Localization of Dirac fermions in finite-temperature gauge theory

M Giordano, TG Kovács - Universe, 2021 - mdpi.com
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

P Corbae, JD Hannukainen, Q Marsal… - Europhysics …, 2023 - iopscience.iop.org
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

X Zhang, B Zhang, H Sahin, ZB Siu… - Communications …, 2023 - nature.com
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

S Kaur, T Chanda, KR Amin, D Sahani… - Nature …, 2024 - nature.com
Fractional quantum Hall (FQH) phases emerge due to strong electronic interactions and are
characterized by anyonic quasiparticles, each distinguished by unique topological …

Field theory of non-Hermitian disordered systems

Z Chen, K Kawabata, A Kulkarni, S Ryu - arxiv preprint arxiv:2411.11878, 2024 - arxiv.org
The interplay between non-Hermiticity and disorder gives rise to unique universality classes
of Anderson transitions. Here, we develop a field-theoretical description of non-Hermitian …
