Experimental observation of energy-band Riemann surface
Dali Cheng, Heming Wang, Janet Zhong +3
Non-Hermiticity naturally arises in many physical systems that exchange energy with their environment. The presence of non-Hermiticity leads to many novel topological physics pheno…
Creating high-dimensional topological physics using a single ring resonator
Dali Cheng, Heming Wang, Charles Roques-Carmes +2
In spaces of three or more dimensions, there exists topological physics of significant richness that has no lower-dimensional counterparts. To experimentally explore high-dimension…
Non-Abelian lattice gauge fields in the photonic synthetic frequency dimension
Dali Cheng, Kai Wang, Charles Roques-Carmes +4
Non-Abelian gauge fields provide a conceptual framework for the description of particles having spins. The theoretical importance of non-Abelian gauge fields motivates their experi…
Eigenenergy braids in 2D photonic crystals
Janet Zhong, Charles C. Wojcik, Dali Cheng +1
We consider non-Hermitian energy band theory in two-dimensional systems, and study eigenenergy braids on slices in the two-dimensional Brillouin zone. We show the consequences of r…
Multi-dimensional band structure spectroscopy in the synthetic frequency dimension
Dali Cheng, Eran Lustig, Kai Wang +1
The concept of synthetic dimensions in photonics provides a versatile platform in exploring multi-dimensional physics. Many of these physics are characterized by band structures in…
Artificial non-Abelian lattice gauge fields for photons in the synthetic frequency dimension
Dali Cheng, Kai Wang, Shanhui Fan
Non-Abelian gauge fields give rise to nontrivial topological physics. Here we develop a scheme to create an arbitrary SU(2) lattice gauge field for photons in the synthetic frequen…
Quasi-edge states and topological Bloch oscillation in the synthetic space
Xiaoxiong Wu, Luojia Wang, Guangzhen Li +6
In physics, synthetic dimensions trigger great interest to manipulate light in different ways, while in technology, lithium niobate shows important capability towards on-chip appli…
Arbitrary synthetic dimensions via multi-boson dynamics on a one-dimensional lattice
Dali Cheng, Bo Peng, Da-Wei Wang +3
The synthetic dimension, a research topic of both fundamental significance and practical applications, is attracting increasing attention in recent years. In this paper, we propose…
Optical neural network architecture for deep learning with the temporal synthetic dimension
Bo Peng, Shuo Yan, Dali Cheng +5
The physical concept of synthetic dimensions has recently been introduced into optics. The fundamental physics and applications are not yet fully understood, and this report explor…
