Inertial Frame Dragging and Relative Rotation of ZAMOs in Axistationary Asymptotically Flat Spacetimes
S. Braeck
In axistationary asymptotically flat spacetimes zero angular momentum observers (ZAMOs) define an absolute standard of non--rotation locally, as can be verified by the absence of a…
A non-relativistic Dirac equation: An application to photo ionization of highly charged hydrogen-like ions
Tor Kjellsson Lindblom, Simen Bræck, Sølve Selstø
We investigate the role of relativity in photo ionization of hydrogen-like ions by a laser pulse. For hydrogen, the wavelengths of the laser resides in the weakly ultra violet regi…
The Cosmic Causal Mass
S. Braeck, Ø. Grøn, I. Farup
In order to provide a better understanding of rotating universe models, and in particular the Gödel universe, we discuss the relationship between cosmic rotation and perfect inerti…
A physical interpretation of Hubble's law and the cosmological redshift from the perspective of a static observer
Simen Braeck, Oystein Elgaroy
We derive explicit and exact expressions for the physical velocity of a free particle comoving with the Hubble flow as measured by a static observer, and for the frequency shift of…
A river model of space
S. Braeck, O. Gron
Within the theory of general relativity gravitational phenomena are usually attributed to the curvature of four-dimensional spacetime. In this context we are often confronted with…
Spontaneous thermal runaway as an ultimate failure mechanism of materials
S. Braeck, Y. Y. Podladchikov
The first theoretical estimate of the shear strength of a perfect crystal was given by Frenkel [Z. Phys. 37, 572 (1926)]. He assumed that as slip occurred, two rigid atomic rows in…
