Multiple scales and exotic criticality near quantum phase transitions

Subject Area Theoretical Condensed Matter Physics
Term from 2007 to 2017
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 48554140
 
The theory of quantum phase transitions is mainly based on the concept of scaling anduniversality, i.e. on the concept that a single length and time scale diverges at the criticalpoint. However, in many experimentally relevant cases, multiple diverging time scales governthe physics. In this project we study theoretically quantum criticality with multiple scales ingeneral using the physics of phonons and structural phase transitions driven by criticalfluctuations as one example.
