Precision-Induced Irreversibility in non-Hermitian systems
Luis E. F. Foa Torres, G. Pappas, V. Achilleos +1
The paper investigates how finite numerical or experimental precision creates a predictability horizon in non‑Hermitian quantum systems, leading to precision‑induced irreversibilit…

Crossovers from nonlinear wave-packet acceleration to wave-mixing and self-trapping in the Hatano-Nelson model
Bertin Many Manda, Vassos Achilleos
We demonstrate that wave amplification enables even weak nonlinearities to reshape linear wave-packet transport in nonreciprocal systems. We study the dynamics of bulk Gaussian wav…

Universal critical timescales in slow non-Hermitian dynamics
Giorgos Pappas, Diego Bautista Avilés, Luis E. F. Foa Torres +1
Non-Hermitian systems driven along slow parametric loops undergo non-adiabatic transitions whose outcome depends sensitively on the driving speed, yet no explicit formula has been…
