Femtosecond science on-chip: Capturing light-induced anomalous Hall currents in graphene (Dr. James McIver, Max Planck Institute for the Structure and Dynamics of Matter)

Jun 15, 2021 from 04:15 PM

Many non-equilibrium phenomena have been discovered or predicted in quantum solids driven by femtosecond pulses of light. Examples include photo-induced superconductivity [1] and Floquet-engineered topological phases [2]. These effects are expected to lead to measurable changes in electrical transport. However, the timescales involved far exceed those accessible using conventional fast electronics. In this talk, I will present results on the transport properties of monolayer graphene illuminated by a femtosecond pulse of circularly polarized light [3]. This was achieved using an ultrafast device architecture based on laser-triggered photoconductive switches. We observed a light-induced Hall effect in the absence of an applied magnetic field. The dependence of the effect on a gate potential used to tune the Fermi level revealed multiple features that reflect a Floquet-engineered topological band structure, similar to the band structure originally proposed by Haldane [4]. This includes a ~60 meV wide conductance plateau centered at the Dirac point, where a gap of equal magnitude is predicted to open based on Floquet theory. We find that when the Fermi level lies within this plateau, the non-equilibrium anomalous Hall conductance saturates around ~1.8+/-0.4 e^2/h.

Plasma 2020 – The US National Academies Decadal Assessment of Plasma Physics: Overview and Future Research Opportunities (Prof. Dr. Mark J. Kushner, University of Michigan)

Jun 29, 2021 from 04:15 PM

Photo Mark J. KushnerThe Board on Physics and Astronomy of the United States (US) National Academies conducts every-10-year assessments of the major fields of physics. The purpose of the decadal assessments is to provide an overview of the progress made in the field over the past decade and to highlight research opportunities in the coming decade. The Plasma 2020 Decadal Assessment of plasma physics, Plasma Science: Enabling Technology, Sustainability, Security, and Exploration, was released in draft form in May 2020 and in final form in April 2021. The report broadly addresses the field of plasma physics, with chapters focused on foundational processes, laser-plasma interactions, high energy density systems, low temperature plasmas, magnetically confined fusion and space plasmas. The Plasma 2020 report, in addition to being a science document of interest to the international community, is also a policy document which responds to the charge of the sponsoring US federal agencies for recommendations on how plasma science should be configured and funded in the US. These agencies are the National Science Foundation, Department of Energy and Department of Defense. As a result, the F&R (findings and recommendations) of the report are US focused, while also hopefully being of interest to the international community by being adaptable to their particular administrative structures.

In this presentation, an overview of the Plasma 2020 Decadal Assessment will be provided. The Decadal Assessment process will be briefly described, followed by highlights of the accomplishments, science opportunities and F&R across the field. More emphasis and detail will be provided for findings for low temperature plasmas.
A (free) pdf copy of the Plasma 2020 Decadal Assessment can be downloaded here.

International Conference NIBS 2021: 4th Nanotechnology and Innovation in the Baltic Sea Region

Aug 04, 2021 to Aug 06, 2021

online

LogoThe NIBS 2021 conference is the fourth annual NIBS conference with the series starting in 2017. NIBS is organized by the Mads Clausen Institute at the University of Southern Denmark, the Kaunas University of Technology, Lithuania and the North German Initiative Nanotechnology Schleswig-Holstein e.V. (NINa SH eV) network, led by Kiel University, Germany. Read more

Attendees from industry, academia and municipalities are invited to enter in a dialogue about the potential for interdisciplinary applications and new products from nanotechnology.

NIBS offers:

  • state-of-the-art stimulating presentations
  • matchmaking events
  • a dialogue platform between experienced and young researchers from industry and academia
     

NIBS provides presentations from companies and research institutions on current trends in the field of nanotechnology. Companies have the opportunity to communicate their success stories and the newest developments in-house. Young scientists present their work and find entrepreneurial opportunities.

Why NIBS?

In contrast to national conferences, NIBS brings together researchers and business stakeholders from the Baltic Sea Region (BSR) as well as parties involved in the cooperation with the BSR partners to share latest achievements in research, innovative solutions and applications in the field of nanotechnology. NIBS focuses on the BSR, where the innovation potential from newest technologies is utmost high.
The NIBS conference offers an ideal opportunity to increase your visibility as a scientist, company or other stakeholder in the field of nanotechnology within the Baltic Sea region. You can benefit from an active regional nanotechnology network and get a perfect stage to initiate new projects or start-ups and find new partners and customers, respectively.

Topics

  • Nanotech for Life Science
  • Nano energy
  • Nanomaterials
  • Nanooptics
  • Nanoelectronics
  • Sensors
  • Sustainable Nanotechnology

10th International Workshop on Functional Nanocomposites

Sep 07, 2021 to Sep 10, 2021

Varese, Villa Cagnola, Italien

The workshop aims on polymer metal nanocomposites. These nanocomposites may consist of polymer/metal in the shape of nanoclusters/nanoparticles, nanotubes, nanofibers, and nanowires. The event aims to bring together physicists, chemists, and engineers from academics and industries to combine their knowledge of nanocomposites advanced preparation techniques, new material properties and industrial applications. In addition computer simulations and theoretical work are included.

The workshop will have a hybrid format, both online and in presence at Villa Cagnola, Varese, Italy. If the COVID restrictions are still in place, it will be held entirely online.

Organizing Committee

Paolo Milani, University of Milan, Milan, Italy, Workshop Chair  
Andrey Choukourov, Charles University, Prague, Czech Republic, Workshop Vice Chair  
Franz Faupel, Kiel University, Kiel, Germany     
Noemi De Lorenzo, University of Milan, Milan, Italy, Workshop Secretary
