Dispersive Shock Waves in a 1D Quantum Liquid
Philipp Schüttelkopf, Mohammadamin Tajik, Federica Cataldini +8
We implement a moving boundary condition in a 1D quantum liquid to study nonlinear wave breaking and its regularization by dispersion. Programmable optical potentials allow us to c…
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…
Characterising transport in a quantum gas by measuring Drude weights
Philipp Schüttelkopf, Mohammadamin Tajik, Nataliia Bazhan +4
Transport properties play a crucial role in defining materials as insulators, metals, or superconductors. A fundamental parameter in this regard is the Drude weight, which quantify…
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…
