- Abstract: In the past two decades, the revolutionary technologies of creating cold and
ultracold molecules have provided cutting-edge experiments for studying the
fundamental phenomena of collision physics. To a large degree, the recent
explosion of interest in the molecular collisions has been sparked by dramatic
progress of experimental capabilities and theoretical methods, which permit
molecular collisions to be explored deep in the quantum mechanical limit.
Tremendous experimental advances in the field has already been achieved, and
the authors, from an experimental perspective, provide a review of these
studies for exploring the nature of molecular collisions occurring at
temperatures ranging from the Kelvin to the nanoKelvin regime, as well as for
applications of producing ultracold molecules.

Thin Films [62.997667081978825]
Casimir forces, related to London-van der Waals forces, arise if the spectrum of electromagnetic fluctuations is restricted by boundaries.
We experimentally investigate the influence of self-assembled molecular bio and organic thin films on the Casimir force between a plate and a sphere.
We find that molecular thin films, despite being a mere few nanometers thick, reduce the Casimir force by up to 14%.

Magnetic field effects (MFE) in certain chemical reactions have been well established in the last five decades.
We employ elaborate and realistic models of radical-pairs, considering its coupling to the local spin environment and the sensor.
For two model systems, we derive signals of MFE detectable even in the weak coupling regime between radical-pair and NV quantum sensor.

We demonstrate cooling of a three-dimensional gas of fermionic sodium-potassium molecules to well below the Fermi temperature using microwave shielding.
The molecules are protected from reaching short range with a repulsive barrier engineered by coupling rotational states with a blue-detuned circularly polarized microwave.
This large elastic-to-inelastic collision ratio allows us to cool the molecular gas down to 21 nanokelvin, corresponding to 0.36 times the Fermi temperature.
