We discuss damping of the collective rotational motion in A ∼ 150 superdeformed nuclei by means of a shell model combining the cranked Nilsson mean-filed and the surface-delta two-body residual force. It is shown that, because of the shell structure associated with the superdeformed mean-field, onset energy of the rotational damping becomes Ex ∼ 2− 3 MeV above yrast line, which is much higher t...

The thermal evolution of the shell correction energy is investigated for deformed nuclei using Strutinsky prescription in a self-consistent relativistic mean-field framework. For temperature independent single-particle states corresponding to either spherical or deformed nuclear shapes, the shell correction energy ∆sc steadily washes out with temperature. However, for states pertaining to the s...

A framework is proposed that allows to write down field theories with a new energy scale while explicitly preserving Lorentz invariance and without spoiling the features of standard quantum field theory which allow quick calculations of scattering amplitudes. If the invariant energy is set to the Planck scale, these deformed field theories could serve to model quantum gravity phenomenology. The...

All consistent interactions in D=5 that can be added to a free model that describes a massless tensor field with the mixed symmetry (2,1) and an abelian BF theory with a maximal field spectrum are constructed by means of deforming the solution to the master equation on behalf of specific cohomological techniques. Under the hypotheses of analyticity in the coupling constant, spacetime locality, ...
