Graph Bispectrum for Nonlinear Mode Interactions
Rahul Singh, Reza Abiri, Walter Besio
We introduce a graph bispectrum formulation for characterizing higher-order interactions in graph signals. While conventional graph spectral methods capture only second-order struc…

Emergent topological phase from a one-dimensional network of defects
Rahul Singh, Ritajit Kundu, Arijit Kundu +1
Symmetry-protected topological phases of matter, characterized by non-trivial band topology, are spectrally gapped and show non-trivial boundary phenomena. Here, we show that scatt…

Graph Fourier Transform based on Directed Laplacian
Rahul Singh, Abhishek Chakraborty, B. S. Manoj
In this paper, we redefine the Graph Fourier Transform (GFT) under the DSP framework. We consider the Jordan eigenvectors of the directed Laplacian as graph harmonics…
