Dynamically Generated Fermi Surface Mismatch and Relativistic Superfluidity in a Two-Component Massless Fermionic Theory
Susobhan Mandal, Sambuddha Sanyal
When fermions pair across mismatched Fermi surfaces, the mismatch reflects a built-in inequivalence between the species. We show it can instead arise dynamically by spontaneous sym…

Emergent Nonperturbative Universal Floquet Localization
Soumadip Pakrashi, Atanu Rajak, Sambuddha Sanyal
We show that a robust, nonperturbative localization plateau emerges in periodically driven quasiperiodic lattices, independent of the static localization properties and drive proto…
