Anomalous thermal relaxation and pump-probe spectroscopy of 2D topologically ordered systems
Max McGinley, Michele Fava, S. A. Parameswaran
We study the behaviour of linear and nonlinear spectroscopic quantities in two-dimensional topologically ordered systems, which host anyonic excitations exhibiting fractional stati…
Purification Dynamics in a Continuous-time Hybrid Quantum Circuit Model
Sebastian Leontica, Max McGinley
We introduce a continuous time model of many-body quantum dynamics based on infinitesimal random unitary operations, combined with projective measurements. We consider purification…
Shadow tomography from emergent state designs in analog quantum simulators
Max McGinley, Michele Fava
We introduce a method that allows one to infer many properties of a quantum state -- including nonlinear functions such as Rényi entropies -- using only global control over the con…
Signatures of fractional statistics in nonlinear pump-probe spectroscopy
Max McGinley, Michele Fava, S. A. Parameswaran
We show that the presence of anyons in the excitation spectrum of a two-dimensional system can be inferred from nonlinear spectroscopic quantities. In particular, we consider pump-…
Quantifying information scrambling via Classical Shadow Tomography on Programmable Quantum Simulators
Max McGinley, Sebastian Leontica, Samuel J. Garratt +2
We develop techniques to probe the dynamics of quantum information, and implement them experimentally on an IBM superconducting quantum processor. Our protocols adapt shadow tomogr…
Absolutely Stable Spatiotemporal Order in Noisy Quantum Systems
Max McGinley, Sthitadhi Roy, S. A. Parameswaran
We introduce a model of non-unitary quantum dynamics that exhibits infinitely long-lived discrete spatiotemporal order robust against any unitary or dissipative perturbation. Ergod…
Kramers' degeneracy for open systems in thermal equilibrium
Simon Lieu, Max McGinley, Oles Shtanko +2
Kramers' degeneracy theorem underpins many interesting effects in quantum systems with time-reversal symmetry. We show that the generator of dynamics for Markovian open fermionic s…
Elastic backscattering of quantum spin Hall edge modes from Coulomb interactions with non-magnetic impurities
Max McGinley, Nigel R. Cooper
We demonstrate that electrostatic interactions between helical electrons at the edge of a quantum spin Hall insulator and a dynamical impurity can induce quasi-elastic backscatteri…
Fragility of Time-Reversal Symmetry Protected Topological Phases
Max McGinley, Nigel R. Cooper
The second law of thermodynamics points to the existence of an `arrow of time', along which entropy only increases. This arises despite the time-reversal symmetry (TRS) of the micr…
Tenfold Way for Quadratic Lindbladians
Simon Lieu, Max McGinley, Nigel R. Cooper
We uncover a topological classification applicable to open fermionic systems governed by a general class of Lindblad master equations. These `quadratic Lindbladians' can be capture…
Interacting Symmetry-Protected Topological Phases Out of Equilibrium
Max McGinley, Nigel R. Cooper
The topological features of quantum many-body wave functions are known to have profound consequences for the physics of ground-states and their low-energy excitations. We describe…
Classification of topological insulators and superconductors out of equilibrium
Max McGinley, Nigel R. Cooper
We establish the existence of a topological classification of many-particle quantum systems undergoing unitary time evolution. The classification naturally inherits phenomenology f…
Slow growth of out-of-time-order correlators and entanglement in integrable disordered systems
Max McGinley, Andreas Nunnenkamp, Johannes Knolle
We investigate how information spreads in three paradigmatic one-dimensional models with spatial disorder. The models we consider are unitarily related to a system of free fermions…
Topology of one dimensional quantum systems out of equilibrium
Max McGinley, Nigel R. Cooper
We study the topological properties of one dimensional systems undergoing unitary time evolution. We show that symmetries possessed both by the initial wavefunction and by the Hami…
Robustness of Majorana edge modes and topological order -- exact results for the symmetric interacting Kitaev chain with disorder
Max McGinley, Johannes Knolle, Andreas Nunnenkamp
We investigate the robustness of Majorana edge modes under disorder and interactions. We exploit a recently found mapping of the interacting Kitaev chain in the symmetric region ($…
