This thesis develops a new theory combining the beam-plasma instability and IGMF in one picture. Recently, it was observed that the expected cascade emission of gamma rays in the TeV range from some distant blazars is not seen in their spectra. The underlying physical processes are well known, and a failure of the model predictions would shake the foundations of modern physics unless a credible explanation for this failure is found. One could argue that a femto-Gauss strong magnetic field in the cosmic voids would disperse the cascade emission, although the question remains as to how...

This book outlines past and new developments in molecular response theory in terms of static and dynamic-induced current densities and showcases an important step forward in the field of molecular density functions and their topological analysis.  The book begins with a general perspective on topics such as classical Hamiltonian, quantum mechanical Hamiltonian, and topological analysis of the electron charge density, followed by an in-depth overview of time-dependent and -independent perturbations, and applications.

In this book, the author presents a completely new approach...

This book contains peer-reviewed contributions based on talks presented at the 25th International Workshop on Quantum Systems in Chemistry, Physics, and Biology held in Toruń, Poland, in June 2022. The book reviews significant advances in concepts, methods, and applications of quantum systems in a broad variety of areas in modern chemistry, physics, and biology. In particular, it discusses atomic, molecular, and solid state structure, dynamics and spectroscopy, relativistic and correlation effects in quantum chemistry, topics of computational chemistry, physics, and biology, as well as...

This book provides an introduction to noncommutative geometry and presents a number of its recent applications to particle physics. In the first part, we introduce the main concepts and techniques by studying finite noncommutative spaces, providing a "light" approach to noncommutative geometry. We then proceed with the general framework by defining and analyzing noncommutative spin manifolds and deriving some main results on them, such as the local index formula. In the second part, we show how noncommutative spin manifolds naturally give rise to gauge theories, applying this principle to...
