Abstract |
Quantum simulation has enabled engineering and probing quantum matter
in new parameter regimes and with compelling novel probes. Individual
snapshots can reveal the position and spin of each atom in the system
thereby providing access to complex correlations in materials that are
often crucial to understand their behaviour. In my talk, I will
discuss recent progress on quantum simulation with ultracold atoms and
molecules in optical lattices and tweezers. The physics of strongly
correlated electronic materials can e.g. be efficiently realized using
ultracold fermionic atoms. Tuneable lattice geometries allow one to
introduce programmable geometries and mixed dimensional situations in
which doping can be continuously tuned. I will show how pairing of
charge carriers and extended stripe-like structures emerge under such
conditions due to an interplay of mobile dopant, mixed dimensions, and
an antiferromagnetic background. Polar molecules provide an
alternative platform for realizing long-range interacting itinerant
systems but have for a long time been plagued by uncontrolled losses.
I will delineate how such losses can be overcome using microwave
radiation and give rise to novel field-linked scattering resonances
that allow assembling larger ultracold molecular complexes also
opening the route to p-wave superfluids. Finally, I will discuss how
merging the techniques of optical lattices and optical tweezers
provides for a powerful platform for quantum simulation and computing
that has enabled the continued operation of large arrays of atoms over
time. |
