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.

A variety of systems displays critical phenomena, from boiling water, through ferromagnets and superconductors. Remarkably, many distinct systems can behave in the same way at their critical point. In this talk I will review how we can understand this through the renormalization group, and how criticality is governed by so-called conformal field theories (CFTs). I will show how in recent years our understanding of CFTs has improved dramatically, and how this has helped understand systems ranging from boiling water to quantum gravity.
