Beyond-Third-Order Quantum Coherence in Two-Dimensional Spectroscopy via Order-Selective Isolation
Xue Zhang, De-Ran Zhang, Hui Dong
A central challenge in nonlinear spectroscopy is the order-selective readout of weak higher-order responses that spectrally overlap with dominant lower-order signals. This bottlene…

Note on the noise reduction in spectroscopic detection with compressed sensing
Junyan Sun, Deran Zhang, Ziqian Cheng +2
Spectroscopy sampling along delay time is typically performed with uniform delay spacing, which has to be low enough to satisfy the Nyquist-Shannon sampling theorem. The sampling t…
