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…
