Synthetic SU(3) non-Abelian gauge fields in photonic synthetic frequency dimensions
Bengy Tsz Tsun Wong, Shu Yang, Zehai Pang +1
Synthetic gauge fields provide a powerful route to engineer photonic wave dynamics, especially in synthetic frequency dimensions formed by modulated resonator modes. While most pre…
Observation of Non-Hermitian Skin Dynamics in the Liouvillian Regime
Shu Yang, Yeyang Sun, Lingrui Hong +1
Open quantum systems generally do not perfectly preserve phase coherence: coupling to uncontrolled environments requires a density-matrix description based on the Liouvillian frame…
Observation of Floquet erratic non-Hermitian skin effect in photonic mesh lattice
Yeyang Sun, Shu Yang, Yi Yang
In ordered, translationally invariant non-Hermitian systems, the skin effect is understood as a boundary phenomenon: nonreciprocal hopping drives an extensive accumulation of eigen…
Non-Abelian Electric Field and Zitterbewegung on a Photonic Frequency Chain
Shu Yang, Bengy Tsz Tsun Wong, Yi Yang
The synthetic frequency dimension, which realizes fictitious spatial dimensions from the spectral degree of freedom, has emerged as a promising platform for engineering artificial…
Parity-time symmetry phase transition in photonic time-modulated media
Rui-Chuan Zhang, Shu Yang, Yixin Sha +2
Time modulation can cause gain and loss in photonic media, leading to complex modal behaviors and enhanced wave controllability in the non-Hermitian regime. Conversely, we reveal t…
Synthetic gain for electron-beam spectroscopy
Yongliang Chen, Kebo Zeng, Zetao Xie +9
Electron-beam microscopy and spectroscopy featuring atomic-scale spatial resolution have become essential tools used daily in almost all branches of nanoscale science and technolog…
Synthetic non-Abelian Electric Fields and Spin-Orbit Coupling in Photonic Synthetic Dimensions
Bengy Tsz Tsun Wong, Zehai Pang, Yi Yang
We theoretically propose a scheme to synthesize photonic non-Abelian electric field and spin-orbit coupling (SOC) in the synthetic frequency dimension based on a polarization-multi…
Broadband measurement of Feibelman's quantum surface response functions
Zeling Chen, Shu Yang, Zetao Xie +8
The Feibelman -parameter, a mesoscopic complement to the local bulk permittivity, describes quantum optical surface responses for interfaces, including nonlocality, spill-in and…
Second harmonic generation at a time-varying interface
Romain Tirole, Stefano Vezzoli, Dhruv Saxena +6
Time-varying metamaterials rely on large and fast changes of the linear permittivity. Beyond the linear terms, however, the effect of a non-perturbative modulation of the medium on…
