Impurity effects on the quasiparticle spectrum of the Fulde-Ferrell-Larkin-Ovchinnikov state of a d-wave superconductor
(American Physical Society, 2006)
In a d-wave superconductor (d-SC), a unitary impurity can induce a near-zero-energy resonant peak in the local tunneling density of states (LTDOS) due to the sign change of the order parameter (OP) on the Fermi surface. ...
Continuum spectroscopy with a (10)C beam: Cluster structure and three-body decay
(American Physical Society, 2009)
Resonance-decay spectroscopy is used to study particle-unbound excited states produced in interactions of E/A=10.7 MeV (10)C on Be and C targets. After inelastic scattering, structures associated with excited states in ...
Measurement of the separation between atoms beyond diffraction limit RID A-5077-2009
(American Physical Society, 2006)
Precision measurement of small separations between two atoms or molecules has been of interest since the early days of science. Here, we discuss a scheme which yields spatial information on a system of two identical atoms ...
Atom localization and center-of-mass wave-function determination via multiple simultaneous quadrature measurements RID A-5077-2009
(American Physical Society, 2007)
We discuss localization and center-of-mass wave-function measurement of a quantum particle using multiple simultaneous dispersive interactions of the particle with different standing-wave fields. In particular, we consider ...
Branching ratios for the beta decay of Na-21
(American Physical Society, 2006)
We have measured the beta-decay branching ratio for the transition from Na-21 to the first excited state of Ne-21. A recently published test of the standard model, which was based on a measurement of the beta-nu correlation ...
Hadron production from quark coalescence and jet fragmentation
(American Physical Society, 2005)
Transverse momentum spectra of pions, protons, and antiprotons in Au+Au collisions at intermediate RHIC energy root s(NN)=62 GeV are studied in a model that includes both quark coalescence from the dense partonic matter ...
New analysis of O-14 beta decay: Branching ratios and conserved vector current consistency
(American Physical Society, 2005)
The ground-state Gamow-Teller transition in the decay of O-14 is strongly hindered and the electron spectrum shape deviates markedly from the allowed shape. A reanalysis of the only available data on this spectrum changes ...
Isoscalar E0, E1, and E2 strength in Ca-40
(American Physical Society, 2001)
The giant resonance region from 10 particles at small angles including 0 degrees. Strength corresponding to 97 +/- 11%, 108 +/- 12%, and 62 + 10-20 % of the isoscalar E0, E2, and E1 sum rules, respectively, was identified ...
Teleportation of an atomic momentum state
(American Physical Society, 2003)
In this paper, we propose a scheme for teleportating a superposition of atomic center-of-mass momentum states to a superposition of the cavity field using quantum controlled-NOT gate via atomic scattering in the Bragg ...
