Probing the Spacetime Structure of Entanglement in Monitored Quantum Circuits with Graph Neural Networks
Javad Vahedi, Stefan Kettemann
Global entanglement in quantum many-body systems is inherently nonlocal, raising the question of whether it can be inferred from local observations. We investigate this problem in…
Machine Learning the Strong Disorder Renormalization Group Method for Disordered Quantum Spin Chains
A. Ustyuzhanin, J. Vahedi, S. Kettemann
We train machine learning algorithms to infer the entanglement structure of disordered long-range interacting quantum spin chains by learning from the strong disorder renormalisati…
Strong Disorder Renormalization Group Method for Bond Disordered Antiferromagnetic Quantum Spin Chains with Long Range Interactions: Ground State Properties
Stefan Kettemann
We introduce and implement a reformulation of the strong disorder renormalization group method in real space, well suited to study bond disordered antiferromagnetic power law coupl…
Competition between Kondo Effect and RKKY Coupling
Stefan Kettemann
When magnetic moments are immersed into the Fermi sea of itinerant electrons, rich quantum physics emerges. This is relevant for a wide range of materials including heavy Fermion s…
Local versus global stability in dynamical systems with consecutive Hopf-Bifurcations
Philipp C. Böttcher, Benjamin Schäfer, Stefan Kettemann +2
Quantifying the stability of an equilibrium is central in the theory of dynamical systems as well as in engineering and control. A comprehensive picture must include the response t…
Entanglement Entropy Growth in Disordered Spin Chains with Tunable Range Interactions
Youcef Mohdeb, Javad Vahedi, Ravindra N. Bhatt +2
The non-equilibrium dynamics of disordered many-body quantum systems after a global quantum quench unveils important insights about the competition between interactions and disorde…
