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…
Nonlinear Dissipation and Hopf Criticality in Driven Dissipative Collective Spins
Shu Yang, Jun Wang, Weidong Li +3
Self-sustained oscillations combine finite-amplitude stabilization with a neutral phase degree of freedom. We develop this bifurcation-based framework for driven-dissipative collec…
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-Resonant Boundary Time Crystals from Quantum Synchronization Breakdown
Jun Wang, Shu Yang, Zeqing Wang +4
Quantum synchronization (QS) in dissipative systems is often inferred from smooth phase locking, leaving open whether its breakdown constitutes a genuine nonequilibrium transition.…
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…
Emergent Continuous Time Crystal in Dissipative Quantum Spin System without Driving
Shu Yang, Zeqing Wang, Libin Fu +1
Time crystals are a nonequilibrium phase of matter that extend fundamental spontaneous symmetry breaking into the temporal dimension, typically requiring external driving for their…
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…
Laser Manipulation of Spin-Exchange Interaction Between Alkaline-Earth Atoms in S and P States
Shu Yang, Yue Chen, Peng Zhang
Ultracold gases of fermionic alkaline-earth (like) atoms are hopeful candidates for the quantum simulation of many-body physics induced by magnetic impurities (e.g., the Kondo phys…
Two-body bound state of ultracold Fermi atoms with two-dimensional spin-orbit coupling
Shu Yang, Fan Wu, Wei Yi +1
In a recent experiment, a two-dimensional spin-orbit coupling (SOC) was realized for fermions in the continuum [Nat. Phys. 12, 540 (2016)], which represents an important step forwa…
