„Inelastic collapse of perfectly inelastic particles“

The FAU has published a press release about one of our most recent papers.

Our recent paper „Systematic Onset of Periodic Patterns in Random Disk Packings” by Nikola Topic, Thorsten Pöschel and Jason Gallas in Physical Reciew Letters 120, 148002 (2018) was featured on the website of the Brazilian Physical Society.

Automatisch periodisch: Zufällige Packungen gleich großer Scheiben zwischen parallelen Wänden bilden stets eine perio­dische Struktur.

Physiker der Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) haben nachgewiesen, dass zufällige Packungen gleich großer Scheiben zwischen parallelen Wänden immer eine periodische Struktur bilden – unabhängig von der Breite des Behälters.

Physiker der Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) und der Heinrich-Heine-Universität Düsseldorf (HHU) haben nachgewiesen, dass sich Systeme entgegengesetzt rotierender makroskopischer Teilchen entmischen und homogene Fraktionen aus entweder rechts- oder links­drehenden Partikeln bilden.

Am 9. März 2018 endete die 31. Parabelflug­kampagne des Deutschen Zentrums für Luft- und Raum­fahrt (DLR) erfolgreich: Zwölf Experimente aus Human­physiologie, Biologie, Physik, Technologie­erprobung und Material­wissenschaften befanden sich an Bord des A310 Zero-G.

Science News channel “IQ-Wissenschaft und Forschung” of Bayerischer Rundfunk (BR2) reports on our recent results on the velocity distribution of active granular particles.

Die kinetische Energie von Teilchen in granularen Gasen, etwa Staub­wolken, kann temporär steigen, obwohl dem System stetig Energie ent­zogen wird. Das konnte jetzt ein inter­natio­nales Forscher­team erst­mals zeigen.

A team of five MSS researchers works currently in Bordeaux to perform parabolic flights. Focus of the experiments are the dissipative properties of granular systems under conditions of microgravity. Further, they perform an educational experiment regaring gyroscopic stabilisation of objects in weightlessness.

Prof. Brilliantov (University Leicester, UK) is one of the most recognized scientists in the field of Kinetic Theory and Statistical Mechanics of granular matter. He will visit MSS for one month to collaborate on phase transitions of systems of active granular particles.

Moderne Verfahren, wie Computertomographie und numerische Simulationen, führen dazu, dass immer mehr Forschungsergebnisse aus dreidimensionalen Datensätzen bestehen. Der Lehrstuhl MSS zeigt in Zusammenarbeit mit der theoretischen Physik und der Nürnberger Firma Cykyria wie sich solche Datenmengen mit Hilfe von virtueller Realität anschaulich darstellen lassen.

This week the final experiments at the drop tower facility in Bremen were performed. We have now the first results of the drop tower experiment: Imbibition of a water drop into a porous medium in zero-gravity.

For details please see Drop Your Thesis 2015.

The recording from the presentation of Prof. Pöschel at the „Lange Nacht der Wissenschaften“ is now available online as a web stream:
Unbeschwert forschen – Experimentelle Wege zur Schwerelosigkeit (M4V, HD ready (1280x720p))
You can also find the stream in lower qualities or to download here: Unbeschwert forschen – Experimentelle Wege zur Schwerelosigkeit

There are some more impressions of the „Lange Nacht“ in Media Coverage.

Today three of our colleagues, Jonathan, Laura, and Flo, started for the drop tower facility in Bremen. There they will put the last pieces of the experiment together and perform the last mechanical and security tests. The actual drop of the experiment is scheduled for beginning of next week. We wish them good luck and good data.
