Gradient-based optimal control of the non-Hermitian skin effect in optomechanical arrays
Juste Deuyekbe, Philippe Djorwé, A. -H. Abdel-Aty +3
In single-port non-Hermitian sensors the Petermann factor offsets susceptibility gains, imposing a strict resource bound on metrological precision. We test whether a multi-port geo…

Model-level synthetic-flux control of hyperchaos order and matched-resource sensing in dissipative optomechanics
Stella Rolande Mbokop Tchounda, Carolle Tchodimou, Philippe Djorwe +2
Within a normalized six-dimensional model of dissipative optomechanics (one cavity + two mechanical resonators), a synthetic-flux phase acts as a reproducible control…
