AE Seminar

VPG Laserone, a successor of IRE-Polus Ltd founded in 1991 by physicist Valentin P. Gapontsev, represents over three decades of scientific leadership in high-power fiber laser technology. The company has established a vertically integrated manufacturing ecosystem in Russia—localizing 85 % of component production and dedicating 25 % of its investments to R&D—to design, develop, and […]

Non-Hermitian wave dynamics challenge our conventional understanding of wave propagation, revealing transport behaviors inaccessible in Hermitian systems. In this seminar, I will present a few intriguing phenomena arising from these dynamics. In the first part, I will show a counterintuitive tunneling effect at the interface of a non-Hermitian system sandwiched between two Hermitian ones. Here, […]
