In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Models of light pseudoscalar fields coupled to electromagnetism are quite common in theoretical physics. They predict "optical-activity-type" phenomena, if polarized SM particles propagate over region with non-vanishing gradients of such fields. Recent observation of the curl-type patterns in the CMB polarization require a second look at these models, as possible alternatives to the tensor mode origin of B-modes. I will show how massless pseudoscalar field fluctuations generated by inflation lead to a very specific pattern of the BB correlation, which can be compared with recent observations. I will also argue that massive pseudoscalar fields can also lead to a similar mechanism, if there exist stable remnants in the form of the domain walls of axion-like fields. Recent experimental activity to initiate the search for such domain walls will be described.
