Genus-protected higher-order topological phases
Shahroze Shahab, Hui Liu, Daniel Varjas +1
Higher-order topological phases (HOTPs) feature protected gapless modes on boundaries of higher codimension, such as the corners or hinges of a crystal. They are understood as bein…

Topological boundaries in non-Hermitian p-wave Kitaev chains with Rashba spin-orbit coupling
Shahroze Shahab, Aditi Chakrabarty, Sanjoy Datta
In this work, we investigate the combined effects of Rashba spin-orbit coupling (RSOC) and non-Hermiticity on topological phase transitions in spinful p-wave Kitaev chains. While p…

Controlling Dissipative Topology Through Floquet Driving: From Transient Diagnostics to Boundary States Isolation
Koustav Roy, Shahroze Shahab, Saurabh Basu
Engineering dissipative dynamics in open quantum systems is under active focus, especially in topological settings where resilient edge modes are expected to exhibit decay rates di…
