Long-range resonances in quasiperiodic many-body localization
Ashirbad Padhan, Jeanne Colbois, Fabien Alet +1
We investigate long-range resonances in quasiperiodic many-body localized (MBL) systems. Focusing on the Heisenberg chain in a deterministic Aubry-André potential, we complement s…
Variational study of the magnetization plateaus in the spin-1/2 kagome Heisenberg antiferromagnet: an approach from vision transformer neural quantum states
Andreas Raikos, Sylvain Capponi, Fabien Alet
We analyze the magnetization curve of the spin-1/2 kagome Heisenberg model in a magnetic field. Using state-of-the-art variational wavefunctions based on neural networks, we confir…
Beyond the imbalance: site-resolved dynamics probing resonances in many-body localization
Asmi Haldar, Thibault Scoquart, Fabien Alet +1
We explore the limitations of using imbalance dynamics as a diagnostic tool for many-body localization (MBL) and show that spatial averaging can mask important microscopic features…
Phase transitions and remnants of fractionalization at finite temperature in the triangular lattice quantum loop model
Xiaoxue Ran, Sylvain Capponi, Junchen Rong +2
The quantum loop and dimer models are archetypal correlated systems with local constraints. With natural foundations in statistical mechanics, they are of direct relevance to vario…
Detecting the Largest Correlations using the Correlation Density Matrix: a Quantum Monte Carlo Approach
Aditya Chincholi, Sylvain Capponi, Fabien Alet
We present a quantum Monte Carlo-based approach to detect and compute the most dominant correlations for many-body systems without prior knowledge. It is based on the measurement a…
Large deviations in the many-body localization transition: The case of the random-field XXZ chain
Greivin Alfaro Miranda, Fabien Alet, Giulio Biroli +3
The effect of rare system-wide resonances in the many-body localization (MBL) transition has recently attracted significant attention. They are expected to play a prominent role in…
