Observing the two-dimensional Bose glass in an optical quasicrystal
2 March 2023
Our latest work on observing the two-dimensional Bose glass in our optical quasicrystal is now on the Arxiv: Arxiv:2303.00737 . We could not only observe the Bose glass and the phase transition between Bose glass and superfluid, but could furthermore experimentally establish the non-ergodic character of the Bose glass...
Hubbard Models for Quasicrystalline Potentials
13 October 2022
Our latest work on creating Hubbard Models for Quasicrystalline Potentials is now on the Arxiv (2210.05691). In it, we present a numerical method for constructing the Hubbard Hamiltonian of non-periodic potentials without making use of Bloch's theorem, and then apply it to the eightfold rotationally symmetric 2D optical...

Towards quantum simulation of false vacuum decay
20 January 2022
In our lastest work we have used a resonantly driven optical lattice to turn the Mott transition into a first-order (discontinuous) transition. We were able to directly observe the associated hysteresis and metastability, where the system remains stuck in its original phase (the false vacuum) even though the ground state...
