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.

There are strong indications that Einstein gravity can be derived from a microscopic description of emergent spacetime in terms of entangled quantum information. An essential ingredient in the derivation of the Einstein equations is that the entanglement entropy of the vacuum obeys an area law. In Anti-de-Sitter space this condition is known to hold due to the work of Ryu and Takayanagi. We will argue that in de Sitter space due to the positive dark energy, that the microscopic entanglement entropy also contains also a volume law contribution in addition to the area law. This volume law contribution is related to the thermal properties of de SItter space and leads to a total entropy inside the static patch that precisely matches the Bekenstein-Hawking formula for the cosmological horizon. We study the effect of this extra
contribution in the derivation of the emergent laws of gravity, and argue that it leads to a modification compared to Einstein gravity. We provide evidence for the fact this modification explains the observed
phenomena in galaxies and clusters currently attributed to dark matter.
