Fragile Topology is Unstable Under Translation Refinement
Yoonseok Hwang, Saavanth Velury, Taylor L. Hughes
Fragile topological phases become trivial upon the addition of suitable trivial bands, distinguishing them from stable topological phases. Nevertheless, various response phenomena…

Global and Local Topological Crystalline Markers for Rotation-Symmetric Insulators
Saavanth Velury, Yoonseok Hwang, Taylor L. Hughes
Crystalline symmetry can be used to predict bulk and surface properties of topological phases. For non-interacting cases, symmetry-eigenvalue analysis of Bloch states at high symme…

Quasiparticle Variational Quantum Eigensolver
Saavanth Velury, Yuxuan Wang
We propose a momentum-space based variational quantum eigensolver (VQE) framework for simulating quasiparticle excitations in interacting quantum many-body systems on near-term qua…
