Exceptional-point braiding with native controls
Vishnu Chavva, Nero Osmancevic, Hugo Ribeiro
Exceptional points define branch-exchange state transfers through holomorphic continuation of non-Hermitian eigenmodes, but realizing these transfers dynamically remains difficult.…

Topological Operations Around Exceptional Points via Shortcuts to Adiabaticity
Vishnu Chavva, Hugo Ribeiro
The existence of singularities in the spectrum of non-Hermitian Hamiltonians leads to a non-trivial spectral topology which can be exploited to generate topological operations. How…
