Damping of phonons in one-dimensional quantum fluids
Federica Cataldini, Nataliia Bazhan, João Sabino +7
Collective excitations in one-dimensional (1D) quantum fluids are expected to propagate almost without dissipation. Here we directly excite phonon modes in a weakly interacting 1D…
Experimentally probing Landauer's principle in the quantum many-body regime
Stefan Aimet, Mohammadamin Tajik, Gabrielle Tournaire +6
Landauer's principle bridges information theory and thermodynamics by linking the entropy change of a system during a process to the average energy dissipated to its environment. A…
Experimental Observation of Curved Light-Cones in a Quantum Field Simulator
Mohammadamin Tajik, Marek Gluza, Nicolas Sebe +10
We investigate signal propagation in a quantum field simulator of the Klein-Gordon model realized by two strongly coupled parallel one-dimensional quasi-condensates. By measuring l…
Experimental verification of the area law of mutual information in a quantum field simulator
Mohammadamin Tajik, Ivan Kukuljan, Spyros Sotiriadis +10
Theoretical understanding of the scaling of entropies and the mutual information has led to significant advances in the research of correlated states of matter, quantum field theor…
Floquet engineering a bosonic Josephson junction
Si-Cong Ji, Thomas Schweigler, Mohammadamin Tajik +5
We study Floquet engineering of the tunnel coupling between a pair of one-dimensional bosonic quasi-condensates in a tilted double-well potential. By modulating the energy differen…
Emergent Pauli blocking in a weakly interacting Bose gas
Federica Cataldini, Frederik Møller, Mohammadamin Tajik +6
The relationship between many-body interactions and dimensionality is integral to numerous emergent quantum phenomena. A striking example is the Bose gas, which upon confinement to…
Mechanisms for the emergence of Gaussian correlations
Marek Gluza, Thomas Schweigler, Mohammadamin Tajik +8
We comprehensively investigate two distinct mechanisms leading to memory loss of non-Gaussian correlations after switching off the interactions in an isolated quantum system underg…
Thermometry of one-dimensional Bose gases with neural networks
Frederik Møller, Thomas Schweigler, Mohammadamin Tajik +4
We design a neural network to extract and process features from absorption images taken of one-dimensional Bose gases in the quasi-condensate regime. Specifically, the network is t…
Quantum field thermal machines
M. Gluza, J. Sabino, N. H. Y. Ng +7
Recent years have enjoyed an overwhelming interest in quantum thermodynamics, a field of research aimed at understanding thermodynamic tasks performed in the quantum regime. Furthe…
Decay and recurrence of non-Gaussian correlations in a quantum many-body system
Thomas Schweigler, Marek Gluza, Mohammadamin Tajik +8
Gaussian models provide an excellent effective description of many quantum many-body systems ranging from condensed matter systems all the way to neutron stars. Gaussian states are…
Designing Arbitrary One-dimensional Potentials on an Atom Chip
Mohammadamin Tajik, Bernhard Rauer, Thomas Schweigler +6
We use laser light shaped by a digital micro-mirror device to realize arbitrary optical dipole potentials for one-dimensional (1D) degenerate Bose gases of 87Rb trapped on an atom…
