The Transplanckian Question and the Casimir Effect
S. Bachmann, A. Kempf
It is known that, through inflation, Planck scale phenomena should have left an imprint in the cosmic microwave background. The magnitude of this imprint is expected to be suppress…
Minimum Length Cutoff in Inflation and Uniqueness of the Action
A. Ashoorioon, A. Kempf, R. B. Mann
According to most inflationary models, fluctuations that are of cosmological size today started out much smaller than any plausible cutoff length such as the string or Planck lengt…
On Symmetric Operators in Noncommutative Geometry
A. Kempf
In Noncommutative Geometry, as in quantum theory, classically real variables are assumed to correspond to self-adjoint operators. We consider the relaxation of the requirement of s…
On the Structure of Space-Time at the Planck Scale
A. Kempf
The set of space-time short-distance structures which can be described through linear operators is limited to a few basic cases. These are continua, lattices and a further short-di…
Recent results on UV-regularisation through UV-modified uncertainty relations
A. Kempf
Assume that in a fundamental theory of quantum gravity spatial information is encoded through elements x_i of an associative, complex and possibly noncommutative algebra in which t…
