Bi-directional universal dynamics in a spinor Bose gas close to a non-thermal fixed point

Christian-Marcel Schmied, Maximilian Prüfer, Markus K. Oberthaler +1

We numerically study the universal scaling dynamics of an isolated one-dimensional ferromagnetic spin-1 Bose gas. Preparing the system in a far-from-equilibrium initial state, simu…

Dating glacier ice of the last millennium by quantum technology

Zhongyi Feng, Pascal Bohleber, Sven Ebser +8

Radiometric dating with 39Ar covers a unique timespan and offers key advances in interpreting environmental archives of the last millennium. Although this tracer has been acknowled…

Emulating quantum computation with artificial neural networks

Christian Pehle, Karlheinz Meier, Markus Oberthaler +1

We demonstrate, that artificial neural networks (ANN) can be trained to emulate single or multiple basic quantum operations. In order to realize a quantum state, we implement a nov…

Velocity selected production of metastable positronium

C. Amsler, M. Antonello, A. Belov +52

Positronium in the metastable state exhibits a low electrical polarizability and a long lifetime (1140 ns) making it a promising candidate for interferometry experiments wit…

Ar dating with small samples resolves ocean ventilation

S. Ebser, A. Kersting, T. Stöven +6

Ocean ventilation is the integrated effect of various processes that propagate surface properties to the ocean interior. Its precise understanding is the prerequisite for addressin…

Quenches near criticality of the quantum Ising chain---power and limitations of the discrete truncated Wigner approximation

Stefanie Czischek, Martin Gärttner, Markus Oberthaler +2

The semi-classical discrete truncated Wigner approximation (dTWA) has recently been proposed as a simulation method for spin- systems. While it appears to provide a powerful a…
