Lund Attoscience Symposium 2021

Different times need equally different ways of communication. As students and postdocs at the Lund Attosecond Science Center we have realized how difficult the interaction between us researchers has been in the past year. Week-long online conferences turn out to be very demanding and virtual seminars are too short to start real discussions. Therefore, we would like to try a new format to share research results in specific areas of attosecond science, with a particular focus on very recent topics and questions.  Anyone interested in Attosecond science is welcome to join! 

The  Lund Attoscience Symposium 2021  will offer monthly  two-hour sessions  on Wednesdays from 16.00 to 18.00. Each session focuses on one aspect of attosecond science and consists of one keynote lecture in addition to three progress reports from early career researchers. In-between the talks we will have time for discussions during casual coffee breaks. With this symposium we want to offer a platform to share the latest advances (and problems) as we would discuss them in an informal atmosphere during a regular conference.

How to attend the symposium

The meeting will mainly take place using This software enables lively discussions similar to what you would experience in a physical meeting, one of the aims of this symposium. To participate in the meeting, follow the link below. But remember: This will be similar to a regular conference. Come early to discuss with colleagues and find a seat well before the start of the presentation. 

Gather: (Google Chrome preferred) 

For better accessibility, the keynote presentation will be given in a Zoom webinar at 16:00. This can be accessed through Gather by pressing the “x” key on your keyboard when you are in the lecture hall. You will be taken to Zoom and return to Gather for the coffee break when the talk is over.  

If you wish to directly access the keynote, use the following link to the Zoom Webinar below. This is also recommended for mobile users because the Zoom integration in Gather is not accessible. However, the three progress reports will be given in Gather only, so better use the Gather link directly, if possible. 

It can be beneficial to get familiar with the Gather platform beforehand for a smooth running of the session and for everyone to fully appreciate the social aspect of the event. As such, we created a small tutorial to help you navigate the options of Gather. You can join the Gather meeting place already now to try things out. On Wednesday, please come early and enjoy discussions with your colleagues.
