Securing public transportation systems: an integrated decision analysis framework for the prevention of terrorist attacks as example
No full textFlorian Brauner addresses the risk reduction effects of security measures (SecMe) as well as economic and social effects using terrorist threats in public transportation as use case. SecMe increase the level of security but cause interferences and restrictions for customers (e.g. privacy). This study identifies the interferences and analyzes the acceptance with an empirical survey of customers. A composite indicator for the acceptance of different SecMe is developed and integrated into a risk management framework for multi-criteria decision analysis achieving the right balance of risk reduction, costs, and social acceptance.

Spontaneous symmetry breaking and Nambu–Goldstone bosons in quantum many-body systems
No full textSpontaneous symmetry breaking is a general principle that constitutes the underlying concept of a vast number of physical phenomena ranging from ferromagnetism and superconductivity in condensed matter physics to the Higgs mechanism in the standard model of elementary particles. I focus on manifestations of spontaneously broken symmetries in systems that are not Lorentz invariant, which include both nonrelativistic systems as well as relativistic systems at nonzero density, providing a self-contained review of the properties of spontaneously broken symmetries specific to such theories. Topics covered include: (i) Introduction to the mathematics of spontaneous symmetry breaking and the Goldstone theorem. (ii) Minimization of Higgs-type potentials for higher-dimensional representations. (iii) Counting rules for Nambu–Goldstone bosons and their dispersion relations. (iv) Construction of effective Lagrangians. Specific examples in both relativistic and nonrelativistic physics are worked out in detail
