Geza Giedke will visit us

Prof. Geza Giedke (Max-Planck-Institut für Quantenoptik and TU München, Garching, Germany) will be visiting us on June 14th and 15th and will give a talk on Friday 15th at 10 am, on "Spin Physics in Open and Driven Quantum Dots".

Abstract: The electron spin in a quantum dot interacts with a large number of nuclear spins, realizing a central spin system. The fast control of the central electronic spin and the long nuclear spin lifetimes suggests the use as a versatile quantum register and enables the study of many-body quantum effects. We discuss some QIP applications such as dissipative state preparation, but focus on the steady state properties of the driven central spin system. We show that it features first and second order dissipative phase transitions and present methods to analyze them.
