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…
Observation of area laws in an interacting quantum field simulator
Maciej T. Jarema, Mohammadamin Tajik, Jörg Schmiedmayer +2
Information shared between parties quantifies their correlation. The encoding of correlations across space and time characterises the structure, history, and interactions of system…
Identification and optimal control strategies for the transversal splitting of ultra--cold Bose gases
Nikolaus Würkner, Yevhenii Kuriatnikov, Karthikeyan Kumaran +5
Splitting a Bose--Einstein condensate (BEC) is a key operation in fundamental physics experiments and emerging quantum technologies, where precise preparation of well--defined init…
Momentum-resolved two-dimensional spectroscopy as a probe of nonlinear quantum field dynamics
Duilio De Santis, Alex Gómez Salvador, Nataliia Bazhan +6
Emergent collective excitations constitute a hallmark of interacting quantum many-body systems, yet in solid-state platforms their study has been largely limited by the constraints…
Nondestructive optomechanical detection scheme for Bose-Einstein condensates
Cisco Gooding, Cameron R. D. Bunney, Samin Tajik +6
We present a two-tone heterodyne optical readout scheme to extract unequal-time density correlations along an arbitrary stationary interaction path from a pancake-shaped Bose-Einst…
Fast Coherent Splitting of Bose-Einstein Condensates
Yevhenii Kuriatnikov, Nikolaus Würkner, Karthikeyan Kumaran +6
Preparation of non-trivial quantum states without introducing unwanted excitations or decoherence remains a central challenge in utilizing ultracold atomic systems for quantum simu…
Universal non-thermal fixed point for quasi-1D Bose gases
Qi Liang, RuGway Wu, Pradyumna Paranjape +4
Spatio-temporal scaling dynamics connected to non-thermal fixed points has been suggested as a universal framework to describe the relaxation of isolated far-from-equilibrium syste…
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…
Systematic analysis of relative phase extraction in one-dimensional Bose gases interferometry
Taufiq Murtadho, Marek Gluza, Khatee Zathul Arifa +3
Spatially resolved relative phase measurement of two adjacent 1D Bose gases is enabled by matter-wave interference upon free expansion. However, longitudinal dynamics is typically…
Hamiltonian Learning in Quantum Field Theories
Robert Ott, Torsten V. Zache, Maximilian Prüfer +5
We discuss Hamiltonian learning in quantum field theories as a protocol for systematically extracting the operator content and coupling constants of effective field theory Hamilton…
