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…
Information in quantum field theory simulators: Thin-film superfluid helium
Maciej T. Jarema, Cameron R. D. Bunney, Vitor S. Barroso +3
Understanding quantum correlations through information-theoretic measures is fundamental to developments in quantum field theory, quantum information, and quantum many-body physics…
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…
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…
