By using quantum computing and machine learning, they’ve begun to map the quantum state of a complex matrix model. This method, Rinaldi says, ...

A new model replaces the traditional reproduction number (R) with a reproduction matrix to better predict infectious disease spread by accounting for contact heterogeneity.

They analyzed the neutrino mass matrix by randomly assigning each element of the matrix. They showed theoretically, using the random mass matrix model that the lepton flavor mixings are large.

The ground-state energy E0 as a function of the cutoff for various couplings λ = g2 N = 0.2, 0.5, 1.0, and 2.0 for the SU(2) bosonic model. Even (E) and odd (O) values of are plotted with ...
