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…
The role of non-Markovian dissipation in quantum phase transitions: tricriticality, spin squeezing, and directional symmetry breaking
Baptiste Debecker, Lukas Pausch, Jonathan Louvet +3
Understanding how to control phase transitions in quantum systems is at the forefront of research for the development of new quantum materials and technologies. Here, we study how…
Dissipative phase transition: from qubits to qudits
Lukas Pausch, François Damanet, Thierry Bastin +1
We investigate the fate of dissipative phase transitions in quantum many-body systems when the individual constituents are qudits (-level systems) instead of qubits. As an examp…
