Fundamental physics in particle traps This volume provides detailed insight into the field of precision spectroscopy and fundamental physics with particles confined in traps. It comprises experiments with electrons and positrons protons and antiprotons antimatter and highly charged ions together with corresponding theoretical background. Such investigations represent stringent tests of quantum electrodynamics and the Standard model antiparticle and antimatter research test of fundamental symmetries constants and their possible variations with time and space. They are key to various aspects within metrology such as mass measurements and time standards as well as promising to further developments in quantum information processing. The reader obtains a valuable source of information suited for beginners and experts with an interest in fundamental studies using particle traps
