Exact Temporal Criticalities of Entanglement and Negativity in Gaussian and Non-Gaussian Dissipative Kitaev Chains
Shrey Chowdhary, Sanket Chirame, Stephan Haas +1
When the two largest eigenvalues of an entanglement or negativity spectrum meet, the gap of the corresponding entanglement or negativity Hamiltonian closes while entropies stay smo…
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…
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…
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…
Hofstadter Butterflies in Topological Insulators
Larry Li, Marcin Abram, Abhinav Prem +1
In this chapter, we investigate the energy spectra as well as the bulk and surface states in a two-dimensional system composed of a coupled stack of one-dimensional dimerized chain…
