Topological Dissipative Photonics and Topological Insulator Lasers in Synthetic Time-Frequency Dimensions
Zhaohui Dong, Xianfeng Chen, Avik Dutt +1
The study of dissipative systems has attracted great attention, as dissipation engineering has become an important candidate towards manipulating light in classical and quantum way…
Creating boundaries along a synthetic frequency dimension
Avik Dutt, Luqi Yuan, Ki Youl Yang +4
Synthetic dimensions have garnered widespread interest for implementing high dimensional classical and quantum dynamics on lower dimensional geometries. Synthetic frequency dimensi…
-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…
Measuring invariants in dimer models and cross-coupled ladders with a programmable photonic molecule
Sashank Kaushik Sridhar, Rohith Srikanth, Alexander R. Miller +2
Topological models are characterized by a quantized topological invariant and provide a description of novel phases of matter that can exhibit localized edge states, corner modes,…
Experimental demonstration of dynamical input isolation in nonadiabatically modulated photonic cavities
Avik Dutt, Momchil Minkov, Qian Lin +3
Modulated optical cavities have been proposed and demonstrated for applications in communications, laser frequency stabilization, microwave-to-optical conversion and frequency comb…
Smooth double barriers in quantum mechanics
Avik Dutt, Sayan Kar
Quantum mechanical tunneling across smooth double barrier potentials modeled using Gaussian functions, is analyzed numerically and by using the WKB approximation. The transmission…
