Title: Ghost orbit spectroscopy

Abstract

Direct periodic-orbit expansions of individual spectral eigenvalues is a new direction in quantum mechanics. Using a unitary S-matrix theory, we present exact, convergent, integral-free ghost orbit expansions of spectral eigenvalues for a step potential in the tunneling regime. We suggest an experiment to extract ghost orbit information from measured spectra in the tunneling regime (ghost orbit spectroscopy). We contrast our unitary, convergent theory with a recently published nonunitary, divergent theory [Yu. Dabaghian and R. Jensen, Eur. J. Phys. 26, 423 (2005)].

  • It is well known that, in Landau gauge, the renormalization function of the ghost-ghost-gluon vertex Z-tilde1 (p2) is finite and constant, at least to all orders of perturbation theory. On the other hand, a direct non-perturbative verification of this result using numerical simulations of lattice QCD is still missing. Here we present a preliminary numerical study of the ghost-ghost-gluon vertex and of its corresponding renormalization function using Monte Carlo simulations in SU(2) lattice Landau gauge. Data were obtained in 4 dimensions for lattice couplings {beta} = 2.2, 2.3, 2.4 and lattice sides N = 4, 8, 16.
  • Fluorescence and excitation spectra arising from transitions between excited states of the HgCd excimer molecule were produced in a mixture of Hg and Cd vapors following pump and probe laser excitation. The vapor mixture contained in a sealed quartz cell was irradiated by pulsed pump (326.1 nm) and probe (430-475 nm) laser beams, delayed by 450 ns relative to one another. The fluorescence bands were recorded with a high-resolution monochromator, an RCA 31034A photomultiplier, and a Hewlett-Packard 54111D digitizing oscilloscope controlled by a microcomputer. In addition to the previously reported and analyzed {open_quotes}blue-band{close_quotes} fluorescence that can be excited with amore » single laser, we observed short-lived and structured fluorescent bands as well as the corresponding excitation bands in the blue spectral region, which we assigned to transitions between specific states of HgCd. An analysis of the bands yielded the vibrational constants for some of the states, as well as their relative internuclear equilibrium separations. These results provide an initial basis for the production of a partial PE diagram consisting of spin-orbit states correlated to the 5{sup 3}P manifold in Cd.« less
  • We examine the degree of 5f electron localization in URu{sub 2}Si{sub 2} using spin-orbit sum rule analysis of the U N{sub 4,5} (4d {yields} 5f) edge. When compared to {alpha}-U metal, US, USe, and UTe, which have increasing localization of the 5f states, we find that the 5f states of URu{sub 2}Si{sub 2} are more localized, although not entirely. Spin-orbit analysis shows that intermediate coupling is the correct angular momentum coupling mechanism for URu{sub 2}Si{sub 2} when the 5f electron count is between 2.6 and 2.8. These results have direct ramifications for theoretical assessment of the hidden order state ofmore » URu{sub 2}Si{sub 2}, where the degree of localization of the 5f electrons and their contribution to the Fermi surface are critical.« less
  • The technique of velocity-aligned Doppler spectroscopy (VADS) is used to investigate the photodissociation of HBr (193 nm) and HI (193 and 248 nm). Doppler profiles at Lyman-..cap alpha.. for the H-atom photofragment are reported, and the corresponding populations of the halogen atom /sup 2/P/sub 3/2/ and /sup 2/P/sub 1/2/ spin-orbit states are determined. The VADS technique facilitates measurement of spatial anisotropy (..beta..'s) for each spin-orbit state. For HI photolyzed at 248 nm, I(/sup 2/P/sub 3/2/) and I(/sup 2/P/sub 1/2/) are produced with relative populations 0.54 /plus minus/ 0.05 (..beta.. = -1.0 /plus minus/ 0.2) and 0.46 /plus minus/ 0.05 (..beta..more » = 1.7 /plus minus/ 0.2), respectively, while 193-nm HI photodissociation yields an I(/sup 2/P/sub 3/2/) population of greater than or equal to 0.9 (..beta.. approx. /minus/1.0). For 193-nm HBr photodissociation, the Br(/sup 2/P/sub 3/2/) and Br(/sup 2/P/sub 1/2/) populations are 0.86 and 0.14, respectively. Surprisingly, both channels appear to originate primarily from a perpendicular transition, since ..beta.. is /approximately/ /minus/1.0 for each state. This is in contrast to the case of HI, and plausible excitation and dissociation mechanisms are discussed in terms of possible coupling schemes.« less
  • We report extensive measurements of rovibronic levels in the 020/100 and 040/120/200 Fermi-resonant polyads of NCO. The levels were accessed by the technique of stimulated emission pumping spectroscopy in a supersonic free jet expansion following excitation of bands in the {ital {tilde A}} {sup 2}{Sigma}{sup +}{minus}{ital {tilde X}} {sup 2}{Pi} spectrum of the radical. The data were analyzed in terms of an effective Hamiltonian which explicitly included reference to all the possible vibronic levels of {sup 2}{Pi} symmetry in the polyad under consideration. The effects of levels outside these were treated by perturbation theory. The model was successful in fittingmore » the data close to the experimental measurement precision and the resulting parameters were interpreted in terms of the harmonic and anharmonic vibrational terms. The effective Renner--Teller coupling parameter in NCO varied with vibrational level; however, parameters describing the Fermi-resonance interaction were found to be constant for all the levels investigated.« less
