Feedback control of coherent and collective quantum processes (A07)

• Subject Area: Theoretical Condensed Matter Physics
• Term: from 2011 to 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 163436311

We will develop a theoretical description of delayed feedback control for quantum transport processes, implement a microscopic analogon of coherent feedback control, and provide a thorough thermodynamic interpretation of feedback in presence of quantum coherence. We will furthermore introduce delayed feedback control for dissipative quantum phase transitions and study the phase diagram and the appearance of quantum chaos in Dicke-Hepp-Lieb superradiance and other models.
