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.

Dark Energy vs. Dark Matter: Towards a unifying scalar field?
The Dark Matter and Dark Energy problems are presently two of the most
important questions in cosmology. Many theoretical models try to
determine the nature of these two components, however none of them has
until now given a fully satisfying answer. In this seminar, I will
present first the cosmological context of these questions. Then, I will
describe a scalar field model able to explain at the same time indirect
observations of dark matter and of dark energy, therefore enabling to
unify both components into a unique dark fluid.
Finally, I will consider quantum field theory to build an adequate
potential for this scalar field.
