Aspects of Information Theory in Curved Space
Achim Kempf
The often-asked question whether space-time is discrete or continuous may not be the right question to ask: Mathematically, it is possible that space-time possesses the differentia…
On the Vacuum Energy in Expanding Space-Times
Achim Kempf
If there is a shortest length in nature, for example at the Planck scale of 10^-35m, then the cosmic expansion should continually create new comoving modes. A priori, each of the n…
On Path Integration on Noncommutative Geometries
Achim Kempf
We discuss a recent approach to quantum field theoretical path integration on noncommutative geometries which imply UV/IR regularising finite minimal uncertainties in positions and…
Simple considerations on the behaviour of bosonic modes with quantum group symmetry
A. Kempf
While it is possible to introduce quantum group symmetry into the framework of quantum mechanics, the general problem of how to implement quantum group symmetry into dimens…
Approach to Quantum Group deformed Quantum Field Theory
Achim Kempf
In quantum field theory the creation and annihilation operators that are located at the points in 3-momentum space have commutation relations that are conserved under the action of…
Quantum Group Symmetric Bargmann Fock Construction
Achim Kempf
Usually in quantum mechanics the Heisenberg algebra is generated by operators of position and momentum. The algebra is then represented on an Hilbert space of square integrable fun…
