Multifractality for intermediate quantum systems
Henrik Ueberschaer
While quantum multifractality has been widely studied in the physics literature and is by now well understood from the point of view of physics, there is little work on this subjec…
Multifractal eigenfunctions for a singular quantum billiard
Jonathan P. Keating, Henrik Ueberschaer
Whereas much work in the mathematical literature on quantum chaos has focused on phenomena such as quantum ergodicity and scarring, relatively little is known at the rigorous level…
Spectral geometry of flat tori with random impurities
Henrik Ueberschaer
We discuss new results on the geometry of eigenfunctions in disor- dered systems. More precisely, we study tori , , with uniformly distributed Dirac masses. Wherea…
Superscars in the Seba billiard
Henrik Ueberschaer, Par Kurlberg
We consider the Laplacian with a delta potential (a "point scatterer") on an irrational torus, where the square of the side ratio is diophantine. The eigenfunctions fall into two c…
