Eight-fold classification of superconducting orders
Alexander V. Balatsky, Saikat Banerjee
We present a symmetry-based classification for superconducting pairing states, organized by the exchange properties of the anomalous correlation function rather than by a specific…

Gradient-based optimization for variational empirical Bayes multiple regression
Saikat Banerjee, Peter Carbonetto, Matthew Stephens
Variational empirical Bayes (VEB) methods provide a practically attractive approach to fitting large, sparse, multiple regression models. These methods usually use coordinate ascen…

Higher-order topological corner and bond-localized modes in magnonic insulators
Sayak Bhowmik, Saikat Banerjee, Arijit Saha
We theoretically investigate a two-dimensional decorated honeycomb lattice framework to realize a second-order topological magnon insulator (SOTMI) phase featuring distinct corner-…
