Systematic analysis of radiative symmetry breaking in models with extended scalar sector
Leonardo Chataignier, Tomislav Prokopec, Michael G. Schmidt +1
Radiative symmetry breaking (RSB) is a theoretically appealing framework for the generation of mass scales through quantum effects. It can be successfully implemented in models wit…
Single-scale Renormalisation Group Improvement of Multi-scale Effective Potentials
Leonardo Chataignier, Tomislav Prokopec, Michael G. Schmidt +1
We present a new method for renormalisation group improvement of the effective potential of a quantum field theory with an arbitrary number of scalar fields. The method amounts to…
Natural Inflation from 5D SUGRA and Low Reheat Temperature
Filipe Paccetti Correia, Michael G. Schmidt, Zurab Tavartkiladze
Motivated by recent cosmological observations of a possibly unsuppressed primordial tensor component of inflationary perturbations, we reanalyse in detail the 5D conformal SUGR…
An exact solution of the Dirac equation with CP violation
Tomislav Prokopec, Michael G. Schmidt, Jan Weenink
We consider Yukawa theory in which the fermion mass is induced by a Higgs like scalar. In our model the fermion mass exhibits a temporal dependence, which naturally occurs in the e…
The Gaussian entropy of fermionic systems
Tomislav Prokopec, Michael G. Schmidt, Jan Weenink
We consider the entropy and decoherence in fermionic quantum systems. By making a Gaussian Ansatz for the density operator of a collection of fermions we study statistical 2-point…
The neutron and its role in cosmology and particle physics
Dirk Dubbers, Michael G. Schmidt
Experiments with cold and ultracold neutrons have reached a level of precision such that problems far beyond the scale of the present Standard Model of particle physics become acce…
