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…
Experimentally probing the Quantum Physics in the Inverted Harmonic Oscillator
Si-Cong Ji, Philipp Schüttelkopf, Nataliia Bazhan +6
When a quantum system passes through an unstable fixed point the local dynamics reduces to the inverted harmonic oscillator (IHO). It exponentially amplifies along one quadrature w…
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…
Measurement of total phase fluctuation in cold-atomic quantum simulators
Taufiq Murtadho, Federica Cataldini, Sebastian Erne +4
Studying the dynamics of quantum many-body systems is often constrained by the limitations in probing relevant observables, especially in continuous systems. A powerful method to g…
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…
Identifying diffusive length scales in one-dimensional Bose gases
Frederik Møller, Federica Cataldini, Jörg Schmiedmayer
In the hydrodynamics of integrable models, diffusion is a subleading correction to ballistic propagation. Here we quantify the diffusive contribution for one-dimensional Bose gases…
