Lee-Yang theory of phase transitions in interacting quantum many-body systems

Project description

Lee-Yang theorem extends to the quantum realm to describe quantum many-body systems

Lee-Yang theory provides a description of phase transitions and analytic properties of thermodynamic functions based on the distribution of partition function zeros. Lee-Yang zeros are no longer just a theoretical concept; they have recently been determined from measurements of fluctuating observables, offering a completely new perspective on phase transitions in interacting many-body systems. The EU-funded QuLeeYang project will expand the Lee-Yang theory beyond classical equilibrium systems. It will formulate a unifying theory of phase transitions in interacting quantum many-body systems from the perspective of Lee-Yang zeros and will make use of engineered quantum devices to test the predictions about phase transitions. The project's results will have important implications for quantum information processing and quantum thermodynamics.
