Dynamical Lifshitz Tails
Íris Emilsdóttir, Grigorii Monakov
We consider one-parameter families of random circle diffeomorphisms for which the unperturbed map has a fixed point of order and the dependence on th…

On the Kotani-Last Conjecture for the Dirac Operator
Nyah Davis, íris Emilsdóttir, Long Li +1
We prove a dichotomy of almost periodicity for reflectionless one-dimensional Dirac operators whose spectra satisfy certain geometric conditions, extending work of Volberg--Yuditsk…

The Schwartzman Group of an Affine Transformation
David Damanik, Íris Emilsdóttir, Jake Fillman
We compute the Schwartzman group associated with an ergodic affine automorphism of a compact connected abelian group given by the composition of an automorphism of the group and a…
