Abstract: Summary form only given. Early was proposed new types of basis functions for variational calculations of the quantum-mechanical systems with Coulomb interaction between the particles. This ...

This study investigates the decomposition of bath correlation functions (BCFs) in terms of complex exponential functions, with an eye on the realistic modeling of open quantum systems based on the ...

The discrete Fourier transforms of the six families of E-functions of the groups O(5) and G(2) is summarized. The six types are shown to be generalizations of the Euler formula for the complex ...
