Symmetry and Topology in a Non-Hermitian Kitaev chain
Ayush Raj, Soham Ray, Sai Satyam Samal
We investigate the non-Hermitian Kitaev chain with non-reciprocal hopping amplitudes and asymmetric superconducting pairing. We work out the symmetry structure of the model and sho…
Autoregressive Adaptive Hypergraph Transformer for Skeleton-based Activity Recognition
Abhisek Ray, Ayush Raj, Maheshkumar H. Kolekar
Extracting multiscale contextual information and higher-order correlations among skeleton sequences using Graph Convolutional Networks (GCNs) alone is inadequate for effective acti…
Propagation of polarized gravitational waves
Lars Andersson, Jérémie Joudioux, Marius A. Oancea +1
The propagation of high-frequency gravitational waves can be analyzed using the geometrical optics approximation. In the case of large but finite frequencies, the geometrical optic…
