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…

Learning Minimal Representations of Many-Body Physics from Snapshots of a Quantum Simulator
Frederik Møller, Gabriel Fernández-Fernández, Thomas Schweigler +3
Analog quantum simulators provide access to many-body dynamics beyond the reach of classical computation. However, extracting physical insights from experimental data is often hind…
