Transformations between perfect and imperfect quantum reference frames
Sébastien Garmier – PhD student in QIT group (Prof. Renato Renner) at ETH Abstract Any observer performing a measurement does so relative to a physical system serving as a reference frame, which, when treated quantum-mechanically, leads to the notion of quantum reference frames. Starting with the points of view of such observers and using an…

The road to the Ultraviolet: Effective Field Theories in Particle Physics
Dr. Achilleas Lazopoulos – Senior Scientist at the Particle Physics group of ITP, ETHZ Abstract Our quest for an ultimate theory of elementary particles is taking a new turn as the Large Hadron Collider goes on inspecting the structure of the microscopic world at the energy range of the TeV without discovering new particles. How…

Testing Quantum Theory With Thought Experiments
Prof. Dr. Renato Renner – Professor at the ETH Institute for Theoretical Physics Abstract According to quantum theory, objects can be in states without classical analogues. For example, in the famous double-slit experiment, a particle may be in a superposition of passing through two different slits at the same time. Such superposition states are well…
