BAföG-Demo in Bonn

BAföG für Alle! Demo in Bonn am Di., 6.8.2024. Gemeinsame Abfahrtt von Köln Süd: 12:50 Uhr Gleis 1. Start der Demo auf dem Bonner Marktplatz: 14:00 Uhr

Dienstag, 6.8.
– 12:50 Uhr: Gemeinsame Anfahrt von Köln Süd, Gleis 1
– 14:00 Uhr: Start der Demo auf dem Bonner Marktplatz

In ihrem Koalitionsvertrag hatte die Ampel-Koalition angesichts zu kleiner, aber kontinuierlicher Proteste, an denen wir uns auch immer beteiligt haben, eine grundsätzliche BAföG-Reform angekündigt. Diese Reform würde angesichts der „Zeitenwende“ fast komplett gestrichen. Die zum nächsten Semester beschlossenen Änderungen sind noch nicht einmal ein Ausgleich der zwischenzeitlichen Inflation und der Höchstsatz reicht nach wie vor nicht zum Überleben und ein Drittel aller Studierenden ist armutsgefährdet. Die 1971 mit dem Bafög erkämpfte Garantie des Rechts auf Bildung für Alle verkommt zur Farce.

Es ist Zeit für einen Paradigmenwechsel: Statt „Zeitenwende“ brauchen wir eine Studienfinanzierung, die den Dauerzustand der Prekarität aufhebt und das Menschenrecht auf Bildung für alle ermöglicht! Wir brauchen eine Studienfinanzierung, die unabhängig von Elternhaus und Staatsbürgerschaft allen ein unbedrängtes und kritisches Studium ermöglicht.

Deshalb schließen uns der Bonner Demo an, die von einigen Bonner Hochschulgruppen, einigen Bonner Fachschaften, dem wissenschaftlichen Personalrat der Uni Bonn und dem Bonner SDAJ getragen wird.

Bibliotheksumfrage // Library Survey

Die Prüfungsphase steht an und die Arbeitsplätze in der Physik-Bibliothek sind sehr gut belegt – durch Physik-Studierende, aber inzwischen zunehmend auch durch Studierende anderer Fächer.

Anhand einer kleinen Umfrage möchte Ute Graffenberger, unserer Bibliothekarin, herausfinden, wer aus welchen Gründen in die Bibliothek kommt, aber auch, wer warum vielleicht nicht kommt.

Die Umfrageergebnisse sollen bestenfalls dazu führen, dass einige Bibliotheksservices neu angeboten oder verbessert werden – nicht nur in der Physik, sondern vielleicht an der ganzen Uni.

Die Umfrage dauert nur wenige Minuten und hat bewusst viele freie Kommentarfelder. Ihr könnt im Eingangsbereich sbib/CIP die Papierversion ausfüllen oder auch online.

 The examination phase is approaching and the the physics library is very busy – with physics students, but now increasingly also with students from other subjects.

Ute Graffenberger, our librarian, would like to use a small survey to find out who comes to the library and why, but also who perhaps doesn’t come and why.

At best, the results of the survey should lead to some library services being offered or improved – not only in Physics, but perhaps at the whole university.

The survey only takes a few minutes and deliberately has many free comment fields. You can fill in the paper version in the sbib/CIP entrance area or online.

Student council shows solidarity with striking Nature workers

Natur workers on strikeNature, one of the most prestigious journals, thrives on letting university employees around the world work for it free of charge. As part of the conversion of the publication system to open access, which we very much welcome, there is an attempt to rip off the universities even more.

At the same time, Nature does not consider it necessary to pay its own employees appropriately. After months of negotiations, they are now on strike. We show solidarity with the colleagues at Nature:

„We, as a physics student council, stand in solidarity with the workers! It can only be in anyone’s interest that publicly funded research is openly accessible. Due to an overly competitive scientific system, many people rely on publishing in prestigious journals, such as Nature, to pursue their careers or apply for grants. In this position of power, nature openly abuses by charging enormously high amounts of money for publishing open access. Many institutions struggle to afford it or are even ruled out directly. Nevertheless, these large profit margins are by no means represented in the workers‘ salaries! We fully support the demands of the strike.“

GPK: Unconventional magnetism in spintronics: the emergence of altermagnetism and beyond


Tuesday, 4th of June, 16.00
(16.00 Coffee & Cake in the foyer, 16.30 talk & discussion)
Lecture Hall III

Antiferromagnetic spintronics has been a very active research area of condensed matter in recent years. Magnetic order was then also discovered in momentum space, which in turn led to the discovery of completely new magnetic phases beyound ferromegnetism and anti-ferromegnetism: Atermagnets.

Jairo Sinova from Univerity Mainz will cover in his talk the basic introductory view to altermagnetism and its consequences to spintronics as well as new emerging exchange driven phenomena akin to spin-orbit coupling effects, such as p-wave magnetism, emerging from the basic concepts that gave rise to the discovery of altermagnetism.

Building quantum space-time with spin foams

Informal Discussion with interested students
Thursday, July 11, 11:00
KOSMA-Room (meeting in foyer)

Talk in Theory Colloquium
Friday, July 12, 16:30
Seminar room ETP

 

Spin foam quantum gravity is a non-perturbative, background independent approach to quantizing gravity. It formulates a path integral as a sum over quantum geometries encoded in group theoretic data as in loop quantum gravity; thus it is frequently seen as a way of defining a covariant dynamics for this theory. In this talk, Sebastian Steinhaus from Jena wants to motivate quantum gravity as a manifestly background independent theory and define the gravitational path integral à la spin foams. As a regularisation, he introduces a triangulation and discuss how gravity can be formulated in the discrete, via Regge calculus in a piece-wise flat way. Then he discusses how quantum geometry is encoded in a spin foam and how it connects to Regge calculus in a putative semi-classical limit. He will review outstanding research challenges, in particular for the Lorentzian theory, and discuss concretely the construction of a cosmological model coupled to a scalar field.

GPK: Hot QCD matter flowing as a fluid


Tuesday, 4th of June, 16.00
(16.00 Coffee & Cake in the foyer, 16.30 talk & discussion)
Lecture Hall III

Very high energy densities are reached in ultra-relativistic collisions of heavy ions. Under these conditions, the confinement in strongly-interacting matter is lifted, and a quark-gluon plasma (QGP) is formed. At the highest temperatures realized in the laboratory, this system offers us the opportunity to study QCD matter under extreme conditions.

The successful heavy-ion program at the LHC provides data of increasing precision. Silvia Masciocchi (Universität Heidelberg und GSI Darmstadt) will illustrate how experimental evidence supports the description of the QGP by fluid dynamics. This description together with neural networks and Bayesian inference allow to determine fundamental properties of QCD with increasing precision.
