satisfy. We shall write 𝔤 for this graded vector space.
