In the workshop and seminar to be held at MPIPKS 10.07-04.08, 2017 eminent scientists in both fields will have an opportunity to engage in dialogues, to benefit from cross-fertilization, and to initiate new interdisciplinary collaborations.
Fluctuations have long been a focus of statistical mechanics, while climate and weather fluctuations are an essential part of the climate system. This seminar brings together researchers from the statistical mechanics and climate science communities to explore connections between the two fields and develop new multidisciplinary research directions.
Global warming is undeniably here and, for the welfare of the planet in the coming decades, it is urgent that we better understand changes to the climate. Since climate is the result of complex interactions between the atmosphere, oceans, polar ice, and life, it is a serious challenge to predict future conditions, especially extremes in the variability or fluctuations of climate.
A fundamental difficulty is that the solar radiation drives the climate system far away from thermal equilibrium, into a regime where the well established principles of thermodynamics developed in the 19th century cannot be reliably applied.
Non-equilibrium statistical mechanics is a rather young branch of theoretical physics that aims to identify overarching principles governing the behavior of such strongly driven systems, an endeavor that has been remarkably successful in recent years.
So far there has been only limited interactions between researchers in climate science and non-equilibrium statistical mechanics, despite important implications of the work in each of the two fields for the other.
In the workshop and seminar to be held at MPIPKS 10.07-04.08, 2017 on “Climate Fluctuations and Non-equilibrium Statistical Mechanics: an interdisciplinary dialogue,” eminent scientists in both fields will have an opportunity to engage in dialogues, to benefit from cross-fertilization, and to initiate new interdisciplinary collaborations.
Over 50 participants from 11 countries are expected to attend. Invited speakers include key figures in both areas, e.g., Profs. Jarzynski (Maryland, USA), Rahmstorf (Potsdam, DE), Seifert (Stuttgart, DE), and Dr. Penland (NOAA, USA).
A public lecture, entitled “Neue Daten aus der Klimaforschung: Bekommen wir die Klimakrise noch in den Griff?” will be given by Prof. Rahmstorf on Tuesday 18.07 at 19:00. Everyone is encouraged to attend.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
