Special Seminar: Prof. Shigemasa Suga - Photoelectron Momentum Microscopy and Soft X-ray Resonant Inelastic Scattering with spatial resolution down to sub-μm scale and prospect of their operand measurements

Osaka University High resolution spin- and angle-resolved photoelectron spectroscopy (SP-ARPES) in micro-nano regions is very widely demanded in order to clarify surface and bulk electronic structures of solids by tuning the excitation photon energies (hν). Spatial resolution is also beneficial for development of spintronics devices. However, extremely low spin detection efficiency has hindered its progress over decades until very recently. The development of a momentum microscope (M.M.) composed of a PEEM type input lens and an aberration corrected tandem S-type double hemispherical deflection analyzers (DHDAs) has opened a breakthrough. 2 dimentional (2D) momentum dependent E B (k x ,k y ) can be measured in a very wide k space with high energy and momentum resolutions better than 12 meV and 0.005 Å -1 . Nearly 10,000 (k x ,k y ) points can be simultaneously measured over a full surface/ bulk Brillouin zone (BZ) at the same time for a certain E K (or E B ). 2D imaging spin filter such as Au/Ir(001) can be installed behind this M.M. Then spin asymmetric 2D E B (k x ,k y ) images can be recorded at two electron incidence energies (10.25 & 11.5 eV) with opposite sign of spin sensitivity. From these two spectra, spin resolved spectrum in the wide k space is easily derived in the form of P s (E B (k x ,k y )). P s (E B (k x ,k y ,k z ) detection is very easy by changing hν. Since the PEEM can collect whole 2π steradian emitted photoelectrons, 2D multi-channel figure of merit of this spin detection is more than ∼million times or sometimes sub-billion times higher than the Mott detector and spin-LEED detector and even ∼10,000 times higher than the most advanced Fe-O VLEED spin detector. Examples of SP-ARPES measurements of surface Rashba states as well as Dirac cone states of topological insulators by 2D spin filter will be presented. Photoelectron spectroscopy is only useful to conductive materials. In the case of insulating materials, the charging up effects spoils the ARPES, though the details knowledge of their electronic structures are as well demanded quite often. In such a case, photon-in and photon-out experiment as RIXS is ideal, although the micronano study requires the focusing of the excitation synchrotron radiation. The advantage of RIXS is the possibility to be measured under any external perturbations. I will show an example of a study of half metal Heusler alloy under an external magnetic field. Abstract

Special Seminar: Walid G. Malaeb - Photoemission spectroscopy studies on high-Tc superconductors and topological materials

Department of Natural Sciences, Lebanese American University Photoemission Spectroscopy (PES) is a powerful technique in directly probing the electronic structure of solids especially in its angle-resolved mode (ARPES). For this purpose, synchrotron radiation as well as high-resolution lasers and other light sources have been used. In this talk, I will present how we have been implementing this technique to uncover various aspects of the electronic structure of quantum materials, in particular the iron-pnictide high-Tc superconductors from the early stage since their discovery in Japan in 2008. The discussion will include the core energy levels, the three-dimensional electronic structure, the Fermi surfaces and superconducting gaps, the coupling to bosonic modes, etc. I will also present our recent work on alpha-Sn which has recently gained much attention due to the diverse tunable topological phases it can reveal ranging from a topological insulator (TI) to a topological Dirac semimetal (TDS) depending on the applied strain in addition to its simple elemental structure, non-toxic nature and great potential for applications. Finally, I will make a brief overview on the recent research projects we have launched at LAU. Abstract

As astrophysics continues to try to become more diverse and more inclusive, the interviews with intersectional astrophysicists provide insights into supportive and unsupportive factors related to their retention. This presentation will contain film clips from the interviews to illustrate points.

Traditionally, the Department of Physics opens its doors to everyone interested in physics and science in general for the Long Night of Science. Our guests experience a variety of exciting lectures, laboratory tours and experiments. Various experiments invite young and old to try them out and marvel. Program 2022

Research Group Pitches – Physicists present their scientific work and teams

On-site Event at the Physics Department Different research groups will present their research and teams in short 5-minute talks. Within two hours, students can gain a quick overview of the range of topics in our department and think about possible questions for bachelor's and master's theses.

Location: Study Center "BoB"

Physics Colloquium & TRR 227: Prof. Hermann Dürr - Ultrafast spin-lattice dynamics in magnetic materials

Pathways in Physics: Sebastian Beumler From mono-physicist to award-winning physics teacher

Sebastian Beumler studied physics at Humboldt University. After graduating, he benefited from a lateral entry program and started as a physics teacher at Beethoven-Gymnasium in Lankwitz. In 2015, Sebastian Beumler received a teacher’s award for his outstanding commitment to making physics lessons modern and inspiring – he was awarded the very first Heinrich Gustav Magnus Award of the Physical Society of Berlin. At "Pathways in Physics", Sebastian Beumler will talk about his entry into the teaching profession and his methods to open up the wonderful world of physics to pupils. Join

Pathways in Physics: Dr. Susanne Pudollek - Physicist for Safe Disposal of Nuclear Waste

Susanne Pudollek studied at our department and received her doctorate in the research group of Professor Dr. Robert Bittl. She then worked as a project manager for a Berlin-based engineering company (DSR Ingenieurgesellschaft mbH) specializing in project management and consulting for operation and dismantling of nuclear facilities. Since March 2019, Dr. Susanne Pudollek heads the section unit “inventory and logistics” at the Swiss National Cooperative for the Disposal of Radioactive Waste ( Nagra ). At "Pathways in Physics" Susanne Pudollek will talk about her professional path from research activities at Freie Universität into radiation protection for safe use and disposal of radioactive materials.
