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…

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…

Topological Crystalline Phases in a Disordered Inversion-Symmetric Chain
Saavanth Velury, Barry Bradlyn, Taylor L. Hughes
When translational symmetry is broken by bulk disorder, the topological nature of states in topological crystalline systems may change depending on the type of disorder that is app…
