Weak-measurement-induced asymmetric dephasing: Manifestation of intrinsic measurement chirality
Geometrical dephasing is distinct from dynamical dephasing in that it depends on the
trajectory traversed, hence it reverses its sign upon flipping the direction in which the path is …

Geometric phase and non-adiabatic resonance of the Rabi model
S Liu, Z Lü, H Zheng - Journal of Physics A: Mathematical and …, 2021 - iopscience.iop.org
We investigate the effects of counterrotating terms on geometric phase and its relation to the
resonance of the Rabi model. We apply the unitary transformation with a single parameter to …
