Dark Energy
Norbert Straumann
After some remarks about the history and the mystery of the vacuum energy I shall review the current evidence for a cosmologically significant nearly homogeneous exotic energy dens…
The history of the cosmological constant problem
Norbert Straumann
The interesting early history of the cosmological term is reviewed, beginning with its introduction by Einstein in 1917 and ending with two papers of Zel'dovich, shortly before the…
On Pauli's invention of non-abelian Kaluza-Klein Theory in 1953
N. Straumann
There are documents which show that Wolfgang Pauli developed in 1953 the first consistent generalization of the five-dimensional theory of Kaluza, Klein, Fock and others to a highe…
Internal structure of Einstein-Yang-Mills-Dilaton black holes
O. Sarbach, N. Straumann, M. S. Volkov
We study the interior structure of the Einstein-Yang-Mills-Dilaton black holes as a function of the dilaton coupling constant . For the solutions have no inte…
On Newton-Cartan Cosmology
Christian Rueede, Norbert Straumann
After a brief summary of the Newton-Cartan theory in a form which emphasizes its close analogy to general relativity, we illustrate the theory with selective applications in cosmol…
Instability Proof for Einstein-Yang-Mills Solitons with Arbitrary Gauge Groups
Othmar Brodbeck, Norbert Straumann
We prove that static, spherically symmetric, asymptotically flat, regular solutions of the Einstein-Yang-Mills equations are unstable for arbitrary gauge groups, at least for the `…
