Many-Body Protection of Topological Edge Memory in Strong Interacting Quenches
Yuxiao Hang, Stephan Haas, Rishabh Jha
Quantum quenches drive edge states far from equilibrium, yet whether the memory of a topological initial state survives in a non-integrable, interacting system has remained largely…
Dynamics of Majorana Fermions on a Quantum Computer
Yuxiao Hang, Rosa Di Felice, Aiichiro Nakano +1
The study of quasiparticle dynamics is central to understanding non-equilibrium phenomena in quantum many-body systems. Direct simulation of such dynamics on quantum hardware has b…
Geometric Decoherence Time in Lindbladian Dynamics
Rishabh Jha, Stephan Haas, Abhinav Prem
The onset of decoherence in open many-body systems lacks a dynamical timescale grounded in the loss of bipartite entanglement. Here, we introduce the $tim…
Topological Phase Diagram of Generalized SSH Models with Interactions
Yuxiao Hang, Stephan Haas
We investigate interacting Su-Schrieffer-Heeger (SSH) chains with two- and three-site unit cells using density matrix renormalization group (DMRG) simulations. By selecting appropr…
