This book is the first monograph dedicated to the use of the total absorption technique in beta decay studies. It provides a detailed introduction to the beta decay process and all necessary know-how for the use of the total absorption technique.Total absorption spectroscopy (TAS) is the one of the very few techniques available that can provide nuclear decay data free from the Pandemonium effect (the systematic error causes the assignment of larger beta-decay probabilities than the...

The first non-electromagnetic messengers from space were discovered in the early 20th century, but it is only now that multimessenger astronomy is coming into its own. The aim of Multimessenger Astronomy in Practice is to aid an astronomer who is new to research in a particular area of multimessenger astronomy. Covering electromatic radiation from radio through to gamma-rays, and moving on to neutrino, cosmic-ray and gravitational wave astronomy, it gives the reader an overview of...

During more than 10 years, from 1989 until 2000, the LEP accelerator and the four LEP experiments, ALEPH, DELPHI, L3 and OPAL, have taken data for a large amount of measurements at the frontier of particle physics. The main outcome is a thorough and successful test of the Standard Model of electroweak interactions. Mass and width of the Z and W bosons were measured precisely, as well as the Z and photon couplings to fermions and the couplings among gauge bosons. The rst part of this work w...

This practical book presents an overview of the various approaches developed to understand the dynamics of electronic systems in physics and chemistry. It also illustrates typical application examples, namely atoms, molecules, and clusters such as nano objects. For each system, the book reviews its key features and concepts and also provides a wider perspective on other physical systems such as atomic nuclei and quantum dots.There exist a large number of theories adapted to specifi...

This book introduces various physical processes related to the formation and evolution of galaxies, such as gravitation, electromagnetism, statistical physics, condensed matter, non-equilibrium processes, and relativity. Real data are analyzed using statistical methods and theoretical understanding. These topics give students and researchers in other fields a cross-sectional, interdisciplinary review. In particular, the author puts a great emphasis on multi-wavelength observations and surv...

This book explores magnetic properties and critical temperatures in inverse ferrite Fe₃⁺(M₂⁺Fe₃⁺)O₄ spinels (e.g., Fe, Co, Ni). It calculates transition and Curie Weiss temperatures, providing insights into their thermodynamic behavior. Using the full potential linearized augmented plane wave (FP-LAPW) method, it investigates electrical and magnetic structures of spinel chromite, revealing magnetic moments in MnCr₂S₄. Seebeck coefficient and electrical conductivity are also calculated. Adv...

This book focuses on the most recent, relevant, comprehensive and significant aspects in the well-established multidisciplinary field Laboratory Astrophysics. It focuses on astrophysical environments, which include asteroids, comets, the interstellar medium, and circumstellar and circumplanetary regions. Its scope lies between physics and chemistry, since it explores physical properties of the gas, ice, and dust present in those systems, as well as chemical reactions occurring in the gas p...

This thesis addresses the feasibility of the production of ultra-high-energy cosmic rays in starburst galaxies and active galactic nuclei. These astrophysical objects were theoretically proposed as candidate sources a long time ago. Nevertheless, the interest in them has been recently renewed due to the observational data collected by the Pierre Auger Observatory and the Telescope Array. In this work, a comprehensive review of the current status of the research on cosmic rays accelerators ...

With a focus on modified gravity this book presents a review of the recent developments in the fields of gravity and cosmology, presenting the state of the art, high-lighting the open problems, and outlining the directions of future research.General Relativity and the ΛCDM framework are currently the standard lore and constitute the concordance paradigm of cosmology. Nevertheless, long-standing open theoretical issues, as well as possible new observational ones arising from the exp...

This thesis presents new insights into the strong interactions among electronic, lattice, spin, and orbital degrees of freedom in layered magnetic materials, as well as their emergent properties. Using a suite of spectroscopic techniques, both in equilibrium and out-of-equilibrium settings, several important findings have been made. In a family of transition metal thiophosphates, a novel bound state resulting from electronic transitions between d-orbitals and Raman-active phonons ...

Einstein's theory of general relativity is one of the pillars of modern physics and it is our standard framework for describing gravitational fields and the spacetime structure. So far, general relativity has passed all experimental tests and agrees with observations. However, the past few years have seen remarkable observational improvements and new techniques that continually challenge the theory's predictions: routinely detect the gravitational wave signals from the coalescence of black...

What are the physical mechanisms that underlie the efficient generation and transfer of energy at the nanoscale? Nature seems to know the answer to this question, having optimised the process of photosynthesis in plants over millions of years of evolution. It is conceivable that humans could mimic this process using synthetic materials, and organic semiconductors have attracted a lot of attention in this respect.Once an organic semiconductor absorbs light, bound pairs of electrons ...
