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 with interactions that decay weakly with distance
248 (Building C, First Floor)
Building C, First Floor
Systems with long-range interactions, like gravitational, charged and
dipolar systems, can be made extensive, but are intrinsically non additive.
The violation of this basic property of thermodynamics is the origin of
ensemble inequivalence, which in turn implies that specific heat can be
negative in the microcanonical ensemble, temperature jumps may appear at
microcanonical first order phase transitions, ergodicity is tipically
broken. From the dynamical point of view, these systems can be trapped in long-lived
quasi-stationary states whose lifetime diverges with system size.
Realizing that such features are present for a wide class
of models has renewed the interest in long-range interactions.
