Hundreds of millions supermassive black hole binaries are expected to contribute the gravitational-wave signal in nanohertz frequency band. Their is often approximated either as an isotropic Gaussian stochastic background with a power-law spectrum, or individual source corresponding brightest binary. In reality, best described combination and few modeled individually. We present method that use...

We propose a local model for general fermionic systems, which we express in the Heisenberg picture. To this end, shall use recently proposed formalism, so-called “Raymond-Robichaud” construction, allows one to construct an explicitly any dynamical theory that satisfies no-signaling, terms of equivalence classes transformations can be attached each individual subsystem. By following rigorous par...
