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…
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…
Entanglement flow in the Kane-Fisher quantum impurity problem
Chunyu Tan, Yuxiao Hang, Stephan Haas +1
The problem of a local impurity in a Luttinger liquid, just like the anisotropic Kondo problem (of which it is technically a cousin), describes many different physical systems. As…
