Chiral Transport Phenomena and Compact Stars

Hypernuclear Physics and Compact Stars

Hypernuclear physics plays a decisive role for several features of compact star physics. I review the impact of hypernuclear potential depths, two-body hyperon-nucleon and hyperon three-body forces as well as hyperon-hyperon interactions on the maximum mass, the mass-radius relation, and cooling properties of neutron stars. PACS. 21.80.+a Hypernuclei – 26.60.+c Nuclear matter aspects of neutron...

Numerical Simulation of Transport Phenomena in Nuclear Cores

Chiral phenomena in toroidal metamaterials

We present the first observation of circular dichroism due to a combination of resonant toroidal dipole and electric quadrupole excitations in a toroidal metamaterial.

Transport Phenomena and Light Element Abundances in the Sun and Solar Type Stars

The observations of light elements in the Sun and Solar type stars give special clues for understanding the hydrodynamical processes at work in stellar interiors. In the Sun Li is depleted by 140 while He has not increased by more than ∼= 10% in 3 Gyrs. Meanwhile the inversion of helioseismic modes lead to a precision on the sound velocity of about .1%. The mixing processes below the solar conv...

Interference Phenomena, Chiral Bosons and Lorentz Invariance

The concept of interference phenomena in quantum field theory is an analogy with Young's double slit experiment. It has been studied over the last few years, in various dimensions, in the light of the soldering formalism introduced by Stone to fusion two opposite manifestations of chirality. Firstly, we have studied the theory of gauged chiral bosons and proposed a new general theory that encom...
