Complex Hadamard matrices and the Spectral Set Conjecture
Mihail N. Kolountzakis, Mate Matolcsi
By analyzing the connection between complex Hadamard matrices and spectral sets we prove the direction ``spectral -> tile'' of the Sectral Set Conjecture for all sets A of size at…

Tiles with no spectra
Mihail N. Kolountzakis, Mate Matolcsi
We exhibit a subset of a finite Abelian group, which tiles the group by translation, and such that its tiling complements do not have a common spectrum (orthogonal basis for their…
