Greiner Lab
Welcome to the Greiner Lab!
We use ultracold quantum gases on optical lattices to simulate models from condensed matter physics. Thanks to the microscopy technique developed here, we can see and manipulate individual atoms to perform experiments with remarkable levels of control and accuracy.
For the nonexperts, the 10-minute documentary introducing the background, motivation, and apparatus of our lab is a great starting point. To learn about the sciences, follow the links in the navigation bar to each individual lab.

Adiabatic State Preparation in a Quantum Ising Spin Chain
04/2024
arXiv:2404.07481
We report on adiabatic state preparation in the one-dimensional quantum Ising model using ultracold bosons in a tilted optical lattice. We prepare many-body ground states of controllable system sizes and observe enhanced fluctuations around the transition between paramagnetic and antiferromagnetic states, marking the precursor of quantum critical behavior. Furthermore, we find evidence for superpositions of domain walls and study their effect on the many-body ground state by measuring the populations of each spin configuration across the transition. These results shed new light on the effect of boundary conditions in finite-size quantum systems.
