Typical Entanglement of Superpositions
Damien Quinn, Joshuah T. Heath, Graham Kells
We investigate universal entanglement properties inherent to superpositions of randomized states. We find that an -fold superposition of typical states may be classified into tw…
Mapping the non-equilibrium interacting Anderson Impurity Model to an effective Gaussian theory
Emmanuel Bogacz, Graham Kells, Andrew K. Mitchell
Quantum impurity models with strong electron correlations, such as the paradigmatic Anderson Impurity Model (AIM), are central to our understanding of a range of physical phenomena…
Measurement Induced Dynamics and Trace Preserving Replica Cutoffs
Graham Kells
We present a general methodology for addressing the infinite hierarchy problem that arises in measurement-induced dynamics of replicated quantum systems. Our approach introduces tr…
Topological fingerprints in Liouvillian gaps
Kevin Kavanagh, Joost K. Slingerland, Shane Dooley +1
Topology in many-body physics usually emerges as a feature of equilibrium quantum states. We show that topological fingerprints can also appear in the relaxation rates of open quan…
Data-Driven Time Propagation of Quantum Systems with Neural Networks
James Nelson, Luuk Coopmans, Graham Kells +1
We investigate the potential of supervised machine learning to propagate a quantum system in time. While Markovian dynamics can be learned easily, given a sufficient amount of data…
Extreme many-body scarring in a quantum spin chain via weak dynamical constraints
Shane Dooley, Graham Kells
It has recently been established that quantum many-body scarring can prevent the thermalisation of some isolated quantum systems, starting from certain initial states. One of the f…
