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…

Measurement Uncertainty in Infrared Spectroscopy with Entangled Photon Pairs

Xue Zhang, Zhucheng Zhang, Hui Dong

Spectroscopy with entanglement has shown great potential to break limitations of traditional spectroscopic measurements, yet the role of entanglement in spectroscopic multi-paramet…

Temperature shift of magnetic-field-dependent photoluminescence features of nitrogen-vacancy ensembles in diamond

Irena Rodzoń, Xue Zhang, Viktor Ivády +3

Recently significant attention has been paid to magnetic-field-dependent photoluminescence (PL) features of the negatively charged nitrogen-vacancy (NV) centers in diamond. These f…

Quantum-enhanced weak absorption estimation with correlated photons

Zhucheng Zhang, Xue Zhang, Jing Liu +1

Conventional absorption spectroscopy relies on coherent laser sources, and in turn suffers from the inherent limitation of shot noise, especially in estimating weak absorption. Her…

Coherent amplitude modulation of continuous-wave light in cesium vapor

X. Zhang, J. B. Kim, D. Antypas

We report on observations of coherent, sustained oscillations in the absorption of continuous-wave light at 388 nm that excites the transition in ces…

Extracting double-quantum coherence in two-dimensional electronic spectroscopy under pump-probe geometry

Mao-Rui Cai, Xue Zhang, Zi-Qian Cheng +2

Two-dimensional electronic spectroscopy (2DES) can be implemented with different geometries, e.g., BOXCARS, collinear and pump-probe geometries. The pump-probe geometry has its adv…

Isomeric excitation of ^{229}\mathrm{Th} via scanning tunneling microscope

Xue Zhang, Tao Li, Xu Wang +1

The low energy of the isomeric state of the radionuclide thorium-229 (229Th) makes it highly promising for applications in fundamental physics, precision metrology, and quantum tec…
