Ultrafast Phenomena at Surfaces
Our Main Research Topic
research program is devoted to the investigation of ultrafast phenomena
in solids, thin films and nanoparticles. This includes the combination
of short pulsed laser systems with surface science technology in order
to develop novel methods for measuring ultrafast relaxation processes
in real time with high temporal resolution.
The research activities are concentrated in the following areas:
February 2013—New Journal of Physics Highlights of 2012 A recent work on optimal open-loop near-field control of plasmonic nanostructures has been selected for inclusion in the 'Highlight of 2012' collection of the New Journal of Physics. The work results from a cooperation of the Bauer-group with the groups of Walter Pfeiffer (University of Bielefeld), Martin Aeschlimann (TU Kaiserslautern) and Tobias Brixner (University of Würzburg).

February 2013—PEEM study on plasmon pulse propagation published in Nano Letters In
a time-resolved PEEM experiment we studied the propagation of surface plasmon polariton wave packets in plasmonic focusing devices. The study is result of a
collaboration with the groups of Martin Aeschlimann (TU Kaiserslautern) and Carsten Reinhardt (Laser Zentrum Hannover). [link]
September 2012—study on time-domain classification of insulators published in Nature Communications In a time-resolved ARPES experiment different types of insulators were classified via time-domain discrimination. The results of a collaboration with the Rossnagel/Kipp group (Kiel) and the Murnane/Kapteyn group (Boulder, Colorado) are now online. [link]
June 2012—Gerald Rohde awarded for his diploma At
the graduation ceremony of the physics departement in Kiel, Gerald Rohde, member of the Bauer group, was awarded with a 'best diploma'
February 2012—Best Poster Prize for Ankatrin Stange At
the Gordon Research Conference “Ultrafast Phenomena in Cooperative
Systems” in Galveston, Texas, Ankatrin Stange was awarded with one of the
young investigator talks for her poster on time-resolved photoemission
studies of graphite. The presented work results from a close
cooperation of the AG Rossnagel/Kipp and the AG Bauer (University of Kiel).
September 2011—biannual seminar on solid state physics Five research groups from the IEAP in Kiel met from Sept. 28 to Sept 30 for the 11th biannual seminar on solid state physics in Sehlendorf/Kiel. Special guests of the meeting were Prof. K. Al-Shamery and Prof. C. Lienau from the University of Oldenburg. Thanks go to VG Scienta, SFB 677 and SFB 855 for support of the workshop!
July 2011—Poster Prize for Gerald Rohde At the summer school 'Exciting Excitations: From Methods to Understanding' organized by the SFB 616 at the University of Essen/Duisburg, Gerald Rohde was awarded a best poster prize. The presented results on the ultrafast dynamics in graphite and graphene were obtained in a collaboration with the AG Kipp/Rossnagel.
May 2011—Ankatrin Stange awarded for her diploma At the graduation ceremony of the physics departement in Kiel, Ankatrin Stange, member of the Bauer group, was awarded with a 'best diploma' award. Congratulations!
March 2011—study on laser induced CDW melting published in Nature In a cooperation with the Rossnagel/Kipp group we used ultrashort XUV light pulses in a time- and angle-resolved photoemission experiment to study the vaporizaton of a charge densiy wave in TiSe2. [link]
October 2010—work on FEL-based time-resolved photoemission experiment published in Phys. Rev. Lett. Femtosecond time-resolved core-level photoemission spectroscopy with the
free-electron laser FLASH was used to study the dynamics of a laser-induced melting of charge-order in TaS2. [link]
September 2010—DFG SPP 1391: PhD student seminar in Sehlendorf/Kiel More than 30 PhD students, diploma students and postdocs were invited to discuss projects and ongoing research within the DFG priority program “Ultrafast nanooptics.” For detailed information see Sektion Physik and Ultrafast nanooptics.
June 2010—BMBF project approved The project on ultrafast dynamics in strongly correlated and functional materials by Kai Rossnagel, Michael Bauer and Lutz Kipp will be granted for the next three years. The project is part of a cooperation with the University of Hamburg and aims for the development of a highly efficient time- and angle resolved solid state photoemission setup to be used at the free electron laser facility FLASH. [link] March 2010—Work on spatiotemporal control of nanooptical excitations published in PNAS In this cooperative work by the AG Pfeiffer (Universiy of Bielefeld), AG Brixner (University of Würzburg), AG Bauer (University of Kiel) and AG Aeschlimann (University of Kaiserslautern) we demonstrate that femtosecond pulse-shaping techniques can be utilized to switch highly localized light fields on ultrafast (femtosecond) time-scale.

March 2010—Best Poster Prize for Timm Rohwer At the Gordon Research Conference “Ultrafast Phenomena in Cooperative Systems” in Galveston, Texas, Timm Rohwer was awarded with one of the young investigator talks for his poster on time-resolved photoemission studies of TiSe2. The presented work results from a close cooperation of the AG Kipp and AG Bauer (University of Kiel) supported by Stefan Mathias (JILA/University of Colorado).
Feb. 2010—Most recent work on quantum-well-induced giant spin-orbit splitting in Bi/Cu(111) published in Phys. Rev. Lett. We report in this work on the observation of a Giant Rashba splitting of quantum well states in ultrathin Bi films. The paper results from a cooperation of groups from Kaiserslautern, Boulder, Kiel, Jülich, San Sebastian, and Tomsk. [link]
