Origin of the Chemical Elements
This review provides the necessary background from astrophysics, nuclear, and particle physics to understand the cosmic origin of the chemical elements. It reflects the year 2009 state of the art in
Conformal structure in the spectrum of an altered quantum Ising chain
The Ising model with an infinite line of defects is mapped onto a strip with two defect lines. The Hamiltonian spectrum is studied at the bulk critical point. Its exact diagonal form is found for an
High energy neutrinos and photons from curvature pions in magnetars
We discuss the relevance of the curvature radiation of pions in strongly magnetized pulsars or magnetars, and their implications for the production of TeV energy neutrinos detectable by cubic
Resummation and Renormalization in Effective Theories of Particle Physics
Effective Theories From Nuclear to Particle Physics.- Finite Temperature Field Theories: Review.- Divergences in the Perturbation Theory.- Optimized Perturbation Theory.- The Large-N Expansion.-
Non-Gaussian fixed points in fermionic field theories without auxiliary Bose fields
The functional equation governing the renormalization flow of fermionic field theories is investigated in $$d$$d dimensions without introducing auxiliary Bose fields on the example of the Gross–Neveu
Local potential approximation for the renormalization group flow of fermionic field theories
The second functional derivative of the effective potential of pure fermionic field theories is rewritten in a factorized form which facilitates the evaluation of the renormalisation flow rate of the
Scalar mass stability bound in a simple Yukawa-theory from renormalization group equations
Functional renormalization group (FRG) equations are constructed for a simple Yukawa-model with discrete chiral symmetry, including also the effect of a nonzero composite fermion background beyond
