Higher-order topological insulators in synthetic dimensions
Avik Dutt, Momchil Minkov, Shanhui Fan
Conventional topological insulators support boundary states that have one dimension lower than the bulk system that hosts them, and these states are topologically protected due to…
-Symmetric Topological Edge-Gain Effect
Alex Y. Song, Xiao-Qi Sun, Avik Dutt +6
We demonstrate a non-Hermitian topological effect that is characterized by having complex eigenvalues only in the edge states of a topological material, despite the fact that the m…
Creating locally interacting Hamiltonians in the synthetic frequency dimension for photons
Luqi Yuan, Avik Dutt, Mingpu Qin +2
The recent emerging field of synthetic dimension in photonics offers a variety of opportunities for manipulating different internal degrees of freedom of photons such as the spectr…
A single photonic cavity with two independent physical synthetic dimensions
Avik Dutt, Qian Lin, Luqi Yuan +3
The concept of synthetic dimensions, which has enabled the study of higher-dimensional physics on lower-dimensional physical structures, has generated significant recent interest i…
Inverse-designed photonic circuits for fully passive, bias-free Kerr-based nonreciprocal transmission and routing
Ki Youl Yang, Jinhie Skarda, Michele Cotrufo +6
Nonreciprocal devices such as isolators and circulators are key enabling technologies for communication systems, both at microwave and optical frequencies. While nonreciprocal devi…
Experimental band structure spectroscopy along a synthetic dimension
Avik Dutt, Momchil Minkov, Qian Lin +3
In recent years there has been significant interest in the concepts of synthetic dimensions, where one couples the internal degrees of freedom of a particle to form higher-dimensio…
