Theory Team
The research activities of THEORIE are devoted to the theoretical study of strongly correlated quantum materials, equilibrium and non-equilibrium many-body physics, critical phenomena, quantum optics, transport and quantum information. State-of-the-art theoretical techniques are developed and applied in order to explore fundamental physics and also to investigate quantum device functionalities.

Exact low-energy duality in superconducting quantum circuits
The THEORIE team, in collaboration with Michel H. Devoret, has published a theoretical study in Physical Review Letters demonstrating an exact low-energy duality in circuits where a Josephson junction is coupled to a multi-mode environment. These systems exhibit a...
Emergent Equilibrium in All-Optical Single Quantum-Trajectory Ising Machines
A collaboration between the Theory group at MPQ, CREF Rome, and Sapienza University of Rome has shown that multimode all-optical systems driven by two-photon processes can reach thermal equilibrium at the level of single quantum trajectories. The study is published in...
Cavity-enhanced fractional quantum Hall phases and cavity-modified spin splittings
A collaboration between the Equipe Théorie at MPQ and scientists from ETH Zurich and the Flatiron Institute has demonstrated, both theoretically and experimentally, that giant vacuum fields confined in a split-ring resonator cavity can profoundly alter...
Emergent quantum phase transition in superconducting circuits
The THEORIE team has recently published a significant theoretical study in Nature Communications on the topic of quantum critical phenomena. This research addresses a current debate that questions the traditional understanding of dissipative quantum phase transitions...
