DESCRIPTION:Johannes Deiglmayr\, Universität Leipzig\n \nElectronic states
of atoms and molecules with high values of the principal quantum number n a
re called Rydberg states. Their exaggerated properties\, such as electronic
radii exceeding tens of nanometers and very large electric dipole moments\
, have attracted the interest of researchers since their discovery more tha
n hundred years ago. The universal and simple electronic structure of Rydbe
rg atoms and molecules facilitates precision measurements for the determina
tion of fundamental constants\, the controlled study of quantum-mechanical
effects in chemical reactions\, the creation of exotic molecular species an
d phases of matter\, and many more applications in physics and chemistry.\n
\nIn this talk\, I will introduce these applications and then focus on our
current experimental studies on the formation of exotic molecular bonds\, u
sing laser-cooled atoms and ultra-stable laser sources from the mid-IR to t
he UV range. I’ll also give an outlook on future research directions.\n \nB
efore the lecture\, coffee and cookies are offered in front of the lecture
hall.\nAfter the lecture\, everyone is invited to a reception in the Aula.\
n\nWe kindly ask you to observe the currently applicable measures for infec
tion protection.

DESCRIPTION:Prof. Dr. Inti Sodemann Villadiego\, Universität Leipzig \n \nT
he Spinon Fermi Surface State is a fascinating quantum state of matter that
features particles with spin-charge fractionalization and emergent gauge f
ields. Its existence was conjectured by Phil Anderson in the 80’s\, but des
pite decades of research its detection in real materials has remained elusi
ve.\n\nI will describe new ideas on how to search for this state in experim
ents. I will show how in spite of being an electrical insulator\, this stat
e can display quantum oscillations and low frequency cyclotron resonances i
n response to magnetic fields. I will also describe how its peculiar magnet
ic noise could be detected with nitrogen vacancy center sensors.\n\nI will
also introduce a new “pseudo-scalar” variant of the original Anderson's Spi
non Fermi Surface State\, inspired by the recent experimental discovery of
oscillations of the thermal conductivity in the material α-RuCl3. This allo
ws to understand why α-RuCl3 can display quantum oscillations of the therma
l conductivity without an accompanying thermal Hall effect. \n\n \n

DESCRIPTION:Prof. Dr. Oskar Hallatschek\, Universität Leipzig\n \nMicrobes
often colonize spatially-constrained habitats\, such as pores in the skin o
r crypts in the colon. The resulting micro-communities can be very stable a
nd contribute to the long-term function of our microbiomes. Due to a lack o
f spatio-temporal observations\, it is however unclear how these communitie
s and their ecological functions arise. Using microfluidic devices to syste
matically vary ecological correlation lengths\, we uncover sharp transition
s between different colonization states with different evolutionary propert
ies. Our results show that density-dependent passive diffusion can drive re
producing populations to a jamming threshold\, which entails supreme resili
ence against invaders at the cost of a total loss of mixing and intra-speci
es competition. These results elucidate how cell proliferation can drive un
ique non-equilibrium phase transitions (different from MIPS). The emerging
sensitivity to scale\, foreshadowed in the field of island biogeography\, u
nderscores the need to control for scale in microbial eco-evolutionary expe
riments.
