Localization of Dirac fermions in finite-temperature gauge theory
It is by now well established that Dirac fermions coupled to non-Abelian gauge theories can
undergo an Anderson-type localization transition. This transition affects eigenmodes in the …

Amorphous topological matter: Theory and experiment
Topological phases of matter are ubiquitous in crystals, but less is known about their
existence in amorphous systems, that lack long-range order. We review the recent progress …

Anomalous fractal scaling in two-dimensional electric networks
Much of the qualitative nature of physical systems can be predicted from the way it scales
with system size. Contrary to the continuum expectation, we observe a profound deviation …

Universality of quantum phase transitions in the integer and fractional quantum Hall regimes
Fractional quantum Hall (FQH) phases emerge due to strong electronic interactions and are
characterized by anyonic quasiparticles, each distinguished by unique topological …
