Quantum Cosmology and the Arrow of Time
Claus Kiefer
Although most fundamental laws are invariant under time reversal, experience exhibits the presence of irreversible phenomena -- the arrows of time. Their origin lies in cosmology,…
Will LIGO see RIGO's? - Radion-induced graviton oscillations in the two-brane world
Andrei O. Barvinsky, Alexander Yu. Kamenshchik, Claus Kiefer +1
One of the most interesting features of braneworld models is the existence of massive gravitational modes in addition to the usual massless one. Mixing of the modes which depends n…
On the interpretation of quantum theory - from Copenhagen to the present day
Claus Kiefer
A central feature in the Copenhagen interpretation is the use of classical concepts from the outset. Modern developments show, however, that the emergence of classical properties c…
Quantum aspects of black holes
Claus Kiefer
This is a brief introduction to quantum aspects of black holes, addressed at an astrophysics-oriented audience. The topics are: The laws of black-hole mechanics, Hawking radiation,…
Conceptual issues in quantum cosmology
Claus Kiefer
I give a review of the conceptual issues that arise in theories of quantum cosmology. I start by emphasising some features of ordinary quantum theory that also play a crucial role…
Wigner function and decoherence
C. Kiefer
I briefly review the role of the Wigner function in the study of the quantum-to-classical transition through interaction with the environment (decoherence).
