The quantum Ising chain with a generalized defect
Uwe Grimm
The finite-size scaling properties of the quantum Ising chain with different types of generalized defects are studied. These not only mean an alteration of the coupling constant as…
On the Entropy and Letter Frequencies of Ternary Square-Free Words
Christoph Richard, Uwe Grimm
We enumerate all ternary length-l square-free words, which are words avoiding squares of words up to length l, for l<=24. We analyse the singular behaviour of the corresponding gen…
A maximum principle for the mutation-selection equilibrium of nucleotide sequences
Tini Garske, Uwe Grimm
We study the equilibrium behaviour of a deterministic four-state mutation-selection model as a model for the evolution of a population of nucleotide sequences in sequence space. Th…
Bravais colourings of planar modules with N-fold symmetry
Michael Baake, Uwe Grimm
The first step in investigating colour symmetries for periodic and aperiodic systems is the determination of all colouring schemes that are compatible with the symmetry group of th…
