Observing the two-dimensional Bose glass in an optical quasicrystal
Jr-Chiun Yu, Shaurya Bhave, Lee Reeve +2
The combined effect of disorder and interactions is central to the richness of condensed matter physics and can lead to novel quantum states such as the Bose glass phase in disorde…
Realizing discontinuous quantum phase transitions in a strongly-correlated driven optical lattice
Bo Song, Shovan Dutta, Shaurya Bhave +4
Discontinuous quantum phase transitions and the associated metastability play central roles in diverse areas of physics ranging from ferromagnetism to false vacuum decay in the ear…
AtomECS: Simulate laser cooling and magneto-optical traps
X. Chen, M. Zeuner, U. Schneider +3
AtomECS is a software package that efficiently simulates the motion of neutral atoms experiencing forces exerted by laser radiation, such as in magneto-optical traps and Zeeman slo…
Parametric instabilities of interacting bosons in periodically-driven 1D optical lattices
K. Wintersperger, M. Bukov, J. Näger +6
Periodically-driven quantum systems are currently explored in view of realizing novel many-body phases of matter. This approach is particularly promising in gases of ultracold atom…
Matter-wave diffraction from a quasicrystalline optical lattice
Konrad Viebahn, Matteo Sbroscia, Edward Carter +2
Quasicrystals are long-range ordered and yet non-periodic. This interplay results in a wealth of intriguing physical phenomena, such as the inheritance of topological properties fr…
Non-Equilibrium Mass Transport in the 1D Fermi-Hubbard Model
S. Scherg, T. Kohlert, J. Herbrych +6
We experimentally and numerically investigate the sudden expansion of fermions in a homogeneous one-dimensional optical lattice. For initial states with an appreciable amount of do…
