We report non-Hermitian energy level alignment via photon–phonon dressing quantization. propose a spectral homogenizer based on four types of alignment, revealing that the reverse effect induces this alignment.
We report the multi-Fano interference obtained through simultaneous acquisition of bright and dark states in different phase transitions Eu3+: BiPO4 (7:1, 6:1, 1:1, 0.5:1) NaYF4 (1:1/4) crystals. employ multi-dressed spontaneous four-wave mixing fluorescence (multi-order) to optimize strong photon-phonon nested dressing effect resulting more obvious interference.

Abstract Chiral imaging, which utilizes chiral nanostructures to produce grayscale images, has attracted significant attention due its potential for precise object and environmental perception. However, conventional imaging techniques primarily rely on external light sources other necessary optical components create desired patterns, are compatible with device integration miniaturization. In this study, a passive technique is presented by fully exploiting the spontaneous thermal emission of...
Abstract We study the Fano interference from different phase transitions of Eu 3+ :YPO 4 and Pr crystals through simultaneous detection bright dark states.

Further, between conti-nuous discrete can be controlled partly-(constructive–destructive)-interference a...

More phonon results in interaction, while less constructive coherences. experimental measurements agree with...
Abstract For the first time, Autler Townes‐splitting dependency on parity‐time symmetry breaking is investigated.

First‐order corresponds to pure crystal field attributed shifting energy levels inherent effect field. Second/third‐order results from coexistence non‐Hermitian Townes (SAT)‐splitting caused by single‐photon dressing coupled with...
