HIGHLIGHTS
- who: Zu-Jian Ying and collaborators from the Institute for Complex Systems, National Research Council (ISC-CNR), Rome, Italy EP VI and Center for Electronic Correlations and Magnetism, University of Augsburg have published the Article: Critical Quantum Metrology in the Non-Linear Quantum Rabi Model, in the Journal: Entropy 2022, 24, 1015. of /2022/
- what: The authors show that the QRM including a nonlinear coupling term exhibits much higher measurement precisions due to its first-order-like phase transition at finite frequency avoiding the detrimental slowing-down effect close to the point of the linear . . .
