| An ultracold pizza of dipolar molecules |
| Speaker: | Matteo Ciardi (TU Wien) |
| Abstract: | Dipolar molecules are emerging as a viable ultracold platform with strong interactions, opening new possibilities for quantum metrology, computing and simulations. In our numerical simulations, performed with the Path Integral Monte Carlo (PIMC) method, we predict that exotic ultracold phases should form with realistic experimental parameters: from anisotropic droplets to monolayer crystals.
This talk will introduce the physics of ultracold dipolar molecules and their relevance to quantum many-body physics, especially for the quantum simulation of strongly correlated phases of matter. We will also discuss the basics of the PIMC simulation method, and its relevance to the description and understanding of these fascinating physical systems.

| MBI colloquium: Exploring the Uncharted Waters of Wavelike Dark Matter |
| Speaker: | Saarik Kalia (IFAE Barcelona) |
| Abstract: | Dark matter in the ultralight regime behaves like classical waves rather than particles, so unique detection strategies are needed. In this talk, we will focus on the extremely low-mass regime, which experiments have yet to explore. We will utilize precision magnetic-field measurements to navigate this parameter space. I will show how geomagnetic field data from the SuperMAG collaboration have set the first direct constraints in this regime, and I will describe ongoing efforts by the SNIPE Hunt collaboration to collect more data. I will also demonstrate that state-of-the-art magnetically levitated (Maglev) systems can act as strong probes for several models of ultralight dark matter. Finally, I will discuss recent work motivating regions of self-interacting scalar dark matter parameter space. |

| Particle motion in superposed gravitational fields |
| Speaker: | Marko Vojinovic (Institute of Physics University of Belgrade) |
| Abstract: | We will discuss the effective equation of motion for a small body, approximated
as a point particle, moving in a superposition of two distinct gravitational
field configurations, within the framework of an abstract model of quantum
gravity. Given some minimal general assumptions about the quantum gravity model,
and under a certain approximation scheme, one can derive an effective equation
of motion of the particle, which contains correction terms to the standard
geodesic equation. We will discuss the origin and nature of these correction
terms, especially their dependence on the interference terms between two
quantum states of the gravitational field. If time permits, we will also
comment on the implications for the weak equivalence principle. |
