We propose and demonstrate a novel approach for controlling the temporal position of the biphoton correlation function using pump frequency tuning and dispersion cancellation; precise waveguide engineering enables biphoton generation at different pump frequencies while the idea of nonlocal dispersion cancellation is used to create the relative signal-idler delay and simultaneously prevents broa...

Fig.2. STEAM spectra (around 2.54 ppm) of GSH from phantom (black) and simulation (red) at the optimized (TE, TM) = (72 ms,73 ms). The spectrum from phantom was smoothed with a 5-Hz line broadening and the simulated spectrum was also smoothed to match the line width of the phantom spectrum. Measurement of Glutathione (GSH) Using A Standard STEAM Sequence with Optimized (TE, TM) Parameters: Spec...

A novel transient scattering technique is proposed for femtosecond dephasing time measurements. This technique provides several advantages compared with existing techniques for time-domain dephasing measurements, including resolution below the pulse width, insensitivity to rapid energy relaxation, and clear demarcation between homogeneous and inhomogeneous broadening. We report experimental res...

Shift and broadening of isolated neutral helium lines 7281 angstroms (2(1)P-3(1)S), 7065 angstroms (2(3)P-3(3)S), 6678 angstroms (2(1)P-3(1)D), 5048 angstroms (2(1)P-4(1)S), 4922 angstroms (2(1)P-4(1)D), and 4713 angstroms (2(3)P-4(3)S) in a dense plasma are investigated. Based on a quantum statistical theory, the electronic contributions to the shift and width are considered, using the method ...

The classical four-pulse experiment as invented by W A U G H , H U B E R , and H Ä B E R L E N 2 has been proven to be very effective in reducing the dipolar broadening in the nmr spectra of solids and unravelling weaker interactions such as magnetic shielding anisotropics, /-coupling etc. 3. There is a considerable amount of other types of line narrowing experiments which are capable of reduci...

The shape and shift of the 535.0 nm thallium line resulting from the photodissociation of thallium iodide perturbed by krypton and xenon were investigated at low densities. The Doppler and collision broadening components of the line shape have been determined. The linear dependence of both the Lorentzian half-width and the shift on the perturbing gas density was found and interpreted in terms o...

We report first-principles studies of electronic transport and rectification in molecular wires attached to gold electrodes. Our ab initio calculation gives an accurate description of the voltage drop as well as the broadening and alignment of the molecular levels in the metal-molecule-metal complex. We find that the operation range and rectification in such strongly chemisorbed molecules is li...

A recent two-dimensional prototype model for the initiation of kink banding in compressed layered structures is extended to embrace the two propagation mechanisms of band broadening and band progression. As well as interlayer friction, overburden pressure and layer bending energy, the characteristics of transverse layer compressibility and foundation stiffness are now included. Experiments on c...

The action density distribution associated with confining flux tube is investigated in SU(2) lattice gauge theory at widely varied lattice spacing. It is argued that the gluon condensate vanishes on the string symmetry axis. We qualitatively confirm the widening of the string with increase of sources separation, however, the broadening seems to be a subleading effect. Instead, it is argued that...

Simultaneous two-wavelength polarization and radiance distributions have been obtained for 22 degrees parhelia in four Antarctic ice-crystal swarms that extended to ground level. Samples of crystals that produced these parhelia were collected and replicated. The wavelength dependence of the width of the halo polarization peak agrees with Fraunhofer diffraction theory, indicating that the broade...
