This study investigates the application technology of near-ultraviolet femtosecond laser pulse inscription inside polymethylpentene. We discovered that this thermoplastic material exhibits polarization-sensitive characteristics. First, inscription experiments employed a lens with a numerical apertur…

The introduction of non-Hermiticity extends concepts in traditional Hermitian quantum systems and induces many novel physical phenomena, such as the non-Hermitian skin effect unique to non-Hermitian systems, which has made the simulation of non-Hermitian quantum models a focus of attention. Compared…
