Diffusive metal in a percolating Chern insulator
Subrata Pachhal, Naba P. Nayak, Soumya Bera +1
Two-dimensional non-interacting fermions without any anti-unitary symmetries generically get Anderson localized in the presence of disorder. In contrast, topological superconductor…

Critical States of Fermions with Flux Disorder
Hiranmay Das, Naba P. Nayak, Soumya Bera +1
Motivated by many contemporary problems in condensed matter physics where matter particles experience random gauge fields, we investigate the physics of fermions on a square lattic…

Quantum Hall criticality in an amorphous Chern insulator
Soumya Bera, Johannes Dieplinger, Naba P Nayak
We explore the critical properties of a topological transition in a two-dimensional, amorphous lattice with randomly distributed points. The model intrinsically breaks the time-rev…
