Listening to the sound of dark matter with superfluid helium
Abstract: Superfluid helium-4 at millikelvin temperatures is an ideal ac
Diffraction minima resolve point scatterers at tiny fractions (1/80) of the wavelength
Abstract: From bio-physics to quantum simulators, many fields depend on sub-diffraction imaging of multiple point sources.
Leveraging the flexibility of automatic differentiation-based modeling in reflection ptychography
Abstract: ‘Experiments whose data are processed using a computational model are often plagued by unc
Demonstrating beam splitters for reaction pathways in the field of cold chemistry
Our group studies chemical reactions of ultracold Rb atoms in a state-to-state
resolved fashion, where we prepare reactants in well defined quantum states and
measure the quantum states of the molecular products. In particular, we focus on
three-body recombination where three atoms collide, forming a diatomic molecule.
The third atom carries away part of the binding energy. We are currently
investigating methods to gain control over this chemical reaction. By making use of
Open dynamics with non-Gaussian states, and a Long-range Rydberg-ion molecule in a Paul trap
Abstract: In this talk, I’ll discuss a new framework to simulate the open dynamics of many-boson quantum systems. We use a superposition of squeezed-displaced states as a non-Gaussian state (NGS) ansatz. It is not restricted to a low excitation subspace, and can describe a variety of interesting quantum states (eg. squeezed cat states).
