Mathematical basis, phase transitions and singularities of (3 1)-dimensional phi4 scalar field model

Abstract: The lambda phi4 scalar field model that can be applied to interpret pion-pion scattering and properties of hadrons. In this work, the mathematical basis, phase transitions and singularities of a (3 1)-dimensional (i.e., (3 1)D) phi4 scalar field model are investigated. It is found that as a specific example of topological quantum field theories, the (3 1)D phi4 scalar field model must be set up on the Jordan-von Neumann-Wigner framework and dealt with the parameter space of complex time (or complex temperature). The use of the time average and the topologic Lorentz transformation representing Reidemeister moves ensure the integrability, which takes into account for the contributions of nontrivial topological structures to physical properties of the many-body interacting system. The ergodic hypothesis is violated at finite temperatures in the (3 1)D phi4 scalar field model. Because the quantum field theories with ultraviolet cutoff can be mapped to the models in statistical mechanics, the (3 1)D phi4 scalar field model with ultraviolet cutoff is studied by inspecting its relation with the three-dimensional (3D) Ising model. Furthermore, the direct relation between the coupling K in the 3D Ising model and the bare coupling lambda0 in the (3 1)D phi4 scalar field model is determined in the strong coupling limit. The results obtained in the present work can be utilized to investigate thermodynamic physical properties and critical phenomena of quantum (scalar) field theories.

My controversial take on "AI" ray tracing helpers are that it's a really good idea.
First some background: keep in mind that machine learning tecnologies excell at tasks that have a high reward for success and a small cost for failure. In this case getting most of the rays right improve performance, at the cost of some few rays being shot in nothing.
Secondly, light rays are way too many in real life to be simulated in their entirety, so using some statistics to approximate the lighting model makes a lot of sense here. Plus at the lower quantum scale even phisicists use statistic to explain this stuff, so it's not that irrealistic either.
Finally the source data for this stuff is entirely other games, so ethically sourcing the training data set should not be a concern here.
Here, technology can be good or bad. It's not the tech, it's the use of the tech by the people (but that I mean oligarchic corporations) that makes them good or bad.
