(American Physical Society, 2003)The N-14(p,gamma)O-15 reaction, which controls energy production in the CNO cycle, has contributions from both resonance and direct captures to the ground and excited states. The overall normalization of the direct captures ...
-
(American Physical Society, 2010)We set up a framework in which in-medium charmonium properties are constrained by thermal lattice quantum chromodynamics and subsequently implemented into a thermal rate equation enabling the comparison with experimental ...
-
(American Physical Society, 2007)We report the observation of a coherent multimode instability in quantum cascade lasers (QCLs), which is driven by the same fundamental mechanism of Rabi oscillations as the elusive Risken-Nummedal-Graham-Haken (RNGH) ...
-
(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 ...
-
(American Physical Society, 2007)We present a largely analytical theory for two-photon correlations G((2)) between Stokes (s) and anti-Stokes (a) photon pairs from an extended medium (amplifier) composed of double-Lambda atoms in counterpropagating geometry. ...
-
(American Physical Society, 2007)We investigate the time evolution of entanglement of various entangled states of a two-qubit system exposed to either thermal or squeezed reservoirs. We show that, except for the vacuum reservoir, the sudden-death of ...

-
(American Physical Society, 2009)We propose a scheme for the entanglement generation of two cavity modes using a four-level Raman-driven quantum-beat laser (QBL). The atomic coherence is generated by a Raman-type two-photon process. Two different sufficient ...
-
(American Physical Society, 2009)We demonstrate how to efficiently derive a broad class of inequalities for entanglement detection in multimode continuous variable systems. The separability conditions are established from partial transposition (PT) in ...
-
(American Physical Society, 2007)In this paper, we study the effect of phase fluctuations of the pump field upon the entanglement generation in a two-photon correlated emission laser (CEL). We consider initial vacuum and coherent state for the two-cavity ...
-
(American Physical Society, 2001)Strength functions for isoscalar dipole excitations in Zr-90, Sn-116, and Pb-208 have been measured with inelastic scattering of 240 MeV alpha particles at small angles. The isoscalar E1 strength distribution in each nucleus ...
-
(American Physical Society, 2011)The giant resonance region from 9.5 MeV < E(x) < 40 MeV in (48)Ca has been studied with inelastic scattering of 240-MeV alpha particles at small angles, including 0 degrees. 95(-15)(+11)% of E0 energy-weighted sum rule ...
-
(American Physical Society, 2007)A remarkable progress towards functional ferromagnetic semiconductor materials for spintronics has been achieved in p-type (Ga,Mn)As. Robust hole-mediated ferromagnetism has, however, been observed also in other III-V hosts ...
-
(American Physical Society, 2008)The (15)N(p,gamma)(16)O reaction provides a path from the CN cycle to the CNO bi-cycle and CNO tri-cycle. The measured astrophysical factor for this reaction is dominated by resonant capture through two strong J(pi) = 1(-) ...
-
(American Physical Society, 2008)We study a four-level double-Lambda atomic configuration working as a two photon linear amplifier where two atomic transitions independently interact with cavity mode, while the other transitions are driven by a strong ...
-
(American Physical Society, 1998)The midgap surface states predicted previously to exist on non-{n0m} surfaces of d(xa2-xb2-) superconductors (SC's) can be extended to midgap interface states (MIS's), which exist at almost all interface between grains of ...
-
(American Physical Society, 2004)The cross section for theta(+) production from the reaction gammap-->pi(+)K(-)theta(+), which was observed in the CLAS experiment at the Jefferson National Laboratory, is evaluated in a hadronic model that includes couplings ...
-
(American Physical Society, 2004)The cross sections for production of the pentaquark baryon Xi(5)(+) from the reaction gammap-->K(0)K(0)Xi(5)(+) and of Xi(5)(--) from the reaction gamman-->K(+)K(+)Xi(5)(--) are evaluated in a hadronic model that includes ...

(American Physical Society, 2010)We consider the effect of nonmagnetic impurities on the onset temperature T* for the d-wave pairing in spin-fluctuation scenario for the cuprates. We analyze intermediate coupling regime when the magnetic correlation length ...
