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.

Quantum limited heat flow and heat Coulomb blockade in a ballistic quantum channel.
(CNRS / Paris Sud University)
Quantum physics predicts that there is a fundamental maximum heat conductance across a single transport channel, and that this thermal conductance quantum GQ is universal, independent of the type of particles carrying the heat. However, the behaviour of electrons in small electronic circuits is dictated by both Coulomb interactions and quantum mechanics. Using sensitive noise thermometry at very low temperatures, we are able to measure the thermal conductance quantum in a ballistic electron channel. At the lowest temperatures we also observe that, when a small metallic circuit node is connected to several channels, inter-channel correlations suppresses exactly one thermal conductance quantum, whereas the electrical conductance is unchanged, demonstrating a large departure from the Wiedemann-Franz law paradigm. This finding establishes the different nature of the quantum laws for thermal transport in nanocircuits.
