Controlling Collective Phenomena Via the Quantum State of Interaction-Mediators: Changing the Criticality of Photon-Mediated Superconductivity Via Fock States of Light
Ahana Chakraborty, Michele Pini, Martina S. Zündel +1
How are two-body scattering and the resulting collective phenomena affected by preparing the mediator of interactions in different quantum states? This question has recently become…

Charge and Entanglement Criticality in a U(1)-Symmetric Hybrid Circuit of Qubits
Ahana Chakraborty, Kun Chen, Aidan Zabalo +2
We study critical properties of the entanglement and charge-sharpening measurement-induced phase transitions in a non-unitary quantum circuit evolving with a U(1) conserved charge.…
