Gerhard Ertl Lecture & Award

Gerhard Ertl Lecture & Award

The Ertl Lecture Award was established in 2008 by the three Berlin universities (Humboldt University, Technical University and Free University) and the Fritz Haber Institute of the Max Planck Society and is awarded once a year. It commemorates former FHI Director Gerhard Ertl's Nobel Prize in Chemistry, which he received in 2007. The prize honours outstanding personalities and researchers in the field of catalysis where Ertl carried out exceptional research for many decades. The prize, sponsored by BASF, includes a one-week research stay at the participating Berlin institutions and a keynote lecture. The winner is typically announced in Spring, the lecture takes place around the December 10th, the anniversary of Ertl's Nobel Prize reception.

The discovery and applications of topological quasiparticles by ultrafast microscopy

  • PC Department Online Seminar
  • Date: Oct 19, 2021
  • Time: 11:00 AM (Local Time Germany)
  • Speaker: Prof. Hrvoje Petek
  • University of Pittsburgh
  • Host: Martin Wolf
Surface plasmon polaritons (SPP) are composite electromagnetic field-charge density wave collective modes that propagate at metal/dielectric interfaces at the local speed of light. The circulation of their fields from transverse to longitudinal causes a transverse spin angular momentum (SAM) locking known as quantum spin-Hall effect, which embodies the property of evanescent waves, such as SPPs, that changing the sign of the photon momentum direction changes the sign of its spin. In other words, the oppositely propagating SPP waves possess the opposite spin. SPP fields can also carry optical angular momentum (OAM), which can focus them into plasmonic vortices. [more]

On-Surface Chemistry of Helicenes

  • Department Online Seminar
  • Date: May 2, 2022
  • Time: 11:00 AM (Local Time Germany)
  • Speaker: Karl Heinz Ernst
  • EMPA, Dübendorft, Switzerland
  • Host: Martin Wolf
Surfaces functionalized with helicenes are of interest for chiroptical electronic devices or for electron-spin filtering. While self-assembled layers facilitate studying interesting phenomena, covalently linked chiral modified materials would be much more robust and therefore better suited for applications. [more]

Water Flows in Carbon Nanochannels, from Carbon Memories to Quantum Friction

The emerging field of nanofluidics explores the molecular mechanics of fluids. This world of infinitesimal fluidics is the frontier where the continuum of fluid dynamics meets the atomic nature of matter, or even its quantum nature. Nature fully exploits the fluidic oddities at the nanoscale and it is capable of breath-taking technological feats using a fluidic circuitry made of multiple biological channels, such as ionic pumps, proton engines, ultra-selective pores, stimulable channels, ...

Chemical dynamics at extended scales

Chemical dynamics at extended scales
  • Start: Jan 10, 2023 09:00 AM (Local Time Germany)
  • End: Jan 11, 2023 06:00 PM
  • Location: Harnack House
  • Host: Martin Wolf
The Fritz Haber Institute of the Max Planck Society, in short FHI, is an international research place where scientists from all over the world investigate the basic principles underlying the chemical conversion of matter and energy at surfaces and interfaces. Our institute was celebrating the 110th anniversary of its inauguration this October and we are also approaching a generation change with the upcoming retirements of three directors (Schlögl, Wolf, and Meijer) in the coming years. This is an excellent moment to further develop the institute’s strategy and research concept, and to identify the upcoming fields for the next decades in physical chemistry and chemical physics in Berlin-Dahlem.

Theory of Higgs Spectroscopy: How to Activate and Detect the Higgs Mode

  • PC Department Seminar
  • Date: Sep 27, 2023
  • Time: 11:00 AM (Local Time Germany)
  • Speaker: Dirk Manske
  • Max Planck Institute for Solid State Research, Stuttgart
  • Location: Building G
  • Room: 2.06
  • Host: Martin Wolf
Higgs spectroscopy is a new and emergent field that allows to classify and determine the superconducting order parameter by means of ultra-fast optical spectroscopy. There are two established ways to activate the Higgs mode in superconductors, namely a single-cycle ‘quench’ or an adiabatic, multicycle ‘drive’ pulse. [more]

Single-molecule imaging and engineering of biological and synthetic molecular motors

  • PC Department Seminar
  • Date: Nov 30, 2023
  • Time: 11:00 AM (Local Time Germany)
  • Speaker: Ryota Iino
  • Institute for Molecular Science, National Institutes of Natural Sciences, Japan
  • Location: Building G
  • Room: 2.06
  • Host: Martin Wolf
Molecular motors, an important class of molecular machines, harness various energy sources to move unidirectionally [1]. The operational principles of molecular motors are distinct from those of man-made macroscopic motors, because they have nanoscale dimensions and generally work in a solution environment where viscosity is dominant. Under these low Reynolds number, overdamped conditions, they cannot rely on inertia to sustain motion. Furthermore, they are continually agitated by random Brownian motion, which provides both challenges and opportunities for the unidirectional motion. [more]
