Dynamical Behaviour of Density Correlations Across the Chaotic Phase for Interacting Bosons
Ãscar Dueñas, Alberto RodrÃguez
We investigate the propagation of two-point density correlations in the one-dimensional Bose-Hubbard Hamiltonian in the thermodynamic limit in terms of the correlation transport di…
Putting machine learning to the test in a quantum many-body system
Yilun Gao, Alberto RodrÃguez, Rudolf A. Römer
Quantum many-body systems pose a formidable computational challenge due to the exponential growth of their Hilbert space. While machine learning (ML) has shown promise as an altern…
Characterization of the chaotic phase in the tilted Bose-Hubbard model
Pilar MartÃn Clavero, Alberto RodrÃguez
The chaotic phase of the tilted Bose-Hubbard model is identified as a function of energy, tilt strength and particle interaction, from the eigenstate structure and the statistical…
Many-body interference at the onset of chaos
Eric Brunner, Lukas Pausch, Edoardo G. Carnio +3
We unveil the signature of many-body interference across dynamical regimes of the Bose-Hubbard model. Increasing the particles' indistinguishability enhances the temporal fluctuati…
How to seed ergodic dynamics of interacting bosons under conditions of many-body quantum chaos
Lukas Pausch, Edoardo G. Carnio, Andreas Buchleitner +1
We demonstrate how the initial state of ultracold atoms in an optical lattice controls the emergence of ergodic dynamics as the underlying spectral structure is tuned into the quan…
Propagation of two-particle correlations across the chaotic phase for interacting bosons
Ãscar Dueñas, David Peña, Alberto RodrÃguez
We analyze the propagation of experimentally relevant two-particle correlations for one-dimensional interacting bosons, and give evidence that many-body chaos induces the emergence…
