Finite and disordered Kitaev chains: a large deviation study
Clément Fortin, Kai Wang, Tami Pereg-Barnea
Topological edge states are celebrated for their robustness against disorder, yet the interplay between disorder and system size remains poorly understood. We use large deviations…

Unifying Anderson transitions and topological amplification in non-Hermitian chains
Clément Fortin, Kai Wang, T. Pereg-Barnea
Non-Hermitian systems with non-reciprocal hopping may display the non-Hermitian skin effect, where states under open boundary conditions localize exponentially at one edge of the s…

Topological Amplification of the Bosonic Kitaev Chain with Non-Uniform Loss
Clément Fortin, Kai Wang, T. Pereg-Barnea
The bosonic Kitaev chain is known to have extraordinary properties distinct from its fermionic counterpart. For example, it exhibits the non-Hermitian skin effect -- its eigenmodes…
