We analyze a lifetime-broadened four-state four-wave-mixing (FWM) scheme in the ultraslow propagation regime and show that the generated FWM field can acquire the same group velocity and pulse shape as those of an ultraslow pump field. We show that a new

A combination of one- and two-photon photoelectron spectroscopies are used to determine the electronic structure around the Fermi level for self-assembled monolayers of a prototypical molecular wire , 4,4 -(ethynylphenyl)-1-benzenethiol (C6H5-C≡C-C6H4-C≡C-
Vibrationally resonant sum frequency generation (VR-SFG) is used to determine the structure of the phenyl side groups of deuterated polystyrene at the liquid/solid interface for the nonsolvent liquids: hexane, methanol, ethanol, glycerol, and water. The
We consider a multi-level medium initially prepared with a coherent superposition of two initial levels that are not directly dipole-coupled. We study the production of multi-wave mixing in the coherent medium, where the process begins on one and
We show the formation of ultraslow bright and dark optical solitons in a lifetime-broadened three-state atomic system under Raman excitation. We also discuss why such ultraslow optical solitons may not exist under the conditions of the usual

Drug testing is widely used throughout the criminal justice system. Currently, most drug testing is based on urine analysis. Although recent alternative drug testing techniques such as hair analysis and on-site kits have become available, laboratory-based
