Optimal route to quantum chaos in the Bose-Hubbard model
Lukas Pausch, Andreas Buchleitner, Edoardo G. Carnio +1
The dependence of the chaotic phase of the Bose-Hubbard Hamiltonian on particle number , system size and particle density is investigated in terms of spectral and eigenstate…
Chaos in the Bose-Hubbard model and random two-body Hamiltonians
Lukas Pausch, Edoardo G. Carnio, Andreas Buchleitner +1
We investigate the chaotic phase of the Bose-Hubbard model [L. Pausch et al, Phys. Rev. Lett. 126, 150601 (2021)] in relation to the bosonic embedded random matrix ensemble, which…
Chaos and ergodicity across the energy spectrum of interacting bosons
Lukas Pausch, Edoardo G. Carnio, Alberto Rodríguez +1
We identify the chaotic phase of the Bose-Hubbard Hamiltonian by the energy-resolved correlation between spectral features and structural changes of the associated eigenstates as e…
Many-body Multifractality throughout Bosonic Superfluid and Mott Insulator Phases
Jakob Lindinger, Andreas Buchleitner, Alberto Rodríguez
We demonstrate many-body multifractality of the Bose-Hubbard Hamiltonian's ground state in Fock space, for arbitrary values of the interparticle interaction. Generalized fractal di…
Signatures of indistinguishability in bosonic many-body dynamics
Tobias Brünner, Gabriel Dufour, Alberto Rodríguez +1
The dynamics of bosons in generic multimode systems, such as Bose-Hubbard models, is not only determined by interactions among the particles, but also by their mutual indistinguish…
Matter-wave scattering from strongly interacting bosons in an optical lattice
Klaus Mayer, Alberto Rodriguez, Andreas Buchleitner
We study the scattering of a matter-wave from an interacting system of bosons in an optical lattice, focusing on the strong-interaction regime. Analytical expressions for the many-…
