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…

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…

Towards a Comprehensive Theory of Metal-Insulator Transitions in Doped Semiconductors

S. Kettemann

A review is given on the theory of metal-insulator transitions (MIT) in doped semiconductors. We focus in particular on reviewing theories of their anomalous magnetic properties, w…

Quantum Fidelity of the Aubry-André Model and the Exponential Orthogonality Catastrophe

Javad Vahedi, Stefan Kettemann

We consider the orthogonality catastrophe in the (extended) Aubry-André (AA)-Model, by calculating the overlap between the ground state of the Fermi liquid in that quasi-crysta…
